Clustering analysis of RNA-seq libraries and summary of global differential expression patterns. (A) A correlation heatmap was generated on the 60 RNA-seq libraries. High correlation between libraries are figured in white while low correlation across libraries by dark red colour: heads and embryos samples display very distinct expression profiles. (B) The number of DEGs between SD and LD photoperiod for each genotype and between the CP and the OP genotype within each photoperiod condition was calculated for each of the heads and embryos samples (FDR < 0.05 and Fold-Change > 1.5). The number of lncRNAs differentially expressed is indicated between brackets
