DEAD-Box RNA Helicases are among the onstituents of the Tobacco Pollen mRNA Storing Bodies

Male gametogenesis in flowering plants is attributed by substantial changes in cellular reorganization, cell fate specification and changes in cellular metabolism including RNA metabolism. Sequestration from immediate translation of protein coding mRNAs has emerged as one aspect of mRNA post transcriptional regulation that is widespread during gametogenesis. Transcripts repressed from translation are confiscated into mRNA storing bodies and function later during development and at early stages of embryogenesis. In Arabidopsis, 88% and 12% of the zygotic transcriptome at 2-4 cells stage of development now known to originate from maternal and paternal gametes respectively.
