Structural Changes Associated with Resistance of Soybean to Heterodera glycines.
Subcellular responses to infection by Race 3 of Heterodera glycines in susceptible ('Lee') and resistant ('Forrest' and 'Bedford') soybean cultivars were compared. Syncytial formation, initiated in susceptible as well as resistant soybean cultivars, was characterized by wall perforations, dense cytoplasm, and increased endoplasmic reticulum, In susceptible plants, syncytia developed continuousl...
متن کاملTransgenic soybean overexpressing GmSAMT1 exhibits resistance to multiple‐HG types of soybean cyst nematode Heterodera glycines
Soybean (Glycine max (L.) Merr.) salicylic acid methyl transferase (GmSAMT1) catalyses the conversion of salicylic acid to methyl salicylate. Prior results showed that when GmSAMT1 was overexpressed in transgenic soybean hairy roots, resistance is conferred against soybean cyst nematode (SCN), Heterodera glycines Ichinohe. In this study, we produced transgenic soybean overexpressing GmSAMT1 and...
متن کاملstudy on inheritance of resistance to septoria tritici blotch in wheat by generation mean analysis
to study inheritance of resistance to septoria tritici blotch in wheat, the generation mean analysis method was used. so six generations (p1, p2, f1, f2, bc1 and bc2) were planted under completely randomized design with three replications in greenhouse. seedlings were inoculated at the second-leaf stage with an isolate of septoria tritici and necrosis and picnidia density and area under disease...

yellow, and even drop. Other symptoms of direct feeding damage include plant stunting, poor pod fill, reduced Since 2000, the soybean aphid (Aphis glycines Matsumura) has pod and seed counts, smaller seed size, and nutrient become a major pest of soybean [Glycine max (L.) Merr.] in North America. In the USA, there are currently no commercial soybean deficiencies resulting in overall yield and q...
متن کاملComparative analysis of soybean genotype resistance to Heterodera glycines and Meloidogyne species via resistance gene analogs.
Nematodes are important pests of soybean throughout the world and cause high yield losses. As a control strategy, the identification of resistance genes is an important aim of breeding studies. Plants possess resistance genes (R), which are responsible for the recognition of pathogens and activation of the defense system. R genes and resistance gene analogs (RGAs) possess conserved domains, fro...
