Variation in root hair traits in 75 xerophytic species: Constraints of phylogeny, trait trade‐offs and environment

Functional Ecology, Volume 39, Issue 6, Page 1594-1605, June 2025.
Abstract Root hairs play an important role in the acquisition of soil resources by increasing the absorptive surface area. Yet, key factors driving the variation of root hair traits across different species along biogeographic gradients are still poorly quantified, limiting our understanding of the functional relevance of root hairs.
