• Publication
  • Differential regulation of chlorophyll a oxygenase genes in rice, 2005, Plant Mol Biol.
  • PGL, encoding chlorophyllide a oxygenase 1, impacts leaf senescence and indirectly affects grain yield and quality in rice., 2015, J Exp Bot.
• Genbank accession number
  • AK100517
• Key message
  • This study characterizes a rice mutant, pale green leaf (pgl), and isolates the gene PGL by using a map-based cloning approach
  • Compared with wild-type plants, pgl exhibits a lower Chl content with a reduced and disorderly thylakoid ultrastructure, which decreases the photosynthesis rate and results in reduced grain yield and quality
  • Moreover, pgl is sensitive to heat stress
  • In addition, pgl exhibits premature senescence in both natural and dark-induced conditions and more severe Chl degradation and reactive oxygen species accumulation than does the wild-type
• Connection
  • OsCAO1~PGL, OsCAO2, Differential regulation of chlorophyll a oxygenase genes in rice, We have identified two genes (OsCAO1 and OsCAO2) from the rice genome that are highly homologous to previously studied chlorophyll a oxygenase (CAO) genes
  • OsCAO1~PGL, OsCAO2, Differential regulation of chlorophyll a oxygenase genes in rice, These results suggest that OsCAO1 plays a major role in chlorophyll b biosynthesis, and that OsCAO2 may function in the dark
  • OsCAO1~PGL, OsPIL13~OsPIL1, Rice Phytochrome-Interacting Factor-Like1 OsPIL1 is involved in the promotion of chlorophyll biosynthesis through feed-forward regulatory loops., Using promoter binding and transactivation assays, we found that OsPIL1 binds to the promoters of two Chl biosynthetic genes, OsPORB and OsCAO1, and promotes their transcription
  • OsCAO1~PGL, OsPIL13~OsPIL1, Rice Phytochrome-Interacting Factor-Like1 OsPIL1 is involved in the promotion of chlorophyll biosynthesis through feed-forward regulatory loops., Thus, OsPIL1 is involved in the promotion of Chl biosynthesis by up-regulating the transcription of OsPORB and OsCAO1 via trifurcate feed-forward regulatory loops involving two OsGLKs
