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 ...

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.

Herbicide sensitivity of transgenic multiple herbicide‐tolerant oilseed rape

Pest Management Science, 2002
AbstractGlyphosate and glufosinate‐ammonium herbicide tolerance traits were combined into both winter and spring lines of Brassica napus L. This allowed the study of possible interactions between these transgenes in two genetic backgrounds when treated with a variety of herbicides.

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

Why are there not more herbicide-tolerant crops?

Pest Management Science, 2005
AbstractHerbicide‐tolerant (HT) varieties of corn, soybean, canola (oilseed rape) and cotton have been grown since the mid‐1990s, and have been widely adopted by farmers in several countries. HT genes have been inserted into or selected for in many other species, including almost all major crop species in the world and many minor crops and ornamental ...
