Analysis of the agronomic interest characteristics for the management of Conyza blakei, Conyza bonariensis, Conyza sumatrensis, and Conyza lorentzii

Agrociencia, 2020
Conyza genus includes herbs of ruderal habit, also referred to weeds in pastures, perennial crops, and no tillage crops. The insuitable use of herbicides, the incorrect identification of species, and the lack of monitoring, among others, explain the fact

Thirty years of glyphosate-resistant crops and weeds: Current situation and future prospects. [PDF]

Pest Manag Sci
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

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

Plant Genome
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 ...

Transcription of putative tonoplast transporters in response to glyphosate and paraquat stress in Conyza bonariensis and Conyza canadensis and selection of reference genes for qRT-PCR. [PDF]

PLoS ONE, 2017
Herbicide resistance is a challenge for modern agriculture further complicated by cases of resistance to multiple herbicides. Conyza bonariensis and Conyza canadensis are invasive weeds of field crops, orchards, and non-cropped areas in many parts of the

Biologia e ecofisiologia de buva (Conyza bonariensis e Conyza canadensis) [PDF]

Ciencia Rural, 2008
Conyza bonariensis (L.) Cronquist e Conyza canadensis (L.) Cronquist são duas espécies de plantas daninhas pertencentes à família Asteraceae. Com freqüência, elas infestam pomares, vinhedos e outras culturas, como milho, soja e algodão e, também, culturas forrageiras, pastagens e áreas não-cultivadas.

Comparative Phytochemical Profiles of Medicinal Plants Used for Wound Treatment: Insights From Wild and Hydroponically Cultivated Species in Lugazi Diocese, Uganda. [PDF]

Chem Biodivers
ABSTRACT Medicinal plants such as Centella asiatica, Conyza sumatrensis, and Justicia betonica are widely used in Uganda for traditional wound healing. However, the impact of cultivation conditions on their therapeutic potential remains poorly understood.

Toxicity of aqueous extracts of Ilex paraguariensis A.St.-Hil. about Euphorbia heterophylla L. [PDF]

Pest Manag Sci
Aqueous extracts of Ilex paraguariensis A.St.‐Hil. strongly inhibit Euphorbia heterophylla L. germination and early seedling growth, but show mild phytotoxicity on mature plants, paradoxically promoting biomass via antioxidants. Abstract BACKGROUND The escalating challenge of herbicide‐resistant weeds, exemplified by Euphorbia heterophylla L.

The population genomics of Conyza spp. in soybean macroregions suggest the spread of herbicide resistance through intraspecific and interspecific gene flow [PDF]

Scientific Reports
Herbicide-resistant Conyza spp. are a threat to many crops. These widespread weeds are closely related species and often cooccur. To characterize the origins of their resistance and the mechanisms underlying their spread, we assessed the genomic ...

RNAi technology development for weed control: all smoke and no fire? [PDF]

Pest Manag Sci
Despite the potential of Spray‐Induced Gene Silencing in weed management several critical points such as molecular target, weed species of interest as well as delivery techniques need to be addressed. Abstract RNA interference (RNAi) technology, specifically Spray‐Induced Gene Silencing (SIGS), holds potential as an innovative approach for selective ...
