Changes of Template Activity and Proteins of Chromatin during Wheat Germination

RESUMO
Relationships between changes in template activity and composition of chromatin during germination of wheat embyros (Triticum aestivum L.) were investigated. The template activity of chromatin was determined with exogenous DNA-dependent RNA polymerase II (EC 2.7.7.6) prepared from wheat embryos. It was essentially constant for 18 hours of germination, corresponding to 2.5% of that of a native calf thymus DNA. Thereafter, the activity increased 2-fold and 5-fold at 24 and 60 hours of germination, respectively.
