Successful gall induction by Diplolepis rosae and D. mayri on the sweet briar (Rosa rubiginosa) under laboratory conditions

Abstract

O_LIPlant galls are unique outgrowths caused by various organisms, including insects, serving as nourishment for the inducers larvae. Despite the taxonomists and ecologists attempts to elucidate the mechanisms behind plant gall formation, its understanding is still incomplete. Modern genetic techniques allow in depth analysis of the molecular processes, but variations across species entangle the analysis. Establishing laboratory-friendly plant-gall inducer communities is crucial, yet past attempts have faced challenges. C_LIO_LIOur study aimed to create a sustainable laboratory community involving wild roses (Rosa sp.) and as gall-inducing insects rose gall wasps belonging to the genus Diplolepis. Controlled indoor conditions were optimized for plant growth. Wild roses were transplanted, then exposed to gall inducers, and monitored. C_LIO_LISuccessfully initialized gall growth was measures and analysed, revealing insights into the impact of plant vigour on gall size. C_LIO_LIOur study successfully established a novel laboratory community for further research on gall formation mechanisms. C_LI
