Gene Details:

• MSU gene ID: LOC_Os05g02020
• RAPdb gene ID: Os05g0110900
• Gene Symbol: OsRLCK176 BML
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Here, we demonstrate that the rice LysM receptor-like kinase OsCERK1, a key component of the chitin elicitor signaling pathway, also plays an important role in PGN-triggered immunity in rice.
• BML is a candidate gene associated with leaf senescence, ROS regulation, and disease response, also involved in hormone signaling in rice.
• The BML mutant showed excessive accumulation of reactive oxygen species (ROS), increased activities of superoxide dismutase, catalase, and malondialdehyde, upregulation of senescence-induced STAY-GREEN genes and senescence-related transcription factors, and down regulation of photosynthesis-related genes.
• The BML mutants had brown midribs in their leaves and initiated senescence prematurely, at the onset of heading.
• In pathogen response, BML demonstrated higher resistance against Xanthomonas oryzae pv.
• A map-based cloning using insertion/deletion markers confirmed that BML was located in the 57.
• The levels of abscisic acid (ABA) and jasmonic acid (JA) were increased in BML with the upregulation of some ABA and JA biosynthetic genes.
