The rice Os01g0839200 was reported as OsDSR2 in 2014 [1] by researchers from China and the USA.
Contents
Annotated Information
Gene Symbol
- Os01g0839200 <=> OsDSR2,DSR2
Function
- OsDSR2 encodes a protein with a DUF966 domain.
- Overexpression OsDSR2 in rice resulted in enhanced sensi- tivity to ABA-dependent salt and simulated drought stresses by downregulating the expression of multiple stress-responsive genes.
Phenotypic analysis
- In salt-containing medium, the shoot length, root number and fresh weight of transgenic seedlings were significantly less than that of WT seedlings. However, root length was not significantly different between transgenic and WT seedlings. In normal MS medium, there was no difference in these growth indicators between transgenic and WT seedlings. To further confirm transgenic plants’ sensitivities to salt stress, the transgenic plants of another line T12 were tested for salt response.
- After salt stress, transgenic plants exhibited significantly enhanced salt sensitivity. As expected, they displayed markedly lower survival rate compared with WT plants. These results suggested that the overexpression of the OsDSR2 could increase salt sensitivity of rice at the seedling stage.
Expression
- OsDSR2 was expressed mainly in nodes of stems and leaf blades from rice.
- Expression profile analysis of adversity showed that OsDSR2 had different transcriptional responses to salt, drought, cold, heat and oxidative (H2O2 ) stresses, as well as abscisic acid (ABA), methyl jasmonate, salicylic acid, gibberellin acid and auxin treatments.
Subcellular localization
- Subcellular localization analysis demonstrated that OsDSR2 was localized in the membrane and nucleus.
