摘要
Crude toxin of Rhizoctonia solani(RS-toxin) caused obvious damage to the cell of rice.The permeability of cell membrane changed and phosphorous permeated exterior when the sheath and leaves were treated with RS-toxin.After 12 hours treated with RS-toxin,chloroplast membrane was damaged and lamella was relaxed and swollen,with some cavities in the chloroplast.Treated with RS-toxin for 36 hours,the chloroplast was disassembled,other organelles became unclear and disappeared such as mitochondria,and some parts of the cell wall thinned and loosed.Treated with 10 times diluted RS-toxin,the chlorophyll content in the rice plants was reduced over 85%.With higher RS-toxin concentration and longer treatment time,the lower the chlorophyll content became.
Crude toxin of Rhizoctonia solani （RS-toxin） caused obvious damage to the cell of rice. The permeability of cell membrane changed and phosphorous permeated exterior when the sheath and leaves were treated with RS-toxin. After 12 hours treated with RS-toxin, chloroplast membrane was damaged and lamella was relaxed and swollen, with some cavities in the chloroplast. Treated with RS-toxin for 36 hours, the chloroplast was disassembled, other organelles became unclear and disappeared such as mitochondria, and some parts of the cell wall thinned and loosed. Treated with 10 times diluted RS-toxin, the chlorophyll content in the rice plants was reduced over 85%. With higher RS-toxin concentration and longer treatment time, the lower the chlorophyll content became.
