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 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 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 ...
متن کاملStructural 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 کاملCoating Soybean Seed with Oxamyl for Control of Heterodera glycines.
Oxamyl coated on soybean (Glycine max (L.) Merr. cv. Elgin) seeds in solutions of 20, 40, 80, and 160 mg/ml had no serious deleterious effects on seedling emergence and growth when planted in sterile soil. Seedling emergence on day 3 was less than that of the uncoated control, but by day 7 emergence was equal to, or greater than, the control. Shoot and root growth from seed coated with oxamyl i...
