Aminoisothiazolamides, a new class of potent inhibitors of lysyl‐tRNA synthetase

Pest Management Science, Volume 81, Issue 7, Page 3956-3983, July 2025.
The present work covers a series of novel herbicidal lead structures that possess an aminoisothiazolamide scaffold as a structural key feature. Lysyl‐tRNA synthetase 1 (KRS1) was identified as the biochemical mode‐of‐action. Based on optimized and tailored synthetic approaches, a broader SAR study was carried out delivering some lead structures that ...

Nutritive value of unconventional fibrous ingredients fed to Guinea pigs in the Democratic Republic of Congo [PDF]

, 2009
peer reviewedThe energy and protein value for Guinea pigs (GP) of 9 forages (7 dicots and 2 grasses) and 5 hay-based diets was determined. The apparent faecal digestibility of dry matter, organic matter, crude protein and energy was measured on GP housed

Tracing the biogeographic history of the world's most isolated insular floras

Journal of Systematics and Evolution, Volume 63, Issue 4, Page 952-973, July 2025.
We inferred the spatio–temporal colonization histories of seven vascular plant lineages (Acaena magellanica, Austroblechnum penna‐marina, Azorella selago, Colobanthus kerguelensis, Notogrammitis crassior, Polystichum marionense, Pringlea antiscorbutica) using phylogenetic, divergence time estimation, and Bayesian Island Biogeographic analyses.

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.
