The rice gene Os06g0625400 was reported as spp in 2010[1] by researchers from China.

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.

Evolution

You can also add sub-section(s) at will.
