Os10g0567400
This gene locus named after OsCAO1 of Oryza sativa Japonica Group, whose length is 2983 bps and 541 amino acids ,plays a major role in chlorophyll b biosynthesis[1]

Annotated Information
Function
knockout mutant lines tagged by T-DNA or Tos17. Mutant plants containing a T-DNA insertion in the first intron of the OsCAO1 gene have pale green leaves, indicating chlorophyll b deficiency.These results suggest that OsCAO1 plays a major role in chlorophyll b biosynthesis
Expression
OsCAO1 is induced by light and is preferentially expressed in photosynthetic tissues.OsCAO1 was expressed strongly in shoots and leaves.
During the reproductive development stages, its expression level was higher in mature than in immature panicles.
When seedlings were grown under continuous light, they accumulated higher levels of OsCAO1 transcript than were measured in darkgrown plants.
Because the expression pattern of OsCAO1 was light-dependent, we examined whether its transcript level followed a circadian rhythm.Transcript levels
of OsCAO1 were higher during the daytime, but much lower in the late afternoon and at night.During the nighttime,OsCAO1 transcript levels were high.the change in expression for OsCAO1 was gradual, reaching a maximum level at 2 PM; its accumulation began in the dark.

Evolution
This class of proteins (chlorophyll a oxygenase (CAO) protein) they encode contain two conserved functional motifs – the Rieske Fe–sulfur coordinating center and a non-heme mononuclear Fe-binding site.
