The mitochondrial genome of the soybean cyst nematode, Heterodera glycines.
We sequenced the entire coding region of the mitochondrial genome of Heterodera glycines. The sequence obtained comprised 14.9 kb, with PCR evidence indicating that the entire genome comprised a single, circular molecule of approximately 21-22 kb. The genome is the most T-rich nematode mitochondrial genome reported to date, with T representing over half of all nucleotides on the coding strand. ...
متن کاملEffects of Rhizobacteria on Soybean Cyst Nematode, Heterodera glycines.
Rhizobacteria were isolated from the rhizoplane and rhizosphere of soybean plants from fields in Arkansas and tested for their effect on numbers of soybean cyst nematode (Heterodera glycines). In initial greenhouse tests in heat-treated silt loam soil, 138 of the 201 bacterial isolates tested had no influence on numbers of cysts and eggs + second-stage juveniles (J2) of H. glycines, 36 reduced ...
متن کاملAboveground Feeding by Soybean Aphid, Aphis glycines, Affects Soybean Cyst Nematode, Heterodera glycines, Reproduction Belowground
Heterodera glycines is a cyst nematode that causes significant lost soybean yield in the U.S. Recent studies observed the aphid Aphis glycines and H. glycines interacting via their shared host, soybean, Glycine max. A greenhouse experiment was conducted to discern the effect of A. glycines feeding on H. glycines reproduction. An H. glycines-susceptible cultivar, Kenwood 94, and a resistant cult...
متن کاملMolecular characterisation of two novel 17β-hydroxysteroid dehydrogenase genes from the soybean cyst nematode Heterodera glycines
Heterodera glycines Hg-hsd-1 and Hg-hsd-2 are two homologues of let-767, a short-chain dehydrogenase gene from the free-living nematode Caenorhabditis elegans. Both genes share similarity to 17β-hydroxysteroid dehydrogenases (17β-HSDs), enzymes known to be involved in the production of steroid hormones in mammals. Hg-hsd-1 and Hg-hsd-2 encode distinct protein sequences that share 51% amino acid...
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...
