Transcriptome comparison reveals key candidate genes responsible for the unusual reblooming trait in tree peonies.

Tree peonies are important ornamental plants worldwide, but growing them can be frustrating due to their short and concentrated flowering period. Certain cultivars exhibit a reblooming trait that provides a valuable alternative for extending the flowering period. However, the genetic control of rebl...
