Characterizing the causes and consequences of calcium oxalate crystal presence in Vitis riparia

American Journal of Botany, Volume 113, Issue 3, March 2026.
Abstract Premise Calcium oxalate biomineralization in plants is phylogenetically widespread and morphologically diverse, but the function of these inorganic crystals is an area of active debate. The variety of environmental conditions that produce the crystals, as well as the inconsistent evidence that they provide antiherbivore defense across plant ...

Impact of Pre‐Emergent Herbicides and Soil Management on Weed Community Dynamics and Soybean Yield

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Pre‐emergent herbicides are key tools in managing herbicide‐resistant and hard‐to‐control weed species in soybean (Glycine max L.) cultivation. This study aimed to evaluate the effects of pre‐emergent herbicides on weed phytosociology, soybean phytotoxicity, and grain yield under different soil management systems and environmental conditions.
