Gene Symbol
- Os09g0298200 <=> OsAPS1,APS1
Function
- OsAPS1 encodes a small subunit of ADP-glucose pyrophosphorylase (AGPase).
- AGPase catalyzes the conversion of glucose (Glc)-1-phosphate and ATP to ADP-glucose and pyrophosphate.
Expression
- OsAPS1 was expressed later in seed development.
- In order to clarify the effect of sugars and plant hormones on AGPase gene expression more precisely, a rice cell culture system was used.
- OsAPL3 transcript significantly accumulated in response to increased levels of sucrose and abscisic acid (ABA) concentration in the medium; however, the transcripts of other AGPase genes did not show significant accumulation.
Subcellular localization
- Based on the alignment analysis (Fig. 1) and subcellular localizations as predicted by programs (PSORT, ChloP, TargetP and iPSORT), OsAPS2, OsAPL2 and OsAPL3 are extra-plastidial forms and OsAPS1, OsAPL1 and OsAPL2 are plastidial forms of AGPase.
