主 题:cell death Riptortus pedestris salivary proteins soybean staygreen
摘 要:Riptortus pedestris(Fabricius),one of the major piercing-sucking insects in soybeans,causes delayed plant senescence and abnormal pods,known as staygreen *** research has shown that direct feeding of this insect is the major cause of soybean staygreen ***,it remains unclear whether *** salivary proteins play vital roles in insect ***,we found that 4 secretory salivary proteins can induce cell death in Nicotiana benthamiana by transient heterologous *** cell death induced by Rp2155 relies on the nucleotide-binding leucine-rich repeat helper,***-specificity assays indicated that Rp2155 is specifically expressed in the salivary gland of *** and is significantly induced during insect *** expression of salicylic acid(SA)-,jasmonic acid(JA)-related genes was increased in soybean when fed by Rp2155-silenced *** importantly,soybean staygreen symptoms caused by *** were significantly alleviated when Rp2155 was ***,these results suggest that the salivary effector Rp2155 is involved in promoting insect infestation by suppressing the JA and SA pathways,and it can be considered as a potential RNA interference target for insect control.
