Fractions of nucleic acids in seedlings and leaves of winter wheat in the vegetative and generative development phases

W. Filek

Abstract


The composition of nucleic acid preparations isolated from seedlings and leaves of plants grown from vernalized and nonvernalized winter wheat grain was chromatographically investigated on a methylated albumin kieselguhr column (MAK column). The intensity of synthesis of the particular nucleic acid fractions was compared by the 32P-incorporation technique and the nucleotide composition of the newly synthesized nucleic acid fractions was determined. It was observed that the rate of 32P incorporation into the sRNA, rRNA+mRNA and TB-RNA fractions of the leaves of vernalized plants was about two times higher as compared with that in the nonvernalized control.
