Up-Regulated Salivary Proteins of Brown Marmorated Stink Bug Halyomorpha halys on Plant Growth-Promoting Rhizobacteria-Treated Plants

چکیده
Plant Growth-Promoting Rhizobacteria (PGPR) induce systemic resistance (SR) in plants, decreasing the development of phytopathogens. The FZB42 strain Bacillus velezensis is known to an SR against pathogens various plant species. Previous studies suggested that it could also influence interactions between plants and associated pests. However, insects have developed several strategies counteract defenses, including salivary proteins allow insect escaping detection, manipulating defensive pathways its advantage, deactivating early signaling processes, or detoxifying secondary metabolites. Because Brown Marmorated Stink Bug (BMSB) Halyomorpha halys highly invasive polyphagous, we hypothesized detect PGPR-induced defenses plant, efficiently adapt compounds them. Therefore, inoculated a beneficial rhizobacterium on Vicia faba roots soil, previous infestation with BMSB. Salivary gland proteome BMSB was analyzed by LC–MS/MS label-free quantitative proteomic method. Among differentially expressed proteins, most were up-regulated glands exposed PGPR-treated for 24 h. We confirm confronted stress during feeding plants. to-be-confirmed state would been rapidly detected H. pest, which consequently modified proteins. many be role defense counteraction, more especially allelochemicals detoxification sequestration.
