mRNA Decay Machinery in Plants: Approaches and Potential Components
The abundance of a given mRNA is an important determinant of gene expression. This steady-state level is determined by a combination of the rates of synthesis and degradation of mRNA. Control at the level of message stability is of particular importance for genes whose expression is tightly regulated. Rapid degradation of transcripts in concert with transcriptional repression allows for the level of a transcript in the cytoplasm to be quickly diminished. This precise control of gene expression, afforded by rapid mRNA turnover, likely plays a significant role for plants, since as sessile organisms they must be able to quickly adapt to changes in the environment.
