Abstract
In this study,the experimental systems of rice suspension cells and calli were established.The resistant mechanisms to Magnaporthe grisea were investigated using the systems.The results showed that the xylanase treatment induced rapid accumulation of H2O2 and in rice suspension cells.Both xylanase and the extract from M.grisea induced the expression of defense genes Cht-1 and PR10.The expression of Cht-1 was induced obviously in suspension cells after 1 h treatment while the expression of PR10 was induced after 12 h treatment.Both xylanase and the extract from M.grisea induced the synthesis of sakuranetin,a major phytoalexin induced by blast infection.In addition,when the calli were treated with either xylanase or the extract from M.grisea,their color turned to brown,and their fresh weight and density decreased.The results indicate that suspension cells and callus are convenient and suitable plant materials for studying the mechanisms of the resistance to M.grisea in rice.
