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...

A new species of Ummidia Thorell, 1875, from Útila Island, Honduras (Araneae: Halonoproctidae)

Abstract

A new species of the charismatic mygalomorph genus Ummidia Thorell, 1875 is described from Utila Island, Honduras. Ummidia sukuhpaya sp. nov. represents the third species known from Honduras, and the first species known from Utila.
