This dataset comprises mRNA that was extracted from Laternula elliptica developmental stages (blastula to juvenile) and sequenced (n=3 pools of 200 individual per stage). The resulting sequence data was analysed and the following results files and analysis scripts are available here: Results files from differential gene expression analysis in edgeR (edgeR_DE), results files from WGCNA analysis (WGCNA). Data collection was carried out over Hangar Cove Rothera Point, Adelaide Island, in Ryder Bay, from 2018-04-25 to 2018-09-25 by researchers with the British Antarctic Survey. The data was collected as part of research on the developmental biology of molluscs.
