Engineering Herbicide Tolerance in Transgenic Plants

Science, 1986
The herbicide glyphosate is a potent inhibitor of the enzyme 5-enolpyruvylshikimate-3-phosphate (EPSP) synthase in higher plants. A complementary DNA (cDNA) clone encoding EPSP synthase was isolated from a complementary DNA library of a glyphosate-tolerant Petunia hybrida cell line (MP4-G) that overproduces the ...

Cytochromes P450 for engineering herbicide tolerance

Trends in Plant Science, 2000
In recent years, genome sequencing has revealed that cytochromes P450 (P450s) constitute the largest family of enzymatic proteins in higher plants. P450s are mono-oxygenases that insert one atom of oxygen into inert hydrophobic molecules to make them more reactive and hydrosoluble.

Sporophytic-gametophytic herbicide tolerance in sugarbeet

Theoretical and Applied Genetics, 1985
In vitro selection procedures for herbicide tolerance were initially developed in the sporophytic generation of sugarbeet (Beta vulgaris L.), and then tested in the gametophytic generation. The primary objective of our study was to develop and evaluate in vitro techniques for identifying genotypes within heterogeneous seedling populations tolerant to ...

Herbicidal inhibitors of amino acid biosynthesis and herbicide-tolerant crops

Amino Acids, 2006
Acetohydroxyacid synthase (AHAS) inhibitors interfere with branched-chain amino acid biosynthesis by inhibiting AHAS. Glyphosate affects aromatic amino acid biosynthesis by inhibiting 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). Glufosinate inhibits glutamine synthetase and blocks biosynthesis of glutamine.

Technology Transfer for Herbicide-Tolerant Weeds and Herbicide-Tolerant Crops

Weed Technology, 1992
Weed resistance has not generally been considered a serious problem where herbicide rotations and combinations are used. Herbicide-tolerant crops present new opportunities for decreasing risk of crop injury, decreasing carryover problems, broadening control spectrum, and for using herbicides that present less risk to the environment. However, herbicide-

Herbicide-tolerant mutants of corn

Genome, 1989
Eight imidazolinone herbicide resistant corn cell lines were obtained from in vitro cell culture selections. Plants were regenerated from five of the lines and resistant progeny obtained from four. Of the four, one line showed cross resistance to a sulfonylurea herbicide (class A), while three lines were resistant only to imidazolinones (class B). The

Engineering herbicide tolerance into crops

Trends in Biotechnology, 1990
Abstract Herbicide treatments of crops allow economic weed control and provide cost-effective increases in agricultural productivity. Although herbicides currently in use combine a high degree of effectiveness with favourable production costs, non-toxicity and rapid biodegradation, they often lack selectivity, thus limiting their use to pre-emergence ...

Guar Tolerance to Postemergence Herbicides

Weed Technology, 2007
Guar production in the United States is limited to a relatively small region in the semiarid southern Great Plains of Texas and Oklahoma. The lack of POST broadleaf herbicides is a potential limiting factor to increased production. A greenhouse study was initiated in 2001 at the Texas A&M Research Center near Vernon, TX to evaluate guar tolerance to 10

Herbicide Tolerant Forest Trees

2000
At the vanguard of biotechnological applications to agriculture are the transgenic annual field crops, and already in the USA alone, there are millions of hectares of transgenic cotton, corn, soybean and canola whose produce is being traded in commerce and the areas are increasing almost exponentially.

Genetically Modified Herbicide-Tolerant Crops, Weeds, and Herbicides: Overview and Impact

Environmental Management, 2015
Genetically modified (GM) crops have been and continue to be a subject of controversy despite their rapid adoption by farmers where approved. For the last two decades, an important matter of debate has been their impact on pesticide use, particularly for herbicide-tolerant (HT) crops. Some claim that these crops bring about a decrease in herbicide use,
