| Research Abstract |
The generating mechanism of herbicide responsive photon emission from cultured rice cells was analyzed. 50-100 ppm bensulfronmethyl (BSM) treatment induced an increment of photon emission from rice cells. Emission patterns of 18 tested herbicides were different from each other. CYP81A6, a cytochrome P450 gene reported to be responsible for BSM tolerance in rice, was isolated from the rice cells, and was silenced by RNAi. Responses of CYP81A6-silenced cell line to BSM and branched chain amino acids revealed that the BSM detoxifying reaction by cytochrome P450 is involved in BSM responsive photon emission from rice cells.
