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 کاملGenetic Relationships for Resistance to Heterodera glycines Races 3 and 5 in Soybean.
Heterodera glycines is the most damaging root pathogen of soybean in the United States. Plant introduction (PI) 90.763 is resistant to both races 3 and 5, whereas PI 424.595 is resistant only to race 5. Genetic relationships in these PI lines for resistance to H. glycines are not known. Crosses between PI 90.763 and PI 424.595 and susceptible cv. Essex were studied in the F, F, and F generation...
متن کاملGenetic Diversity for Resistance to Heterodera glycines Race 5 in Soybean.
Heterodera glycines is a serious pest of soybean in the United States. Plant introductions 90763 and 424595 are reported to be resistant to H. glycines race 5; however their genetic relationship for resistance is unknown. Crosses between these two lines and the susceptible cultivar Essex were studied in the F, F, and F generations to determine the number of genes involved in inheritance of resi...
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 کاملevaluation of some soybean lines to soybean cyst nematode (heterodera glycines) under control conditions and field
the soybean cyst nematode (heterodera glycine ichinohe, scn) is one of the most serious yields limiting pathogen on soybean (glycine max (l.) merr) which is found in many soybean–growing regions throughout the world. applying of resistant sources is one of the efficient measures to manage this nematode. in this study, reaction of 63 soybean lines to the soybean cyst nematode were evaluated in f...
