Gene Symbol
- Os05g0116100 <=> OsDHAR1,DHAR1
Function
- OsDHAR1 overexpression, capable of functioning in AsA recycling, and protein folding increases environmental adaptation to paddy field conditions by the improving AsA pool and redox homeostasis, which enhances rice grain yield and biomass.
Phenotypic analysis
- At the middle reproductive stage, OsDHAR1-expressing Transgenic (TG) rice plants (OX1, OX-2, and OX-3) displayed a better phenotype than WT rice plants (Fig. 3b).
- In addition, the total length of the TG rice plants was less than that of the WT rice plants, whereas the number of panicles of the TG rice plants was higher than that of the WT rice plants during vegetative growth (data not shown) and the harvest stages after flowering (Fig. 3c).
- As shown in Fig. 3d, most of the yield parameters, with the exception of 1,000 GW (TOGW), was increased in OsDHAR1-expressing TG rice plants (OX1 to OX-7) when compared with the WT rice plants.
