Late-season surveys to document seed rain potential of Palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus) in Texas cotton. [PDF]
PLoS ONE, 2020 Weed escapes are often present in large production fields prior to harvest, contributing to seed rain and species persistence. Late-season surveys were conducted in cotton (Gossypium hirsutum L.) fields in Texas in 2016 and 2017 to identify common weed ...

Male Linked Genomic Region Determines Sex in Dioecious Amaranthus palmeri. [PDF]
J Hered, 2020 Dioecy, the separation of reproductive organs on different individuals, has evolved repeatedly in different plant families. Several evolutionary paths to dioecy have been suggested, but the mechanisms behind sex determination is not well understood.

Responses of Fungal Assembly and Co-Occurrence Network of Rhizosphere Soil to Amaranthus palmeri Invasion in Northern China [PDF]
Journal of Fungi, 2023 The interaction between invasive plants and soil microbial communities is critical for plant establishment. However, little is known about the assembly and co-occurrence patterns of fungal communities in the rhizosphere soil of Amaranthus palmeri.

PPO2 Mutations in Amaranthus palmeri: Implications on Cross-Resistance [PDF]
Agriculture (Switzerland), 2021 In Arkansas, resistance to protoporphyrinogen IX oxidase (PPO)-inhibiting herbicides in Amaranthus palmeri S. Wats. is mainly due to target site mutations. Although A. palmeri PPO-mutations are well investigated, the cross-resistance that each ppo mutant endows to weed populations is not yet well understood.

Inheritance of 2,4-dichlorophenoxyacetic acid (2,4-D) resistance in Amaranthus palmeri. [PDF]
Sci Rep, 2022 AbstractIn this study, the inheritance of 2,4-D resistance in a multiple herbicide-resistant Palmer amaranth (KCTR) was investigated. Direct and reciprocal crosses were performed using 2,4-D-resistant KCTR and susceptible KSS plants to generate F1 progenies.

Amaranthus palmeri, a second record for Africa and notes on A. sonoriensis nom. nov.
Bothalia: African Biodiversity & Conservation, 2017 Background: Amaranthus is a critical genus from a taxonomic point of view because of its high phenotypic variability, which has led to nomenclatural disorder, misapplication of names, and erroneous species identification.
