Molecular phylogeny of plant pathogenic fungi based on start codon targeted (SCoT) polymorphism
(Springer, 2023) Palacıoğlu, Gülsüm; Alkan, Mehtap; Derviş, Sibel; Bayraktar, Harun; Özer, Göksel
Background: A number of molecular marker systems have been developed to assess genetic diversity, carry out phylogenetic analysis, and diagnose and discriminate plant pathogenic fungi. The start codon targeted (SCoT) markers system is a novel approach used here to investigate intra and interspecific polymorphisms of phytopathogenic fungi. Materials and methods: This study assessed genetic variability between and within 96 isolates of ten fungal species associated with a variety of plant species using 36 SCoT primers. Results: The six primers generated 331 distinct and reproducible banding patterns, of which 322 were polymorphic (97.28%), resulting in 53.67 polymorphic bands per primer. All primers produced informative amplification profiles that distinguished all fungal species. With a resolving power of 10.65, SCoT primer 12 showed the highest polymorphism among species, followed by primer 33 and primer 29. Polymorphic loci (PPL), Nei's diversity index (h), and Shannon index (I) percentages were 6.25, 0.018, and 0.028, respectively. UPGMA analysis separated all isolates based on morphological classification and revealed significant genetic variation among fungal isolates at the intraspecific level. PCoA analysis strongly supported fungal species discrimination and genetic variation. The other parameters of evaluation proved that SCoT markers are at least as effective as other DNA markers. Conclusions: SCoT markers were effective in identifying plant pathogenic fungi and were a powerful tool for estimating genetic variation and population structure of different fungi species.
Assessment of Parametric and Non-parametric Methods for Selecting Stable and Adapted Durum Wheat Genotypes in Multi-Environments
(Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2010) Kılıç, Hasan; Akçura, Mevlüt; Aktaş , Hüsnü
Seventeen parametric and non-parametric methods for grain yield of 5 cultivars and 20 advanced durum wheat genotypes evaluated across 10 environments during the 2004-2007 growing seasons were used to assess performance stability and adaptability of the genotypes as well as to study interrelationship among these methods. Biplot analysis based on the rank correlation matrix indicated that most non-parametric methods were significantly inter-correlated with parametric methods. The results also showed that stability methods could be classified into four groups based on biplot analyses. The group related to the dynamic stability concept and strongly correlated with mean grain yield included the parameters of regression coefficient (bi), alpha (αi), TOP (proportion of environments in which a genotype ranked in the top third), environmental variance (Si2), coefficient of variation (CVi), Di2, Si(3) and Si(6). The second group included Wricke’s ecovalence (Wi2), the Huehn’s parameters [Si(1) Si(2)], Shukla’s stability variance (σ2i), Plaisted and Peterson’s parameter (P59) and Tai’s model (λi) which were influenced by both yield and stability simultaneously. The third group included Kang’s parameter (RS) and superiority index (Pi), which only measures stability. Genotypes 18, 16 and 2 were most stables based on parametric and non-parametric stability methods used.
EFFECT OF HUMIC ACID AND PHOSPHORUS APPLICATIONS ON THE YIELD AND YIELD COMPONENTS IN LENTIL (LENS CULINARIS MEDIC.)
(Legume Res., 2014)
Lentil is commonly grown as a rotation crop in east and southeast of Turkey. It is an important crop because of its high protein content of seed and straw for human and animal nutrition. Phosphorus in the soil has developmental activity in the plant’s root growth. The effects of humic substances on plant growth, under conditions of adequate mineral nutrition, consistently show positive effects on plant biomass. An experiment was conducted to study the effect of different levels of humic acid and phosphorous on yield and yield attributes of lentil during 2008-09 and 2009-10 in Agricultural Faculty experiment field of Yuzuncu Yil University. The results of the study indicated that humic acid and phosphorus applications increased significantly the seed yield and yield components. Whereas the highest seed yield were obtained from 80 kg phosphorus ha-1 with 1135 kg ha-1 and 600 kg humic acid ha-1 application with 1097 kg ha-1 in the first year, the values were 80 kg phosphorus ha-1 with 1756 kg ha-1 and 600 kg humic acid ha ha-1 application with 1625 kg ha-1 in the second year

MATURE EMBRYO CULTURE IN BARLEY (Hordeum vulgare L.) UNDER DIFFERENT CONCENT TIONS OF SODIUM AZIDE
(FRESENIUS ENVIRONMENTAL BULLETIN, 2021) Alsoudan, Ismaeil; Haliloglu, Kamil; Kosunkartay, Hasan; Kızılgeçi, Ferhat; Kutlu, Meral
The present study was performed to determine the effects of different genotypes and concentrations of sodium azide on callus formation and plant regeneration from endosperm supported mature embryo derived calli of barley. Callus formation of endosperm supported mature embryos of two barley genotype were cultured in MS medium with five different concentrations of sodium azide (NaN3) (0, 10(-4), 10(-3), 10(-2), and 10(-1) mM). Results revealed that the main effects of both genotypes, sodium azide concentrations and their interactions on callus and embriogenic callus development and regeneration were significant or highly significant, suggesting that genotypes responded differently to the different sodium azide concentrations. The application of sodium azide application decreased the callus induction rate, embryogenic callus rate, responded embryogenic callus rate and regeneration efficiency. When evaluating the concentrations based on the averages, the highest regeneration efficiency and responded embryogenic callus rate were obtained at 10(-1) mM and 10(-4) mM concentrations, respectively, compared with the control. The highest callus induction rate (81.12%) in Alcar genotype and the highest regeneration efficiency (1.99 plants) were observed in OI-gun genotype.

PROFICIENCY OF BIPLOT METHODS (AMMI AND GGE) IN THE APPRAISAL OF TRITICALE GENOTYPES IN MULTIPLE ENVIRONMENTS
(CORVINUS UNIV BUDAPEST, 2019) Kendal, Enver; Tekdal, Sertaç; Karaman, Mehmet
The AMMI (additive main effect and multiplicative interaction) and GGE (genotype, genotype x environment) biplot analyses were used to evaluate and identify stability and yield of Triticale genotypes at three different locations throughout two years (2014-15-2015-16). The AMMI analysis of variance showed significant genotype, environment and GE interaction and indicated 1.31, 98.40 and 0.28% of total variation, respectively. The GGE bi-plot analysis indicated 78.19% of the total variation (PC1 (priciple component) 50.01%, and PC2 26.08%). This study has been useful to discriminate genotypes with superior and stable yield evaluated by the AMMI analysis and yield stability index incorporating the AMMI stability value and yield capacity in a single non-parametric index. The AMMI analysis indicated that G4, G8 (candidate) and G6 were found to be quite promising genotypes. In the GGE biplot analysis genotypes were investigated in two mega-environments, and the first mega-environment covered E3, E5 and E6, and the second mega-environment covered E1, E2 and E4. The genotypes G6, G8, G9 and Gll were the wining genotypes in ME (mega-environment) I, G3, G4 and G12 and in ME II. The GGE and AMMI biplot approaches let us to describe the best genotypes, and G8 to be stable and high yielding for both ME, G6 only for ME I, G4 only for ME II and can be recommended to release as a cultivar.

(Kahramanmaraş Sütçü İmam Üniversitesi Tarım ve Doğa Dergisi, 2022) Derviş, Sibel; Türkölmez, Şahimerdan; Eren, Abdullah; Özer, Göksel
In this study, a total of 78 Talaromyces isolates were isolated from the pistachio (Pistacia vera L.) rhizosphere heavily infested with Neoscytalidium spp. The identification studies of the four representative isolates based on morphological and molecular methods showed that all isolates were T. funiculosus. The 575 bp long sequence of the internal transcribed spacer region of T. funiculosus isolate ST976, selected as a representative of the isolates, was deposited in GenBank under accession no. MW130842. The Maximum Likelihood tree clustered the ST976 isolate with reference T. funiculosus isolates derived from the GenBank nucleotide database. The phosphorus dissolution ability of ST976 isolate was determined by an experiment using six soil samples collected from agricultural lands in various locations of Şanlıurfa province. The pH of the soil samples taken varied between 7.21 and 7.88. As a result of the analysis performed with the addition of the isolate ST976 applied to soil samples with different soil structures (Clay and Clay-Loam), it was determined that the isolate ST976 dissolved 109–311% more phosphorus than the control sample. The study is one of the first studies proving the ability of T. funiculosus isolate ST976 to dissolve phosphorus without any additives to soil solution was determined.

Effects of chemical, organic and microbial fertilization on agronomical growth parameters, seed yield and chemical composition of chickpea
(POLISH SOCIETY MAGNESIUM RESEARCH, 2023) Doğan, Serap; Çığ, Fatih
Because of its valuable nutritional content, chickpea is expected to become the most important crop for the increasingly larger global population. Therefore, this research was carried out in 2018 and 2019 to investigate the effects of microbial (Bacillus-GC group, Pseudomonas tetraodonis and Brevibacillus choshinensis), organic (vermicompost and chicken manure) and chemical (DAP/2 ve DAP) fertilizer applications on yield and nutritient content of two different chickpea cultivars (Arda and Azkan). The experiment was laid out according to a randomized complete split-block design with three replications. The results expressed as the average values of two-year experiments projected that the application of chicken manure significantly improved the morphological traits of chickpea plants compared to the other treatments, while the highest phosphorus content was recorded after the application of farm manure. Additionally, the highest grain yield from both cultivars was obtained owing to the application of chicken manure. Apart from this effect, other microbial applications also played a positive role in plant growth and production, but chicken manure excelled in this respect. Thus, it has been concluded that chicken manure could be used as a suitable alternative to chemical fertilizer for chickpea culti vation in order to create a sustainable agricultural system, increase productivity and protect and improve soil properties.

(Necmettin Erbakan Üniversitesi, 2017) İzgi, Mehmet Necat; Telci, İsa
Coriander, Coriandrum sativum L., belonging Apiaceae family is an important spice plant grown in different locations of Turkey. The study was aimed to investigate the composition of fatty acid compositions of 6 coriander cultivars (Gamze, Arslan, Erbaa, Pelmus, Kudret, and Gürb üz) in two different ecologies of Turkey (Tokat and Mardin). The oils obtained with cold extraction were analyzed by Gas Chromatography. In the Results, total 22 fatty acids were identified in the cultivars. Petroelinic acid was the major fatty acid in all varieties, followed by linoleic acid and palmitic acid. The variation of the major fatty acids was limited in the study. The highest amount of petroselinic acid was changed between 80.5-82.6% and the highest value was reached in Arslan variety in Mardin. Palmitic acid, which is saturated fatty acid in all varieties, was found high in Mardin, while unsaturated fatty acid linoleic acid in Tokat. It was concluded that the effect of regions on fatty acids was little in the study.

Objectives: In the present study, the antioxidant potency of ethyl acetate (AcOEt) and methanol (MeOH) extracts from the aerial parts of Seseli L. species was investigated for the first time. Materials and Methods: Seseli species L. such as Seseli andronakii Woronow ex Schischk., S. campestre Besser, S. corymbosum Boiss. & Heldr., S. gummiferum subsp. gummiferum Pall. ex Sm., S. hartvigii Parolly & Nordt, S. libanotis (L.) W.Koch, S. petraeum M.Bieb., S. peucedanoides (M.Bieb.) Koso-Pol., S. resinosum Freyn & Sint., and S. tortuosum L. growing in Turkey were collected and evaluated for their antioxidant capacity by using 1.1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and lipid peroxidation (LPO) inhibition methods. Results: The highest activities as a scavenger of DPPH radicals were found in the AcOEt extracts of S. peucedanoides (M.Bieb.) Koso-Pol (IC50=0.49 mg/mL), and S. libanotis (IC50=0.75 mg/mL); α-tocopherol was used as a positive control. On the other hand, in the LPO assay, the highest activities were determined in AcOEt and MeOH extracts (at 5 mg/mL) of S. tortuosum and S. libanotis (84-94%). Conclusion: This report gives important information about the antioxidant capacity of Seseli L. species. This research on antioxidant capacity proves that the use of some species used in Eastern Anatolia (in salads) is correct. With this screening study performed in Seseli L. species growing in Turkey, in the future, it is planned to isolate antioxidant compounds from the most active strains of Seseli L.

Bu çalışmada, Ayvalık tuzlasında yayılış gösteren Halimione portulacoides (L.) Aellen bitkisi kullanılarak, tuzlanın Pb, Zn ve Cd düzeyleri Perkin Elmer Analyst 700 Model Alevli Atomik Absorbsiyon Spektrofotometresi (FAAS) cihazı kullanılarak belirlenmiştir. Tuzla İzmir-Çanakkale karayolunun bitişiğinde yer aldığından dolayı ayrıca karayoluna olan mesafeye bağlı değişimlerde belirlenmiştir. Bitkinin kök, gövde ve yaprak kısımları ile onun yetişme toprağı çalışmanın materyalini oluşturmuştur. Örneklemeler 2009-2010 yılları arasında, tuzlayı çevreleyen toprak set üzerinde belirlenen yedi istasyonda yapılmıştır. Her istasyondan 12 ay boyunca düzenli olarak numuneler alınmıştır. Yapılan tüm analizler sonucunda bitkide; Pb <0.001-0.977 ppm, Zn 0.099-1.650 ppm, Cd <0.001-0.102 ppm, toprakta ise Pb 0.523- 1.599 ppm, Zn 0.143-1.248 ppm ve Cd 0.006-0.432 ppm arasında olduğu belirlenmiştir. Pb ve Zn birikimi yola olan mesafeye bağlı artmış, Cd birikimi ile yola olan mesafe arasında ise net bir ilişki elde edilememiştir. Analizlerde sonuçların sınır değerlerin altında olmasının en önemli nedeni, hakim rüzgâr yönünün kuzeybatı (tuzladan karayoluna doğru) olması, tuzlanın güneyi boyunca uzanan karayolu üzerinde herhangi bir kavşak ve sinyalizasyonun bulunmaması ve yakınında kirletici özelliği olabilecek endüstri ve sanayi tesislerinin olmamasıdır.

Allelic variations of glutenin subunits and their association with quality traits in bread wheat genotypes
(2017) Aktaş, Hüsnü; Baloch, Faheem Shehzad
The present study was conducted to evaluate the genotype × environment interaction of the yield and quality traits for five bread wheat varieties commonly grown in the Southeastern Anatolia Region of Turkey and 20 advanced lines developed within the framework of the International Winter Wheat Improvement Project. We also determined the allelic pattern of the Glu-1 and Glu-3 loci of these genotypes and examined whether these loci had an effect on the quality traits. There was a significant variation among the genotypes and environments in terms of grain yield, protein content, sedimentation volume (SV), and the extensograph dough energy value (EDEV). The results of the study indicated that genotypic effect was more influential on SV and EDEV than environmental effect; thus, both traits could be used in breeding programs to develop elite cultivars with better quality. Twelve different high-molecularweight (HMW) glutenin alleles were identified at the Glu-A1, Glu-B1, and Glu-D1 loci, resulting in 14 allelic combinations, and 17 different alleles were observed in 19 combinations for low-molecular-weight (LMW) subunits. Furthermore, among all the genotypes, 13 + 16 and 13 + 19 alleles at Glu-B1 and 5 + 12 at Glu-D1 were observed to have the lowest frequency. Our study indicated that the combinations of HMW glutenin alleles with 2* at Glu-A1, 17 + 18 and 13 + 16 at Glu-B1, and 5 + 10 at Glu-D1, as well as the combinations of LMW alleles with subunits c and d at Glu-A3; subunits d, b, c, and g at Glu-B3; and subunits a and b at Glu-D3 had positive effects on the quality traits.
OVERVIEWING SUPERCHARGED FOOD CROPS IN TURKIYE PERSPECTIVES: A WAY FORWARD TO FOOD SECURITY
(2022) Kızılgeçi, Ferhat; Iqbal, Muhammad Aamir
Food and nutritional insecurity, skyrocketing human populace, climate change and stagnate productivity of strategic food crops have emerged as prime challenges of this century. In order to attain UNDP sustainable goal of food security and zero hunger, there is dire need to improve the productivity and nutritional quality of food crops without immense increment in farm input utilization. The supercharged food crops (SFCs) (genetically modified plants entailing potential to grow significantly faster than conventional plants) might contribute produce greater economic yields. Numerous mechanisms such as improvement in photosynthetic efficiency, non-photochemical quenching, imparting C4 life cycle in C3 cereals and enhancing harvest index, are being put into practice for producing SFCs. An amalgamation of genetic engineering and synthetic biology approaches might produce desirable traits. However, future research efforts need to address multiple challenges such as plants traits governed by multiple genes and having little correlation with photosynthesis along with transgenic plants switching back to original physiological pathways.

A Whole Genome DArTseq and SNP Analysis for Genetic Diversity Assessment in Durum Wheat from Central Fertile Crescent
(Public Library Science, 2017) Baloch, Faheem Shehzad; Alsaleh, Ahmad; Shahid, Muhammad Qasim; Ciftci, Vahdettin; de Miera, Luis E. Saenz; Aasim, Muhammad; Hatipoglu, Rustu
Until now, little attention has been paid to the geographic distribution and evaluation of genetic diversity of durum wheat from the Central Fertile Crescent (modern-day Turkey and Syria). Turkey and Syria are considered as primary centers of wheat diversity, and thousands of locally adapted wheat landraces are still present in the farmers' small fields. We planned this study to evaluate the genetic diversity of durum wheat landraces from the Central Fertile Crescent by genotyping based on DArTseq and SNP analysis. A total of 39,568 DArTseq and 20,661 SNP markers were used to characterize the genetic characteristic of 91 durum wheat land races. Clustering based on Neighbor joining analysis, principal coordinate as well as Bayesian model implemented in structure, clearly showed that the grouping pattern is not associated with the geographical distribution of the durum wheat due to the mixing of the Turkish and Syrian landraces. Significant correlation between DArTseq and SNP markers was observed in the Mantel test. However, we detected a non-significant relationship between geographical coordinates and DArTseq (r = -0.085) and SNP (r = -0.039) loci. These results showed that unconscious farmer selection and lack of the commercial varieties might have resulted in the exchange of genetic material and this was apparent in the genetic structure of durum wheat in Turkey and Syria. The genomic characterization presented here is an essential step towards a future exploitation of the available durum wheat genetic resources in genomic and breeding programs. The results of this study have also depicted a clear insight about the genetic diversity of wheat accessions from the Central Fertile Crescent.
The anatomical properties of Salvia section (Lamiaceae) in central district of Mardin (Turkey) and their taxonomic implications
(Journal of advanced research in natural and applied sciences (Online), 2022) Kılıç, Murat; Mungan Kılıç, Fatma
In this study, 4 Salvia species found in the Salvia section distributed in the Artuklu district of Mardin province were analyzed comparatively in terms of anatomy. Plant specimens of Salvia section were collected from 11 localities. Anatomical studies were performed on specimens preserved in 70% alcohol. Transverse sections taken from the roots, stems, leaves, and petioles of the species were examined under a light microscope for anatomical examination. The anatomy of S. bracteata, S. macrochlamys, S. suffruticosa, S. trichoclada species were examined. The S. suffruticosa species was examined in detail for the first time anatomically. The data obtained as a result of the researches were compared with the previous studies on the Salvia section. In anatomical examinations, it was observed that the root, stem, leaf, and petiole structures of the taxa were similar but shapes and measurements in addition to this the number of tissue layers and pith rows are different. Also anatomically analyses, it has been seen that hairiness formed a difference between some species. As a result of all these discussed data, the anatomical characters such as number of ray rows in root, number of collenchyma layers in stem, mesophyll structures in leaves, shape of midrib and number of vascular bundles in petiole, provide important taxonomic information.

Canker and leaf scorch on olive (Olea europaea L.) caused by Neoscytalidium dimidiatum in Turkey
(ScienceDirect, 2022) Güney, İnci Güler; Özer, Göksel; Türkölmez, Şahimerdan; Derviş, Sibel
In a recent survey of olive groves in the Southeast Anatolia Region of Turkey, a new and serious decline of olive trees, beginning with foliar scorching and then dieback of twigs, branches, and even whole trees, was observed for the first time. In more advanced stages of the disease, necrosis and cankers were observed on the bark of the trunk, branches, and twigs. Isolations from symptomatic tissues from multiple cultivars in diverse locations yielded Neoscytalidium dimidiatum, which were identified using ITS, tef1, and tub2 loci of genomic DNA, in combination with morphological data. In vitro studies showed that conidial germination, hyphal growth, and pycnidia formation of the pathogen were positively correlated with elevated temperatures. Wild type olive “Delice”, “Edincik Su”, and “Memecik” seemed like the most resistant cultivars on which disease severity values were the lowest among 14 screened olive cultivars in two experimental orchards under natural conditions. Pathogenicity tests showed that “Gemlik” was the most susceptible cultivar showing the largest cankers and extensive scorch lesions. Isolates caused canker but not leaf scorch on O. europaea cultivars “Arbequina” “Halhalı”, “Manzanilla”, “Nizip Yağlık”, and “Saurani”. Neoscytalidium isolates are likely to have a negative impact on the health of diverse olive groves, which are primarily confined to Mediterranean-type climatic regions. These findings suggest an increased risk of infection in environments with increasing temperatures, as is common in the Southeast Anatolia Region of Turkey. The information gathered in this study will be used to examine the disease's epidemiology and establish disease control initiatives. This is also the first report of N. dimidiatum infecting O. europaea in the world.
