POLYSOMAL AND POST-POLYSOMAL RNA IN DEVELOPING BARLEY EMBRYOS AND THEIR POSSIBLE ROLE AS CONSERVED MESSAGES DURING GERMINATION

Sharp increase in post-polysomal RNA, accompanied by decrease in polys omal RNA from 24 days after anthesis to mature embryos, has indicated presence of conserved messages in mature embryos. Majority of these co nserved messages were translated during 0 to 6 h germination stage, an d a few others during 30 to 36 h stage. Both polysomal and post-polyso mal RNA were more in Notch-2 than in NP 113, but conserved messages we re translated to a greater extent in NP 113.
