Physiological and transcriptome analysis reveals the mechanism of Gymnocarpos przewalskii response to drought stress.

ABSTRACT:

Background

Gymnocarpos przewalskii Bunge ex Maxim. (G. przewalskii) is an endangered xerophytic shrub that plays a crucial role as a source of forage in the Alxa Desert. However, there is limited understanding regarding the forage quality of G. przewalskii and its response to drought. This study aimed to evaluate the forage quality of G. przewalskii and investigate the physiological and transcriptomic changes in G. przewalskii response to drought stress.

Results

The ash, fat, crude protein, lignin, crude fiber, acid detergent fiber, and neutral detergent fiber contents in G. przewalskii twigs were 10.61%, 1.85%, 5.68%, 7.08%, 21.23%, 42.16%, and 58.42%, respectively. In contrast, these ingredients in its leaves were 20.39%, 0.92%, 11.96%, 2.40%, 17.51%, 14.29% and 20.26%, re
