Comparative Electrophoretic Analyses of Soluble Proteins from Heterodera glycines Races 1-4 and Three Other Heterodera Species
Modified polyacrylamide gel and SDS-polyacrylamide gel electrophoretic systems using a low molarity tris-HCl buffer and equal pH of homogenizing buffer and stacking gel provided improved stacking for separation of soluble proteins from Heterodera schachtii, H. trifolii, H. lespedezae, and H. glycine...

| Résumé: | Modified polyacrylamide gel and SDS-polyacrylamide gel electrophoretic systems using a low molarity tris-HCl buffer and equal pH of homogenizing buffer and stacking gel provided improved stacking for separation of soluble proteins from Heterodera schachtii, H. trifolii, H. lespedezae, and H. glycines races 1, 2, 3, and 4, compared with previous studies with cyst nematodes, The four Heterodera species were easily distinguished using the polyacrylamide gel system, but H. trifolii and H. lespedezae had similar protein patterns. H. glycines races were not separable by that system. The SDS-polyacrylamide gel system produced different protein patterns for all four Heterodera species although H. trifolii and H. lespedezae differed by only a single band, suggesting that these two may be subspecifically related. A protein band unique to H. glycines races 3 and 4 was not detected in SDS-polyacrylamide gel profiles from races 1 and 2. Molecular weight determinations were 55,000 for distinctive proteins in profiles of H. trifolii and 75,000 for H. glycines races 3 and 4 |
