Transgenic wheat development facility
The ICAR-IIWBR has a well managed tissue culture and transgenic development facility. A controlled environment glass house facility is also coming up for growing and studying transgenics under controlled condition. The availability of reproducible regeneration system through tissue culture is a major bottleneck in wheat improvement program. At ICAR-IIWBR an efficient regeneration and agrobacterium transformation system using mature and immature embryos as explants, in recently released spring wheat varieties (DBW 88, DBW 90, DBW 93, DPW 621-50, HD 3086 and WH 1105) were standardized. The optimized medium and method has resulted upto 100% regeneration, irrespective of the genotype used with high reproducibility. The wheat transformation system is giving upto 14% transformation efficiency. The functional validation of different abiotic stress responsive genes like NHX1, SHN1 and DREB genes are under progress.
