GCR2

GCR2, also known as SGT1 or HSGT1, primarily found in plant cells, is a G protein-coupled receptor that is particularly studied in model plants like Arabidopsis thaliana. This receptor is crucial for binding to N-acyl homoserine lactones, especially 3OC6-HSL, which are produced by bacteria. By engaging the G protein signaling pathway, GCR2 helps transmit these signals, influencing plant gene expression and cellular responses. Research into GCR2 sheds light on the complex communication between plants and bacteria, suggesting that manipulating GCR2 could improve crop resistance to diseases and environmental stress, potentially leading to the cultivation of hardier crop varieties.
