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

High forage quality and drought stress tolerance were observed in G. przewalskii. In response to drought stress, G. przewalskii orchestrates reactive oxygen species scavenging, proline biosynthesis, and other intricate physiological processes, with substantial contributions from plant hormones and transcription factors. This study provides new insights into the forage quality and the mechanisms involved in drought adaptation of G. przewalskii, offering a foundation for its conservation and sustainable utilization.
