摘要:
Linoleic acid is converted into .gamma.-linolenic acid by the enzyme .DELTA.6-desaturase. The present invention is directed to isolated nucleic acids comprising the .DELTA.6-desaturase gene. More particularly, the isolated nucleic acid comprises the promoter, coding region and termination regions of the .DELTA.6-desaturase gene. The present invention provides recombinant constructions comprising the .DELTA.6-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:
A termite control composition for soil treatment containing a 3-cyano-1-(substituted phenyl)pyrazole and a pyrethroid compound as effective ingredients, and a method of controlling pests such as termites using said composition. The termite control composition is improved for soil treatment as well as for the ability to prevent termites from passing through a pesticidally treated layer.

摘要:
Plant cells are transformed by: (i) transforming a plant cell whose growth is sensitive to inhibition by a sulfonamide or a salt thereof with a chimaeric gene comprising (a) a plant promoter, (b) a sulfonamide resistance gene having a sequence encoding a transit peptide fused to the 5'-end of the resistance gene and (c) a plant polyadenylation/terminator sequence; (ii) selecting a transformed plant cell whose growth is resistant to inhibition by a sulfonamide or salt thereof; (iii) optionally, regenerating from the transformed plant cell a genetically transformed plant which exhibit the said resistance; (iv) optionally, obtaining seed from the regenerated plant; and (v) optionally, propagating plants from the seed. The growth of weeds can be controlled at a locus where a transgenic plant obtained as above is being cultivated by applying to the locus an effective amount of a herbicide, such as asulam, which acts by inhibiting dihydropteroate synthase. The sulfonamide resistance gene can be also used as a selectable marker. The sequence of a sulfonamide resistance gene is presented.

摘要:
Chimeric gene for conferring to plants an increased tolerance to a herbicide having as its target EPSPS comprises, in the direction of transcription, a promoter region, a transit peptide region, a coding sequence for glyphosate tolerance and a polyandenylation signal region, wherein the transit peptide region comprises, in the direction of translation, at least one transit peptide of a plant gene encoding a plastid-localized enzyme and then a second transit peptide of a plant gene encoding a plastid-localized enzyme. Production of glyphosate-tolerant plants is disclosed.
