Os03g0726100
The rice Os03g0726100 was reported as OsTubA1 and RiP-3 in 2000 and 2014, respectively [1] [2] by researchers from Republic of Korea and Canada.

Annotated Information
Figure 1. RNA gel blot showing the expression of RiP-3 gene in various parts of the panicle and the penultimate leaf of 6-week-old well-watered (control) and water-stressed rice plants.[1].
Function
- RiP-3 encodes a putative α-tubulin protein.
- The expression of α-tubulin gene may be part of the events that suppress panicle elongation during water deficit, which is in turn a suspected cause of male reproductive failure and yield reduction in rice.
Expression
- Expression of α-tubulin cDNA in various reproductive and vegetative organs of 6-week old well-watered and water-stressed rice plants was probed with RiP-3 cDNA. The cDNA hybridized to an expected 1.4 Kb transcript (Fig. 1).
- The highest expression was detected in ovaries, followed by rachis and glumes (lemma þ palea). No expression was detected in the penultimate leaf (the uppermost fully expanded leaf). Water stress suppressed α-tubulin expression in ovaries, rachis and bracts but promoted it in anthers (40%).
- Densitometric analysis showed that the greatest decrease in transcript level under water stress was in glumes (63%), followed by rachis (25%) and ovaries (12%).
