Comparative Adaptation Responses of Melon (Cucumis Melo L.) Genotypes To Salinity Stress
(Tarbiat Modares Univ, 2021) Erdinc, C.; Inal, B.; Erez, E.; Ekincialp, A.; Sensoy, S.
The objective of this work was to understand the mechanisms of physiological, biochemical, and molecular responses to salinity stress of three Turkish melon genotypes (YYU 1, YYU 4 and CU 196) and cv. Ananas. The study used Randomized Complete Block Design (RCBD) and pots were irrigated with Hoagland nutrient solution after two-leaf stage until harvesting by 50 and 75 mM NaCl concentrations. For evaluation of responses, chlorophyll and carotenoid content, total phenolic and flavonoid amount, proline variations, and nutrient elements were determined. Moreover, qRT-PCR analyses were performed to identify the expression level of six TF (Transcription Factors) genes (WRKY24, TCP15, CmHD-Zip, mTERF2, Dof3 and CmADH2). Increase in salt application led to increase in chlorophyll content in the melon genotypes, but decrease (about 55%) in cv. Ananas. Phenolic, flavonoid, and proline contents varied based on the melon genotypes, but generally increased in Ananas. Expression levels of TCP15 and WRKY24 showed more fold change at 75 mM NaCl treatment. On the other hand, the expression of CmADH2 and Dof3 showed more fold change at 50 mM NaCl treatment. Finally, according to adaptation mechanisms of melon genotypes, the study might help in selection and detection of the salt tolerant ones.
Determination of Genetic Diversity Among Cumra Melon Genotypes by Issr Markers
(Cukurova Univ, Fac Agriculture, 2012) Turkmen, O.; Sensoy, S.; Erdinc, C.; Paksoy, M.
The present study aimed to determine genetic relationships among 32 melon genotypes collected from Cumra-Konya by molecular markers. Thirty-six polymorphic ISSR markers obtained from 10 primers were used to define the genetic similarity among the melon genotypes by dendrograms or two and three dimensional scaling obtained from Simple Matching distance matrix. The computer program POPGENE was also used to calculate the statistical measures of genetic variation (Nei's gene diversity (H), Shannon's information index (I), and percentage of polymorphic loci). Based on the molecular Simple Matching distance matrix, the most similar genotypes were C15-C22 followed by C23-C26. Of all evaluated genotypes, the most distinct one was C28. The genetic variation estimates for melon genotypes in the present study were high (H = 0.27, I = 0.43 and 100 % polym).
Determination of Genetic Relations Among Tomato Accessions in Sulaymaniyah Region Through Issrs Markers Genetic Relations in Tomato Accessions
(Centenary University, 2020) Ibrahim, A.S.; Erdinc, C.
The goal of this study was to examine the genetic difference among thirty two tomato accessions (Solanum lycopersicum L.) grown in Sulaymaniyah using ISSR molecular markers technique. The results of ISSR markers revealed 65 amplified fragments, 50 of them were polymorphic from using 15 primers. Fifteen ISSR markers used to detect DNA polymorphism gave polymorphism percentage for each primer range between 50–100% with an average polymorphism percentage reaching 75.61%. ISSR6 and Sola 11 gave the highest polymorphism percentage was 100%, while 3F, Sola 5 and Sola 12 did not give any amplification. The mean of PIC (Polymorphic Information Content) value was 0.50 for ISSR markers. The similarity matrix was obtained by using Jaccard’s coefficients, based on polymorphic bands and dendrogram constituted through UPGMA cluster analysis. The dendrogram revealed 4 main groups. Genetic similarity (GS) ranged from 0.261 to 0.941 within studied accessions. The highest similarity was 0.941 for the genotype pairs G7 and G16. However, the lowest similarity index was 0.261 among G15-G24 and G15-G26. Tomato accessions were determined by two populations according to STRUCTURE analysis. The ISSR marker system ensured useful information in describing genetic diversity among tomato accessions collected from different geographical around Sulaymaniyah province. © 2020, Centenary University.

Determination of the Anthracnose (Colletotrichum Lindemuthianum (Sacc. and Magn.) Lambs. Scrib.) Resistance in Some Turkish Bean Genotypes by Artificial Inoculation and Molecular Methods
(Pakistan Agricultural Scientists Forum, 2017) Erdinc, C.; Turkmen, O.; Demir, S.; Sensoy, S.
A total of 123 bean genotypes collected from different regions of Turkey and 7 foreign anthracnose-resistant varieties were evaluated for resistance to anthracnose disease caused by the fungal pathogen Colletotrichum lindemuthianum (Sacc. and Magn.) Lambs. Scrib. Analysis was conducted using artificial inoculation as well as resistance-linked molecular markers. Artificial inoculation was performed in a growth chamber using Race 55. Molecular markers were obtained from SCAR [SAS13 (950 bp, Co-4(2)), SC08 (910 bp, Co-4), SF10 (1072 bp, Co-10), SZ04 (567 bp, Co-6)] and RAPD (OA18(1500) (1500 bp, Co-1(5)) primers associated with resistant genes. Results of artificial inoculation showed that in addition to the 7 foreign varieties, 21 Turkish bean genotypes were anthracnose-resistant, while the remaining 102 Turkish genotypes were not. Moreover, results of molecular-marker screening indicated the presence of one or more amplicons associated with resistant-gene markers (Co-4(2), Co-4, Co-6, Co-10 and Co-1(5)) in the majority of resistant genotypes. Only one accession (G89) had all 5 amplicons, and 6 accessions (G19, G20, G34, G93, G97 and Jaguar) had no amplicons. The present study discovered Turkish bean germplasm of both Andean and Mesoamerican source to have a high level of resistance against anthracnose Race 55. In addition, amplicons connected with several resistance genes were found in this broad bean germplasm. Bean genotypes distinguished in the present study as anthracnose resistant could be utilized in future reproducing programs.
Effects of Drought Stress on Plant Growth Parameters, Membrane Damage Index and Nutrient Content in Common Bean Genotypes
(Pakistan Agricultural Scientists Forum, 2017) Kabay, T.; Erdinc, C.; Sensoy, S.
Common bean (Phaseolus vulgaris L.) is an important crop in both Turkey and the world. Drought is one of the important abiotic stress factors limiting the quality and quantity of common bean. This study was conducted to determine the drought-tolerant and susceptible common bean genotypes in Lake Van Basin of Turkey. Total 48 bean genotypes consisted of 40 genotypes from Lake Van Basin, 6 from different parts of Turkey and 1 drought susceptible varietyZulbiye and 1 drought tolerant variety-Yakutiye. The drought experiment was designed as completely randomized plot with 4 replicates in plastic greenhouse conditions. The four-week-old bean seedlings were subjected to drought stress by completely stopping irrigation for 8 days compared to control seedlings. The investigated traits were growth rate, fresh and dry shoot weights, fresh and dry root weights, stem diameter, area and number of leaves, leaf relative water content (LRWC), membrane damage index (MDI), and ion contents (K, Ca and Na) beside the 0-5 visual scale assessment of drought. At the end of the study, it was determined that plant growth and development of the bean genotypes were negatively affected by drought; however, the studied bean genotypes reacted variously to this stress factors. The genotypes V7, V15, V33, V82, V89 and V-A1 were found to be drought sensitive as the variety Yakutiye, while the genotypes V21, V62, V69, V71, V86, V95 and T7 were found to be drought tolerant as the variety Zulbiye.

(Academic Journals, 2008) Turkmen, O.; Sensoy, S.; Demir, S.; Erdinc, C.
This study was carried out to determine the effects of different Arbuscular Mycorrhizal Fungi (AMF) species on the growth and nutrient contents of pepper seedlings (cv. Demre) grown under moderate salt stress. Two different mychorrhizas (Glomus intraradices and Gigaspora margarita) were tested on a growing media containing moderate salt stress (75 ppm NaCl). The study was replicated four times with 8 plants in each replicate. At the end of the study, some nutrients such as P, K, Ca, and Na and plant growth parameters such as shoot height, stem diameter, root length, and dry and fresh weights of shoots and roots were investigated. Saline condition had negative effects on the seedlings. Both AMF species had positive effects on salt tolerance based on the plant growth parameters and nutrient contents. G. intraradices caused better response in seedling development compared to G. margarita, though insignificantly.
Evolution of Common Beans Collected From Lake Van Basin for Their Resistance To the Common Bacterial Blight (Xanthomonas Axonopodis Pv. Phaseoli)
(Corvinus Univ Budapest, 2018) Erdinc, C.; Ekincialp, A.; Akkopru, A.; Yildiz, M.; Sensoy, S.
The present study determined the reactions of common bean landraces grown in Lake Van Basin of Turkey against common bacterial blight disease (CBB) caused by Xanthomonas axonopodis pv. phaseoli (Xap). For this purpose 83 bean landraces collected from the basin and two resistant (HR-45, HR-67) and one susceptible (Dresden) lines were evaluated for their reaction to Xap. The experiments were conducted in randomized experimental design with three replications in a growth chamber having 23 +/- 2 degrees C temperature and 16 h light-8 h dark period. Bean seeds were sown in the pots having 2: 1 mixture of peat: perlite and Xap inoculated by spraying when the seedlings reached two trifoliate leaves stage. Disease severity was assessed three weeks after Xph inoculation using 1-5 scale. In light of the findings, it was detected that there was a variation with regard to tolerance to the disease among common bean landraces. While fourteen landraces were assigned as resistant against CBB, 49 landraces were found to be moderately susceptible to CBB. The present study demonstrated the existence of resistance sources against CBB within Lake Van Basin bean landraces that could potentially be used for breeding resistant cultivars.

(Pakistan Agricultural Scientists Forum, 2017) Erdinc, C.; Turkmen, O.; Dasgan, H. Y.; Sensoy, S.
The genetic relationships among 96common Turkish bean (Phaseolus vulgaris L.) genotypes were investigated based on72 phenotypic characters and molecular ISSR and RAPD markers. Main seed color and predominant secondary seed color were determined as the primary characteristics to distinguish the bean accessions. The mentioned traits, among 72 individual phenotypic traits, explained 58.46 % of phenotypic variation in the first three axes of the principal component analysis (PCA) beside flower duration, plant height, and a number of nodes on the stem. The 21 ISSR primers and 8 RAPD primers having clear and readable band data were also employed, 358 and 116 polymorphic bands were obtained from them, respectively. Polymorphism information content value for ISSR varied between 0.15 and 0.50, while that for RAPD was from 0.31 to 0.48. Among the examined genotypes, molecular genetic relationship determined based on dendrogram obtained by Jaccard distance matrix. Based on the results, the 52% and 48% of the bean genotypes were categorized as Mesoamerican and Andean originated genotypes. In addition, genetic variation values were determined by using Nei and Shannon coefficients and they were highly variable among bean genotypes.

(Pakistan Agricultural Scientists Forum, 2011) Sensoy, S.; Demir, S.; Tufenkci, S.; Erdinc, C.; Demirer, E.; Unsal, H.; Ekincialp, A.
Four zucchini hybrids (Focus F-1, Comet F-1, Natali F-1, and Ezra F-1) inoculated by three different arbuscular mycorrhizal fungi (AMF) [Glomus intraradices (Gi), Glomus etinucatum (Ge), and Gigaspora margarita (Gm)] in a growth chamber experiment were evaluated for seedling traits, nutrient uptake, colonization, and relative mycorrhizal dependency (RMD). Relative mycorrhizal dependency ranged widely among four zucchini hybrids. Gm inoculations had higher positive RMDs, while Gi inoculations had lower negative RMDs. Gm-inoculated Focus F-1 had the highest RMD (30.22%). Arbuscular mycorrhizal fungi inoculated seedlings had wider cotyledons and stems. There were also significant effects of AMF inoculation on the most of nutrients.
Sustainable Horticulture: Microbial Inoculants and Stress Interaction
(Elsevier, 2022) Seymen, M.; Kurtar, E.S.; Erdinc, C.; Kumar, A.
Sustainable Horticulture: Microbial Inoculants and Stress Interaction gives insights into the applications and formulations of microbial inoculants. In recent years, the optimum yields of horticultural plants largely influenced by rising global temperature, biotic stress (attack of pathogens) and abiotic stresses has created extra pressure for the horticulturalist to meet the need of optimum yield production for the burgeoning global population. However, the challenges of biotic and abiotic stress factors mitigated by traditional physical or chemicals methods include high application cost and adverse impact on quality limit the frequent use, hence the solutions in this book create new avenues for progress. This book covers those challenges and how microbial based bio inoculants are broadly used in horticulture to mitigate the challenges of biotic and abiotic stresses. It provides an important contribution on how to apply efficient beneficial microbes (microbial inoculants) for a sustainable society. © 2022 Elsevier Inc. All rights reserved.
