Identifying Chloris Species from Cuban Citrus Orchards and Determining Their Glyphosate-Resistance Status
The Chloris genus is a C4 photosynthetic species mainly distributed in tropical and subtropical regions. Populations of three Chloris species occurring in citrus orchards from central Cuba, under long history glyphosate-based weed management, were studied for glyphosate-resistant status by characterizing their herbicide resistance/tolerance mechanisms. Morphological and molecular analyses allow...
متن کاملCharacterization of glyphosate resistance in cloned Amaranthus palmeri plants
Glyphosate-resistant Palmer amaranth from Georgia (GA), USA, possesses multiple copies of the gene that encodes 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), the enzyme target site of this herbicide. The cloned plants of glyphosate-resistant and glyphosatesusceptible Palmer amaranth biotypes from Mississippi (MS), USA, and GA were evaluated for glyphosate injury (digital imaging) in leaf...
متن کاملGene amplification confers glyphosate resistance in Amaranthus palmeri.
The herbicide glyphosate became widely used in the United States and other parts of the world after the commercialization of glyphosate-resistant crops. These crops have constitutive overexpression of a glyphosate-insensitive form of the herbicide target site gene, 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). Increased use of glyphosate over multiple years imposes selective genetic pres...
متن کاملInterspecific hybridization transfers a previously unknown glyphosate resistance mechanism in Amaranthus species
A previously unknown glyphosate resistance mechanism, amplification of the 5-enolpyruvyl shikimate-3-phosphate synthase gene, was recently reported in Amaranthus palmeri. This evolved mechanism could introgress to other weedy Amaranthus species through interspecific hybridization, representing an avenue for acquisition of a novel adaptive trait. The objective of this study was to evaluate the p...
متن کاملWeed Management in Citrus Orchards in Khuzestan Using Summer Cover Crop Mulch
Objective: Importance of management of gardens weeds is an issue that unfortunately has less been investigated by weeds researchers of country. One of the most important restrictive agents of cultivated surface and producing crops of Citrus orchards are weeds. Methods: To achieve this purpose, a research was performed in plot of Valencia orange trees of citrus fruits of Dezful in 2013. This pro...
