Project description:We collected samples of Pistil, Plain Valve, Plain lip and Plain calyx from the same period and quenched them in liquid nitrogen. Two biological replications were performed in each sample. TMT labeled quantitative proteomics was used to analyze different proteins in different tissues. GO and KEGG were used to analyze the differentially expressed proteins in different tissues, and the key proteins in the important pathway were found
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:Butterfly wing patterns are an important model for studying the genetic basis of morphological evolution. Here we used RNA-seq expression profiling in the butterfly Vanessa cardui to characterize the transcriptional basis of wing pigmentation. This approach identified numerous candidate genes including known and suspected components of the insect melanin and ommochrome biosynthetic pathways.
