News from IBE (CSIC-UPF)
Gene expression profiles across the different developmental stages in the wood white butterfly (Leptidea sinapis) have been compared with the aim of identifying key genes and pathways associated with diapause regulation. This species, which is distributed across western Eurasia, shows photoperiod-induced diapause with variation in critical day-length across populations at different latitudes.
The results of this international research, with the participation of Roger Vila, investigator at IBE, were published in Molecular Ecology. Expression differences between light treatment groups of two monoamine regulator genes (DDC and ST) were observed already in instar III larvae. -CS/PRBB
