These changes appear to controlled by multiple signal transduction pathways. We hope to discern the mechanisms that are involved in positive and negative selection of mRNAs for translation under stress conditions. We are also studying the structure and function of plant ribosomes. P3 is an evolutionarily distinct component of this complex found in higher plants. Our results indicate that ribosomes are heterogeneous with respect to the levels of these proteins.
Current studies address the biological significance of ribosomal heterogeneity.
