Of 4-hppd inhibitor resistance or sensitivity improved plant

By using 4-HPPD inhibitor sensitivity rice and 4-HPPD QTL analysis inhibitor-resistant rice, 4-HPPD inhibitors identified resistance gene is located on rice chromosome 2 short arm is estimated iron / ascorbate the dependent oxidoreductase gene (gene HISl). Further homologous genes also clear HIS1 gene (gene of HSL1) located on rice chromosome 6. Also we found that with these genes, can effectively create a resistance to 4-HPPD inhibitors or improve the sensitivity of the plant and sensitivity or resistance to a plant may be determined on the 4-HPPD inhibitors.
