The rice gene Os06g0625400 was reported as spp in 2010[1] by researchers from China.
Contents
Annotated Information
Gene Symbol
- Os06g0625400 <=> spp, Osspp
Function
- SPP encodes a metalloendopeptidase that cleaves a broad range of precursor substrates.
- SPP is essential for chloroplast biogenesis at the early growth stage and for rice root development
Mutation
- spp mutant shows leaf chlorosis at the early seedling stage but inhibition of root growth during the whole growth period.
- The expression of some genes associated with chloroplast development was decreased in young seedlings of the spp mutant, but not in 14-day-old seedlings. Western blot analysis revealed that the Rubisco small subunit is not precisely processed in the spp mutant in 7-day-old seedlings, but the processing activity in the spp mutant is restored in 14-day-old seedlings.
- Moreover, the expression levels of Cab1R and Cab2R for the light-harvesting chlorophyll a / b -binding protein (LHCP) were highly up-regulated in the transgenic plants with overexpression of SPP.
Expression
Sublocalization
- Subcellular localization analysis indicates that SPP is targeted to the chloroplast.
