Comparative transcriptomic analysis reveals differences in MADS-box genes of different hypericum in Changbai Mountains.

ABSTRACT: To explore the differences between the hypericum in the Changbai Mountains, we carried out a transcriptome analysis of two common hypericums in the area, which was Hypericum attenuatum Choisy and Hypericum longistylum Oliv. We screened the MADS-box genes to analyze divergence time and evolutionary selection expression, and determine their expression levels. The results showed that we detected 9287 differentially expressed genes in the two species, of which shared 6044 genes by the two species. Analysis of the selected MADS genes revealed that the species was in an environment adapted to its natural evolution. The divergence time estimation showed that the segregation of these genes in the two species was related to the changes of external environment and genome replication events. The results of relative expression showed that the later flowering period of Hypericum attenuatum Choisy was related to the higher expression of the SVP (SHORT VEGETATIVE PHASE) and the AGL12 (AGAMOUS LIKE 12), while the lower expression of the FUL (FRUITFULL).
