Effects 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 کاملThe 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 کاملPlant-Induced Hatching of Eggs of the Soybean Cyst Nematode Heterodera glycines.
Root diffusate from soybean plants caused greater hatching of Heterodera glycines eggs during vegetative growth of the host, but the activity declined with plant senescence. Chelation of the root diffusate with ethylenediamine tetraacetic acid (EDTA) significantly increased hatching activity for H. glycines eggs. Diffusate from leafless plants caused little hatching, whereas treatment of intact...
متن کاملNematode Population Attrition and Histopathology of Heterodera glycines-Soybean Associations.
Selected populations of soybean cyst nematodes were inoculated to roots of compatible and incompatible soybeans. Rates of penetration of infective juveniles of nematode populations selected on PI 209332, PI 89772, and Pickett 71 were equivalent on compatible and incompatible soybean roots. The first two populations averaged about 10% and the last about 5% penetration in 24-hour inoculations of ...
