De novo assembly of Amorpha fruticosa L. transcriptome in response to drought stress provides insight into the tolerance mechanisms
Background Amorpha fruticosa L. is a deciduous shrub that is native to North America and has been introduced to China as an ornamental plant. In order to clarify the drought resistance characteristics of Amorpha fruticosa L. and excavate the related genes involved in drought resistance regulation pa...
