Resistance to protoporphyrinogen oxidase inhibitor herbicides in giant ragweed (Ambrosia trifida) is associated with a novel R98Q target-site mutation in PPO2

Cristiana Bernardi Rankrape, Isabel Schlegel Werle, Eduardo Lago…·Karla L. Gage

This study identifies a novel R98Q mutation in PPO2 as the target-site resistance mechanism for PPO-inhibitor herbicides in giant ragweed population VRC, while TMS shows resistance without target-site alteration.

Chromosome-level assemblies of Amaranthus palmeri, Amaranthus retroflexus, and Amaranthus hybridus allow for genomic comparisons and identification of a sex-determining region

Damilola A. Raiyemo, Jacob S. Montgomery, Luan Cutti…·Patrick J. Tranel

The paper presents chromosome-level genomes of three Amaranthus species, identifies a male-specific region, and characterizes genes and eccDNA related to sex determination and herbicide resistance.
