PROTEOMIC ANALYSIS OF COWPEA APHID APHIS CRACCIVORA KOCH SALIVARY GLAND USING LC-MS/ MS ANALYSIS.

The present study identified 151 proteins from the salivary gland of cowpea aphid Aphis craccivora Koch, using LC-MS/MS analysis. These included enzymes mainly involved in the digestion and detoxification of secondary metabolites and proteins related to cell development and molecular function. Enzymes like peroxidase, trehalase, cytochrome P450 monooxygenase, glutathione peroxidase, esterase, peptidase, carboxypeptidase, maltase, and beta-galactosidase were prevalent in the proteome. Additionally, several proteins were assigned to cellular and molecular functions of salivary gland. These proteins may be involved in host-plant interactions. Comprehensively, these results provide a database for elucidating aphid-plant interactions at the molecular level in the future. [ABSTRACT FROM AUTHOR]
