Project description:Diapause is an environmentally programmed and hormonally regulated period of dormancy which makes an important part of the life-cycle in many species of invertebrates. In this study, using a RNAseq approach, we focused on very early stages of diapause induction in the larvae of drosophilid fly, Chymomyza costata by characterizing global patterns of gene expression associated with photoperiodic induction of diapause.
