主 题:Oral secretions Helicoverpa armigera Spodoptera litura Cotton Host plant defense
摘 要:Cotton(Gossypium hirsutum)is an important fiber crop *** attack causes cotton yield and quality ***,little is known about the mechanism of cotton response to insect *** simulated insect feeding by applying insect oral secretions(OS)to wounds,and combined transcriptome and metabolome analysis to investigate how OS from two major pest species(Helicoverpa armigera and Spodoptera litura)affect cotton defense *** found that respectively 12,668 and 13,379 genes were differentially expressed in comparison with wounding *** addition of OS,the jasmonic acid signaling pathway was rapidly and strongly induced,whereas genes involved in salicylic acid biosynthesis were *** constructing a coexpression gene network,we identified a hub gene encoding a leucine-rich repeat receptor kinase that may play an important role in early signal recognition and *** from the two insect species altered the abundance of flavonoid-related compounds in different *** remained in lower concentration after OS application than after wounding alone,suggesting a suppressive effect of OS on cotton defense *** study illustrated transcriptional and metabolic changes of cotton in responding to OS from two chewing insect species,identified potential key response genes,and revealed evidence for OS inhibition of wounding-induced cotton defense response.
