Abstract
The soluble proteins of germinated embryos and young shoots in Wheat were studied by means of isoelectrofocusing (IEF) electrophoresis. The materials used were three species of cytoplasmic male-sterile (CMS) lines (Type E, T and A) and their maintainers. The protein quantity of pI 4. 9 in male-fertile materials is higher than the corresponding male-sterile ones; the protein of pI 6.85 is probably the result of gene expression in Timopheevi cytoplasm; the protein of pI 7.6 is a typical band of Jinfeng male-sterile line. Evident differences on soluble protein chromatograms of IEF electrophoresis were observed both in germinated embryos and young shoots which were from different kinds of CMS line, these differences could be used as indexes identifying various CMS lines.
