Quantitative expression analysis of candidate genes for Septoria tritici blotch resistance in wheat (Triticum aestivum L.)
Septoria tritici blotch (STB), caused by the ascomycete fungus Mycosphaerella graminicola (asexual stage: Septoria tritici), is one of the most important foliar diseases of wheat. In this research, quantitative expression analysis of five candidate genes for the induction of resistance to STB (PR-1, Bsi, Msr, Per, and Ppi) was conducted in the wheat cultivars ‘Seri 82’ (susceptible) and ‘Fronta...
متن کاملResistance to Meloidogyne arenaria in Arachis spp. Germplasm.
Field and greenhouse evaluations of 116 wild Arachis spp. genotypes demonstrated the presence of resistance to reproduction of the root-knot nematode Meloidogyne arenaria race 1. Resistance in greenhouse tests was based on test lines having </= 2.5% of the number of eggs per gram of roots as did the susceptible A. hypogaea cv. Tamnut 74. In field tests, resistant genotypes were identified on th...
متن کاملEvaluation of Resistance to Zymoseptoria tritici Blotch andFusarium Head Blight in Some Genotypes of Bread Wheat
Using resistant cultivars is an effective method in management Zymoseptoria tritici Blotch and Fusarium Head Blight of wheat. This study was conducted to identify new sources of resistance to these diseases among a large number of Iranian cultivars and new wheat genotypes. The genotypes were cultivated in an augment design in the research farm of Aliabad Katoul Agricultural School. Artificial c...
متن کاملSpot Blotch, Net Blotch, and Stripe Disease of Barley
Spot blotch is caused by Helminthosporium sativum or H. sorokinianum = Drechslera sorokiniana (Bipolaris sorokiniana). The disease is widespread in Illinois and is believed to lower potential barley yields by 1 to 3 percent; also, the bushel weight. The causal fungus affects all parts of the plant and produces a variety of symptoms, from a seedling blight and root rot to “Black point” of the ke...
متن کاملFlowering Stage Resistance to Bacterial Fruit Blotch in the Watermelon Germplasm Collection
Cucurbit bacterial fruit blotch caused by Acidovorax avenae subsp. citrulli is a significant threat to watermelon [Citrullus lanatus (Thunb.) Matsum. and Nakai] production worldwide. In the United States, seedless cultivars are primarily used in watermelon production, which now relies largely on transplant production in greenhouses to ensure a high germination rate. Unfortunately, the warm and ...
