The rice gene Os12g0631100 was reported as OsRab5B2 in 2010[1] by researchers from China.
Contents
Annotated Information
Gene Symbol
- Os12g0631100 <=> glup4(esp8), esp8, glup4, OsRab5B2, Rab5a, OsRab5a, gpa1, GPA1/Rab5a
Function
- The gene corresponding to the gpa1 mutation was found to be OsRab5a, which encodes a small GTPase.
- OsRab5a plays an essential role in trafficking of storage protein to PBII, possibly as part of its function in organizing the endomembrane system in developing endosperm cells of rice.
Mutation
- gpa1 mutant accumulates 57 kDa pro-glutelins in seeds and whose endosperm has a floury appearance.
- Transmission electron microscopy analysis showed that the gpa1 endosperm cells have an enlarged ER lumen and a smaller protein body II (PBII), and accumulated three types of newly generated subcellular structures. Moreover, a proportion of glutelins in the gpa1 endosperm cells were not delivered to PBII, and instead were mis-targeted to two of the newly generated structures or secreted.
Expression
- OsRab5a is widely expressed in rice plants. Quantitative RT-PCR analysis showed that the highest expression of OsRab5a occurs in roots.
Evolution
You can also add sub-section(s) at will.
