DOI: 10.1002/ps.6111
Abstract: BACKGROUND PPO inhibitors are important for the management of glyphosate- and ALS-resistant Palmer amaranth [Amaranthus palmeri (S.) Wats.]. The evolving resistance to PPO inhibitors is of great concern. We surveyed the evolution of resistance to… read more here.

Abstract: BACKGROUND Amaranthus palmeri S. Watson is a problematic weed infesting summer crops in Argentina and has developed multiple herbicide resistance. Resistance to acetolactate synthase (ALS)-inhibiting herbicides is particularly common, with high-level resistance mostly caused by… read more here.

DOI: 10.1021/acs.jafc.2c07162
Abstract: Commonalities in adaptive responses to abiotic stressors could contribute to the development of cross-resistance in weeds. The degree to which herbicide-induced changes in weeds parallel those induced by other abiotic stress remains unknown. We investigated… read more here.

DOI: 10.1021/acs.jafc.3c00196
Abstract: A Palmer amaranth (Amaranthus palmeri S. Wats.) biotype resistant to S-metolachlor was confirmed from crop fields in Arkansas, USA. This study investigated the metabolic effects of malathion (cytochrome P450 inhibitor) and 4-chloro-7-nitrobenzofurazan [NBD-Cl; glutathione S-transferase… read more here.

DOI: 10.3389/fmicb.2023.1114388
Abstract: Introduction Plant invasion can profoundly alter ecosystem processes driven by microorganisms. The fundamental mechanisms linking microbial communities, functional genes, and edaphic characteristics in invaded ecosystems are, nevertheless, poorly understood. Methods Here, soil microbial communities and… read more here.

DOI: 10.3390/plants12091886
Abstract: Weeds resistant to PPO-inhibiting herbicides threaten the profitability of crop producers relying on this chemistry. In Amaranthus palmeri, mutations at G210 (∆G210) and R128 (R128G/M) of the PPX2 gene were reported to confer PPO-inhibitor resistance.… read more here.
