摘要:
Linoleic acid is converted into γ-linolenic acid by the enzyme Δ6-desaturase. The present invention is directed to isolated nucleic acids comprising the Δ6-desaturase gene. More particularly, the isolated nucleic acid comprises the promoter, coding region and termination regions of the Δ6-desaturase gene. The present invention provides recombinant constructions comprising the Δ6-desaturase coding region in functional combination with heterologous regulatory sequences. The nucleic acids and recombinant constructions of the instant invention are useful in the production of GLA in transgenic organisms.
摘要:
The present invention is directed to 5' regulatory regions of two Arabidopsis seed-specific genes, AtS1 and AtS3. The 5' regulatory regions, or parts thereof, when operably linked to either the coding sequence of a heterologous gene or a sequence complementary to a native plant gene, direct expression of the coding sequence or complementary sequence in a plant seed. The regulatory regions are useful in expression cassettes and expression vectors for the transformation of plants. Also provided are methods of modulating the levels of a heterologous gene such as a fatty acid synthesis or lipid metabolism gene by transforming a plant with the subject expression cassettes and expression vectors.
摘要:
Agrochemical combinations including an effective amount of an insecticide which includes an insecticide from the chloronicotinyl family A such as imidacloprid, acetamiprid or nitenpyram, and an insecticide B having a pyrazole, pyrrole or phenylimidazole group; compositions containing one or both of said two active substances; and a method for treating and protecting plants, and seeds in particular, from insects or arthropods, by applying a combination of both active substances, are disclosed. A composition containing both active substances may also be applied. Alternatively, two compositions each containing one of the active substances may be applied simultaneously or sequentially to ensure a combined effect.

摘要:
Fungicidal combination comprising a compound A which is iprodione, vinclozoline or procymidone, and a compound B which is cyprodinil, also known as 2-phenylamino-4-cyclopropyl-6-methylpyrimidine, fungicidal compositions comprising same, and method of preventing fungal attacks on crops.
摘要:
Herbicidal compositions, characterized in that they comprise: (a) as active ingredient, a herbicidally effective amount of a mixture comprising HERB1, known under the chemical name of 1-methyl-3-�2-fluoro-4-chloro-5-(ethoxycarbonylmethoxy)phenyl!-4-chloro-5-difluoromethoxypyrazole (I), and a second herbicide (II) selected from the group consisting of diflufenican, bromoxynil, flurtamone, aclonifen and isoproturon; and (b) an agriculturally acceptable carrier therefor. ##STR1##
摘要:
A herbicidal composition containing as active ingredients the following two components, (A): at least one of 1,3-oxazin-4-one derivatives represented by the following general formula (I) ##STR1## wherein, R is a methyl or an ethyl group, Y is a halogen atom, a lower haloalkyl or a lower haloalkoxy group, and n is 0, 1, 2 or 3, and (B): at least one compound selected from certain known herbicides. It is possible, by use of this composition, to completely control annual gramineous weeds, annual broad-leaved weeds and perennial weeds, without causing any phytotoxicity on agriculturally important crops at a low dose of the active ingredients.
摘要:
