Integrated transcriptomic and metabolomic analyses reveal critical gene regulatory network in response to drought stress in Dendrobium nobile Lindl.

ABSTRACT:

Background

Dendrobium nobile Lindl belongs to the genus Dendrobium of the orchid family and is a valuable herbal medicine. Drought stress severely affects the growth of D. nobile Lindl; however, the specific regulatory mechanisms have not yet been elucidated.

Results

In the present study, we conducted a combined transcriptome and metabolome analysis of D. nobile Lindl stems under different drought stress conditions. Global transcriptomic changes were detected in Dendrobium under different drought stress conditions. KEGG enrichment analysis showed that the DEGs were enriched in plant hormone signal transduction; cutin, suberin, and wax biosynthesis; starch and sucrose metabolism; and the biosynthesis of various plant secondary metabolites. The differentially abundant metaboli
