Expression and function of two olfactory-related genes in response to methyl salicylate in the wolf spider Pardosa pseudoannulata (Araneae: Lycosidae)
Expression and function of two olfactory-related genes in response to methyl salicylate in the wolf spider Pardosa pseudoannulata (Araneae: Lycosidae)
Expression and function of two olfactory-related genes in response to methyl salicylate in the wolf spider Pardosa pseudoannulata (Araneae: Lycosidae) The wolf spider ( Pardosa pseudoannulata ) is common in rice fields. Olfaction is crucial for perceiving chemical information, and our previous research indicated that methyl salicylate (MeSA), a common herbivore-induced plant volatile (HIPV), significantly attracts P. pseudoannulata . However, few studies have examined the functions of spiders' olfactory-related genes and their interactions with HIPVs. This study aimed to identify olfactory-related genes associated with MeSA in P. pseudoannulata . Transcriptome analysis revealed four differentially expressed olfactory-related genes in response to MeSA in P. pseudoannulata . Subsequent molecular docking analysis indicated that MeSA had a strong predicted binding affinity with proteins of two key olfactory-related genes ( PpseNPC2-7 and PpseSNMP2 ). These two genes were cloned, and...
