Annotated Information

Gene Symbol

• Os01g0208700 <=> Osppc4

Function

• Osppc4 was expressedinallorganstestedandshowedhighexpressionintheleaves.

Expression

• Osppc4 was expressedinallorganstestedandshowedhighexpressionintheleaves.Its expression in the leaves was confined to mesophyll cells, and Osppc4 accounted for approximately one-third of total PEPC protein intheleafblade.

Mutant

• Knockdown of Osppc4 expression by the RNAi technique resulted in stunting at the vegetative stage, which was much more marked when rice plants were grown with ammonium than with nitrate as the nitrogen source.Comparisonofleafmetabolomesofammonium-grownplants suggested that the knockdown suppressed ammonium assimilation

and subsequent amino acid synthesis by reducing levels of organic acids, which are carbon skeleton donors for these processes.
