Characterization of Salivary Secreted Proteins That Induce Cell Death From Riptortus pedestris (Fabricius) and Their Roles in Insect-Plant Interactions.

ABSTRACT: Riptortus pedestris (Fabricius) is a polyphagous hemipteran crop pest that mainly feeds on the leguminous plants, resulting in shriveled and dimpled seeds. With recent several outbreaks in the Huang-Huai-Hai region of China, as well as in South Korea and Japan, this species has caused enormous economic losses to soybean crops. In the present study, we found that R. pedestris feeding results in local lesions at the infestation sites. To identify the key effectors that induce plant damage during feeding, the salivary glands of R. pedestris were dissected for transcriptome sequencing, and 200 putative secreted proteins were transiently expressed in N. benthamiana. Among them, three intracellular effectors (RP191, RP246, and RP302) and one apoplastic effector (RP309
