Impacts of altered RNA metabolism on abscisic acid signaling.
The plant hormone abscisic acid (ABA) regulates many essential processes in growth and development. The recent characterization of ABA-sensitivity mutations in RNA-binding proteins has led to the recognition of a functional link between post-transcriptional mRNA processing and the ABA signal transduction machinery. By influencing transcript abundance, these RNA-binding proteins may modulate ABA signaling through the alteration of mRNA processing events such as splicing, 3' processing, nuclear export, transcript stability and RNA degradation.
