Polysomal and Post-polysomal RNA in Developing Barley Embryos and their Possible Role as Conserved Messages During Germination

Abstract

Sharp increase in post-poly somal RNA, accompanied by decrease in polysomal RNA from 24 days after anthesis to mature embryos, has indipated presence of conserved messages in mature embryos. Majority of these conserved messages were translated during 0 to 6 h germination stage, and a few others during 0 to 6 h stage. Both polysomal and post-poly somal RNA were more in Notch-2 than in NP 113, but conserved messages were translated to a greater extent in.NP 113.
