Analysis of the Accase Mutation Profile of Italian Ryegrass (Lolium Perenne SSP. Multiflorum) Accessions Resistant to Accase Inhibitors
Lolium perenne ssp. multiflontm (Italian ryegrass) resistant to ACCase inhibiting herbicides has been reported in many wheat producing counties across Arkansas. Resistance is believed to be the result of point mutations creating amino acid substitutions in the CT domain of the plastidic ACCase gene. This study explores the occurrence of mutations in the A CCase gene of ryegrass populations. Pla...
متن کاملEPSPS variability, gene expression, and enzymatic activity in glyphosate-resistant biotypes of Digitaria insularis.
Weed resistance to herbicides is a natural phenomenon that exerts selection on individuals in a population. In Brazil, glyphosate resistance was recently detected in Digitaria insularis. The objective of this study was to elucidate mechanisms of weed resistance in this plant, including genetic variability, allelism, amino acid substitutions, gene expression, and enzymatic activity levels. Most ...
متن کاملDifferential content of glyphosate and its metabolites in Digitaria insularis biotypes
Experiments were carried out in controlled conditions to analyze the role of metabolism of glyphosate in Digitaria insularis (sourgrass) biotypes with differential response to the herbicide.
متن کاملMutations in the plastidic ACCase gene endowing resistance to ACCase-inhibiting herbicide in Phalaris minor populations from India
Littleseed canarygrass (Phalaris minor Retz.) is one of the most common and troublesome weeds infesting wheat crop in India. Repeated use during the last two decades of the ACCase-inhibiting herbicide (clodinafop) to control this weed has resulted in the occurrence of resistance. Fifty-three P. minor populations were collected from wheat fields in Haryana and Punjab states of India. The dose-re...
متن کاملCross-resistance to different aromatase inhibitors in breast cancer treatment.
Recent studies have documented the biochemical and clinical efficacy of novel aromatase inhibitors. These drugs belong to one of two classes: non-steroidal and steroidal drugs, known to be different with respect to enzyme binding site and their effect on the aromatase enzyme. Several studies have now confirmed a lack of complete cross-resistance to drugs of the two classes. While some of these ...
