Gene Symbol
- Os04g0692600 <=> OsSGRL,SGRL
Function
- Overexpression of SGRL reduces the levels of Chl and Chl-binding proteins in leaves, and accelerates their degradation in dark-induced senescence leaves in rice.
- SGRL protein is involved in Chl degradation.
Expression
- Real-time Fluorescence Quantitative PCR analysis was used to investigate the patterns of SRGL expression in six tissues from rice plants: roots, stems, young leaves, senescent leaves, panicles and seeds. SGRL was strongly expressed in green tissues (leaves, stems and panicles), but less in nonphotosynthetic tissues (roots and seeds)
- The SGRL gene was strongly expressed during the transition from dark to light, but was less strongly expressed during the day. Conversely, SGR expression increased during the light period and peaked at noon.
Evolution
- The SGR and SGRL proteins share a highly conserved central region consisting of approximately 120 amino acid residues, but differ at both the N- and C-termini.
