Messenger RNA —Conserved, Synthesized, or Both

One of the most disputed issues concerning protein synthesis in the newly-imbibed seed is whether or not prior RNA synthesis, particularly messenger 

The addition of a sequence of polyadenylic acid residues (poly A) to newly synthesized mRNAs appears to be a necessary step for their activation prior 

At the present time we do not know why mRNAs should be stored in seeds for later utilization during imbibition, germination and growth. It is possible that in the embryo storage makes them readily available for protein synthesis
