The rice Os11g0148500 was reported as OsPK1 in 2013 [1] by researchers from China.
Contents
Annotated Information
Gene Symbol
- Os11g0148500 <=> OsPK1,PK1
Function
- ospk1 may undergo certain stress, especially oxidative stress.
- The downregulation of OsPK1 (a cytosolic pyruvate kinase) in ospk1 mutant results in variations in ABA/GA balance in rice and contributes to oxidative stress, which provide a new clue for understanding the connection of pyruvate kinase, ABA/GA balance, and oxidative stress in rice.
Mutation
- In ospk1, a dwarf rice mutant, the contents of ABA in the youngest leaf sheaths of 6-week-old seedlings and the uppermost internodes of heading stage plants were both increased, and the synthesis of bioactive GAs was suppressed, which may disharmonize ABA/GA balance. In ospk1, expression of three putative enzyme genes related to stress response was upregulated.
- A strong browning symptom was observed in the second internode (Int2, counted from the top) and part of panicles of ospk1 at the late productive phase. Furthermore, higher levels of H2O2 in flag leaf and Int2 were observed in ospk1 than those in wild type.
