Gene Details:

• MSU gene ID: LOC_Os02g10900
• RAPdb gene ID: Os02g0203500
• Gene Symbol: RLS1 NOE2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Consistent with its involvement in leaf senescence, RLS1 was up-regulated during dark-induced leaf senescence and down-regulated by cytokinin.
• In this study, the genetic and physiological characteristics of the rice RLS1 (rapid leaf senescence 1) mutant were identified.
• The rapid loss of chlorophyll content during senescence was the main cause of accelerated leaf senescence in RLS1.
• Intriguingly, constitutive expression of RLS1 also slightly accelerated leaf senescence with decreased chlorophyll content in transgenic rice plants.
• A novel protein RLS1 with NB-ARM domains is involved in chloroplast degradation during leaf senescence in rice.
• The RLS1 mutant developed small, yellow-brown lesions resembling disease scattered over the whole surfaces of leaves that displayed earlier senescence than those of wild-type plants.
• Microscopic observation indicated that PCD was misregulated, probably resulting in the accelerated degradation of chloroplasts in RLS1 leaves.
• A screen for suppressors of RLS1 activation identified RMC (Root Meander Curling) as essential for the RLS1-activated defense response.
• An activated form of NB-ARC protein RLS1 functions with cysteine-rich receptor-like protein RMC to trigger cell death in rice.
