Validation of the International Weed Genomics Consortium genome annotation pipeline through reannotation of the model species Arabidopsis thaliana

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract The International Weed Genomics Consortium (IWGC) has sequenced and annotated the genomes of over 30 weed species, generating genomic resources to understand their biology, evolution, and adaptation. The objective of this study was to evaluate the semi‐automated, isoform sequencing (Iso‐seq)‐based, IWGC genome annotation pipeline by ...

Genetic diversity and phylogenetic relationships among and within Amaranthus spp. using RAPD markers

Revista Mexicana de Biodiversidad, 2020
Random Amplified Polymorphic DNA (RAPD) markers were used to investigate genetic diversity and phylogenetic relationships among 10 species belonging to the genus Amaranthus L. The results showed that the polymorphism in cultivated species was lower than

Herbicidas orgánicos alternativa al glifosato para el control de maleza en presiembra en el norte de Tamaulipas

AIA Avances en Investigación Agropecuaria, 2022
Introducción. El manejo agronómico del cultivo desde siembra hasta cosecha es mecanizado. Uno de los componentes más importantes es el control de malezas (Montes et al., 2013). El manejo químico de las malezas se basa en un grupo de herbicidas sintéticos

Integrating developmental and macroevolutionary approaches reveals a staminodial origin of all alternisepalous organs in Caryophyllaceae

American Journal of Botany, Volume 113, Issue 8, August 2026.
Abstract Premise The identity of sterile floral organs in second‐whorl, alternisepalous positions within Caryophyllaceae remains contentious, having been described as staminodes, “petaloids,” or petals homologous with those of other Pentapetalae. Limited ingroup and outgroup sampling and floral developmental data and inadequate phylogenetic comparative

Palmer Amaranth (Amaranthus palmeri) Adaptation to US Midwest Agroecosystems

Frontiers in Agronomy, 2022
Palmer amaranth (Amaranthus palmeriS. Watson) is one of the most troublesome agronomic weed species in the United States. Palmer amaranth is prevalent in the Southern Great Plains and the Southeastern United States, and its range is expanding northward through natural dispersal and human intervention.

Analysis of glutamine synthetase target‐site mutations and their role in endowing glufosinate‐ammonium resistance

Pest Management Science, Volume 82, Issue 8, Page 7633-7644, August 2026.
GS2.2 G255D mutation conferred enzyme‐level glufosinate insensitivity but no whole‐plant resistance, showing trade‐offs between catalytic function and herbicide binding and providing a baseline for future studies on target‐site glufosinate resistance.

Enhancement of glyphosate efficacy on Amaranthus palmeri by exogenous quinate application

Pesticide Biochemistry and Physiology, 2019
Glyphosate is a widely used herbicide targeting the enzyme 5-enolpyruvylshikimate 3-phosphate synthase (EPSPS) in the aromatic amino acid biosynthesis pathway (shikimate pathway) and provoking accumulation of quinate, a secondary metabolite synthesized through a side branch of this pathway.

Male‐specific Y‐chromosomal regions in waterhemp (Amaranthus tuberculatus) and Palmer amaranth (Amaranthus palmeri)

New Phytologist, 2020
Summary Amaranthus tuberculatus and Amaranthus palmeri are agronomically important weed species, both with stable dioecious reproductive systems. An understanding of the genetic basis of sex determination may lead to new methods of managing these troublesome weeds.

Characterization of the Amaranthus palmeri Physiological Response to Glyphosate in Susceptible and Resistant Populations [PDF]

Journal of Agricultural and Food Chemistry, 2015
The herbicide glyphosate inhibits the plant enzyme 5-enolpyruvylshikimate3-phosphate synthase (EPSPS) in the aromatic amino acid (AAA) biosynthetic pathway. The physiologies of an Amaranthus palmeri population exhibiting resistance to glyphosate by EPSPS gene amplification (NC-R) and a susceptible population (NC-S) were compared.
