Abstract
Polysomes and their associated ribonucleic acids were extracted from aging soybean cotyledons. Density gradient analysis showed that the ribosomes of older cotyledons were present largely as monosomes and light polysomes while younger cotyledons possessed a high proportion of heavy polysomes. Increased polysomal and mRNA activities were observed in 3- to 5-day-old and in 10-day-old cotyledons. The presence of polyadenylated mRNA was determined by oligo cellulose chromatography and confirmed by hybridization with 3H-polyuridylic acid.This publication has 8 references indexed in Scilit:
