Herbicide Metabolic Resistance in Poaceae Plants via the GA-GID1/DELLA-DOF2-P450s Module. [PDF]
Adv Sci (Weinh)Plant hormone signaling modulates herbicide resistance in Echinochloa crus‐galli. The GA–DELLA–DOF2 cascade directly activates P450 detoxification genes in two Poaceae species, uncovering a core mechanism of metabolic herbicide resistance. ABSTRACT Barnyard grass (Echinochloa crus‐galli) is one of the world's most important weeds, and the evolution of ...

Effects of Meadow Connectivity on Plant Diversity in China's Poyang Lake: New Perspective of Effective Biodiversity Conservation. [PDF]
Ecol EvolHigher meadow connectivity leads to greater plant species richness but also increases plant community similarity. Functional connectivity explains plant diversity patterns better than structural connectivity. ABSTRACT The increasing global habitat fragmentation has led to a marked decline in landscape connectivity, posing a severe threat to ...

A Trp574-Leu substitution confers resistance to three classes of acetolactate synthase inhibitors in Australian brome grass (Bromus diandrus). [PDF]
Pest Manag SciTarget‐site based imidazolinone resistance in brome grass was found to be conferred by a mutation at position 574 in the ALS gene and to severely impact the efficacy of the herbicide Intervix®, a co‐formulation of imazamox and imazapyr. Abstract BACKGROUND Brome grass (Bromus diandrus) is a prevalent weed in southern Australian cropping regions which ...
