G proteins in plant .
Answers
Heterotrimeric G-proteins are involved in transducing extracellular signals from cell surface receptors into intracellular effectors. Although plants have only a small number of genes encoding the G-protein subunits, they have been implicated in a wide variety of biological processes.
Answer :
Heterotrimeric G-proteins play an important regulatory role in multiple physiological processes, including the plant immune response, and substantial progress has been made in elucidating the G-protein-mediated defense-signaling network. This mini-review discusses the importance of G-proteins in plant immunity. We also provide an overview of how G-proteins affect plant cell death and stomatal movement. Our recent studies demonstrated that G-proteins are involved in signal transduction and induction of stomatal closure and defense responses. We also discuss future directions for G-protein signaling studies involving plant immunity.
