Salt stress during germination degenerates crop establishment and declines yield in wheat (Triticum subsp.). Against salt (NaCl) stress, we investigated 12 bread (Triticum aestivum L.) and 10 einkorn wheat (T. monococcum subsp. monococcum) entries for germination rate, germinating power, coleoptile length, shoot length, root length, shoot/root length ratio, root fresh weight, root dry weight, and root fresh/dry weigh ratio. An effective blocking in variance analysis improved statistical significance and differentiation between germination stages and wheat entries. Salt total and salt ranking tolerance indices grouped the wheat entries into tolerant (Bayraktar 2000, Gerek 79, İkizce 96, Gün 91, Demir 2000, and …

Turkish Journal of Agriculture and Forestry
Numerous diseases caused by fungal pathogens influence the annual production of sugar beet. In order to obtain a plant resistant to fungi, genetic transformation has been applied to the sugar beet. To invade a plant tissue, phytopathogenic fungi produce several cell wall-degrading enzymes (CWDEs); polygalacturonases (PGs) are pathogenicity factors produced at the earlier stages of a fungal infection that depolymerize the homogalacturonan. One of the strategies used by plants to limit the degradation of the cell wall polysaccharides by fungal CWDEs is the production of proteinaceous inhibitors. Against fungal, microbial, and insect PGs, plants produce cell wall-associated polygalacturonase-inhibiting proteins (PGIPs). …

Identification And Functional Annotation Of Expressed Sequencetags Based Ssr Markers Of Stevia Rebaudiana, Rajinder Kaur, Neha Sharma, Ravinder Raina
Turkish Journal of Agriculture and Forestry
Stevia rebaudiana Bertoni, a perennial herb belonging to the family Asteraceae, is a tropical as well as subtropical plant of medicinal importance. Despite being an important medicinal plant and in fact proving a boon to diabetics, it has remained almost ignored by molecular biologists. A systematic molecular evaluation of stevia germplasm and molecular breeding work are sparsely reported mainly due to the limited specific molecular markers available. Expressed sequence tags (ESTs) are a valuable resource for developing simple sequence repeats (SSRs). In this study, 5548 stevia ESTs sequences from leaf tissues were retrieved from the NCBI database. Clustering and assembly …

Turkish Journal of Agriculture and Forestry
Lentil, which belongs to the family Leguminosae (Fabaceae), is a diploid (2n = 2x = 14 chromosomes) self-pollinating crop with a genome size of 4063 Mbp. Because of its nutritional importance and role in the fixation of nitrogen from the atmosphere, lentil is a widely used crop species in molecular genetic studies. By using DNA markers, to date, a limited number of polymorphic bands have been generated. Therefore, it is necessary to develop additional markers to saturate the genome at high density. Single nucleotide polymorphism (SNP) markers are promising for this purpose because of their abundance, stability, and heredity; they …

Evaluation Of Native Entomopathogenic Nematodes For The Control Of The European Cherry Fruit Fly Rhagoletis Cerasi L. (Diptera: Tephritidae) Larvae In Soil, İlker Kepenekci̇, Selçuk Hazir, Ayşe Özdem
Turkish Journal of Agriculture and Forestry
Turkey is the world's largest producer of sweet cherries. The European cherry fruit fly, Rhagoletis cerasi L. (Diptera: Tephritidae), is a major pest of sweet cherry crops in Europe and Turkey. The detection of only one larva in the fruit by the processor can result in the rejection of the entire crop of that orchard and/or farm as \"wormy\" and unmarketable. The main control tactic for R. cerasi is to prevent the females from laying eggs in the fruit. Currently, only a few insecticides are being used, and their application is debatable due to problems with residual ecotoxicity for humans …
