Comparative phenotypic, physiological, and transcriptomic responses to drought and recovery in two Fraxinus species.

ABSTRACT:

Background

This study focused on the drought tolerance and resilience of two ash species: Fraxinus chiisanensis and F. rhynchophylla. These two species are distributed in different habitats, suggesting that they have different levels of drought tolerance. Understanding their response to drought stress, particularly during the seedling stage, is crucial for selecting and developing drought-resistant varieties. This study aimed to compare the phenotypic, physiological, and transcriptomic characteristics of drought-stressed and recovered rewatered plants in a time-course experiment.

Results

In F. rhynchophylla, drought stress resulted in more severe growth retardation, temperature increase, and a faster decline in the fluorescence response, accompanied by a significant rise in
