Updated project metadata. In this study, liquid chromatography-tandem spectrometry (LC–MS/MS) analysis was conducted to characterize the overall salivary protein composition from dissected salivary glands and secreted saliva in P. bambucicola, and to identify putative effector proteins important for aphid-plant interactions. This study promotes our understanding for the role of salivary glands in host specialization of P. bambucicola, and provide insight into its adaptation to unique feeding habit.
