Abstract: | A gradual decrease in the total activity of DNA-dependent RNA polymerase in isolated wheat embryos began 6 hr after germination and continued for up to 48 hr. DEAE-cellulose column chromatography indicated the presence of two RNA polymerase fractions (major and minor) in the resting embryos, only one of which (major) could be detected in the embryos germinated for 48 hr. The major RNA polymerase fraction was tentatively identified as nucleoplasmic (RNA polymerase II). |
