The rice Os08g0345800 was reported as OsAPS2 in 2005 [1] by researchers from Japan.
Contents
Annotated Information
Figure 3. Expression of rice AGPases in leaves, stems and roots during light/dark periods.[1].
Gene Symbol
- Os08g0345800 <=> OsAPS2,APS2
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.
Mutation
Expression
- OsAPS2 was constitutively expressed and these isoforms were coordinated with starch accumulation in the developing rice seed.
- 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.
