The Effect of Magnaporthe Grisea Toxin on Photosystem in Rice

Abstract:

Understanding the toxic effect of Magnaporthe oryzae on rice to breed resistant varieties is important for environment protection. The effects of four M. Oryzae physiological races were conducted on the photosynthesis and photosynthetic pigment contents relating to hybrid rice. The results suggest that Pn、E、chl a/chl b and Car content at all growth stages, Ci and Gs at tillering stage, the content of Chl a, Chl b, Chl (a+b) at tillering stage and jointing stage are decreased significantly by the M. oryzae toxins , while Ci and Gs at jointing stage and booting stage, the content of Chl a, Chl b and Chl (a+b) at booting stage show a significant increase in their values. Photosynthesis of rice are inhibited by stomatal and non-stomatal factors in rice treated by M. Oryzae toxins. The response of rice at different growth stages is statistically different for various M. Oryzae physiological races.
