Antimicrobial potency of Euphorbia heterophylla against selected clinical isolates

open access: yesProceedings of the Nigerian Academy of Science, 2020
Reports on the antimicrobial potentials of Euphorbia heterophylla are scanty globally. This study investigated the antimicrobial effects of E. heterophylla against microorganisms of clinical importance. Cold water, hot water, chloroform and methanol extracts of the leaf, stem and fruit of E. heterophylla were obtained.

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

open access: yesFunctional 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.
