Hevea brasiliensis Transcriptome under cold stress
In this study, the cold resistant clone CATAS93-114 and sensitive Reken501 were subjected to cold stress, and their transcriptomes were analyzed at the timepoint of 0 h, 2 h, 8 h and 24 h. De novo transcriptome assembly and comparison were then carried out. The results showed that totally 7870 genes were differentially expressed. The resistant clone CATAS93-114 had more genes being evoked from 2 h to 8 h during cold treatment, indicating more rapid and intensive responsive profile than the sensitive clone Reken501. The DE genes can be further classified into seven major clusters, and GO terms in each cluster were enriched. The genes involved in ABA metabolism and signaling, ABA-independent pathway and early signal perception were noteworthy for their distinctive expression patterns toward cold stress between clones.
