Herbicide tolerant regenerates of potato

Theoretical and Applied Genetics, 1987
Culture-derived plants and cell cultures of potato (Solanum tuberosum L.) respond to the application of the herbicides SYS 67 ME (MCPA) and OMNIDEL (Na-2,2-dichloropropionate) in a comparable fashion. By gradually increasing the herbicide concentration, cell lines were developed which tolerated 50 mg/l of ME or 300 mg/l of OMNIDEL. Any further increase

Herbicide Tolerance of Buffalograss

Applied Turfgrass Science, 2006
Buffalograss (Buchloe dactyloides (Nutt.) Engelm.) is a low‐maintenance turfgrass alternative in many parts of the United States. When buffalograss is seeded, competition from weeds can significantly delay establishment. Additional research is needed on buffalograss seedling tolerance to herbicides, including newer herbicides such as the sulfonylurea ...

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 Drift from Genetically Engineered Herbicide-Tolerant Crops

Environmental Science & Technology, 2021
In recent years, off-target herbicide drift has been increasingly reported to lead to damage to nontarget vegetation in the U.S. These reports have coincided with the widespread adoption of genetically modified crops with new herbicide-tolerance traits.

Herbicide Phytotoxicity Model for Assessing Herbicide Tolerance

Journal of Agronomy and Crop Science, 1988
AbstractA herbicide phytotoxicity model was used to investigate differences in herbicide tolerance between two species of Amsinckia (A. intermedia Fischer and Meyer and A. gloriosa Suksdorf) to the herbicide bromoxynil (3,5‐dibromo‐4‐hydroxybenzonitrile).

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 ...

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.

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.
