Evolution of drought resistance strategies following the introduction of white clover (Trifolium repens L.)

Background and Aims: Success during colonization likely depends on growing quickly and tolerating novel and stressful environmental conditions. However, rapid growth, stress avoidance, and stress tolerance are generally considered divergent physiological strategies.
 

Methods: We evaluate how white clover (Trifolium repens) has evolved to a divergent water regime following introduction to North America. We conduct RNAseq within a dry-down experiment utilizing accessions from low and high latitude populations from native and introduced ranges, and assess variation in dehydration avoidance (ability to avoid wilting) and dehydration tolerance (ability to survive wilting).
 

Key Results: Introduced populations are better at avoiding dehydration, but poorer at tolerating dehydration than native populations. There is a strong negative correlation between avoidance and tolerance traits and expression of most drought-associated genes exhibits similar tradeoffs.

This dataset contains a single .csv file (fileA.csv) that contains data on drought resistance phenotypes and metadata for 27 individuals within the reported dry-down experiment. The dry-down experiment was conducted on ~2 month old plants with the primary phenotypes of interest being the volumetric water content of soil at plant wilt and the survival following wilting. After wilting, plants were left for 48h before rehydration and survival was assessed after 72h. Further experimental details are provided in the parent paper: Hendrickson et al. 2025 (doi:10.1093/aob/mcaf037)
