- Information
- Symbol: OsPORA
- MSU: LOC_Os04g58200
- RAPdb: Os04g0678700
- Publication
- NOA1 functions in a temperature-dependent manner to regulate chlorophyll biosynthesis and Rubisco formation in rice, 2011, PLoS One.
- The rice faded green leaf locus encodes protochlorophyllide oxidoreductase B and is essential for chlorophyll synthesis under high light conditions, 2013, Plant J.
- Two NADPH: Protochlorophyllide Oxidoreductase POR Isoforms Play Distinct Roles in Environmental Adaptation in Rice., 2017, Rice (N Y).
- Genbank accession number
- Key message
- OsPORA was expressed at high levels in developing leaves and decreased dramatically in fully mature leaves, whereas OsPORB expression was relatively constant throughout leaf development, similar to expression patterns of AtPORA and AtPORB in Arabidopsis
- Our results demonstrate that OsPORB is essential for maintaining light-dependent Chl synthesis throughout leaf development, especially under HL conditions, whereas OsPORA mainly functions in the early stages of leaf development
- OsPORA is expressed in the dark during early leaf development; OsPORB is expressed throughout leaf development regardless of light conditions
- The physiological function of OsPORB in response to constant light or during reproductive growth cannot be completely replaced by constitutive activity of OsPORA, although the biochemical functions of OsPORA and OsPORB are redundant
