The rice Os03g0786400 was reported as DST in 2013 by researchers from China [1] .

Annotated Information
Figure S1. Phenotypic characterization of NIL DST REG1/reg1 plants[1].
Gene Symbol
- Os03g0786400 <=> DST, OsDST
Function
- The zinc finger transcription factor DROUGHT AND SALT TOLERANCE (DST) directly regulates OsCKX2 expression in the reproductive meristem.
- DST-directed expression of OsCKX2 regulates CK accumulation in the SAM and, therefore, controls the number of the reproductive organs.
- A semidominant allele of the DST gene, perturbs DST-directed regulation of OsCKX2 expression and elevates CK levels in the reproductive SAM, leading to increased meristem activity, enhanced panicle branching, and a consequent increase of grain number.
- DST is a unique regulator of reproductive meristem activity.
- DST may be explored to facilitate the genetic enhancement of grain production in rice and other small grain cereals[1] [2] [3] [4] [5] .
Phenotypic analysis
- DST reg1 Enhances Grain Production in both indica and jopanic Rice.
- All transgenic plants overexpressing a wild-type DST allele (DSTREG1) showed reduced plant stature with less panicle branches and decreased grain number.
- In contrast, the DST RNA interference (RNAi) transgenic plants showed increased panicle branches and enhanced grain number.
- Similarly, transgenic plants overexpressing the reg1 mutant allele of DST (DST reg1 ) had increased panicle branches and produced more grains.
Expression
- DST is located in the nucleus with transcriptional activation and it will express momentarily down under the condition of salt stress and osmotic stress, then recovered to pre-treatment levels.
