Project description:An immobile pupal phase in butterfly metamorphosis is central for the production of an airborne adult from the earlier caterpillar feeding stage. Extensive body plan re-organization occurs within the pupal case that is entirely dependent upon nutrients accumulated during caterpillar growth, and sensitive to external environmental conditions. Here, we use DNA and RNA sequencing of a laboratory butterfly population to produce a time course dataset describing changes in DNA methylation and in the transcriptome during progression from the 5th instar caterpillar larval stage through to the latest stage of pupation when the mature butterfly is about to eclose from the pupal case.

Project description:To examine the repertoires of genes expressed in individual fru P1-expressing neurons, we performed single cell sequencing. The analysis was performed on male and female central nervous system tissues (48-hour pupal stage), from flies that expressed membrane-bound GFP in fru P1 neurons. We chose this developmental stage to gain further insight into how genes direct development of fru P1 neurons, as this is the stage where FruM has peak expression (in ~2,000 neurons).
Project description:Small RNA-seq was used to identify miRNAs in pupal stage Sarcophaga bullata and to assess differences in the abundance of miRNAs in developing and diapause (i.e. dormant) pupae.
