- Plants Tolerant to HPPD Inhibitor Herbicides
-
The present invention relates to nucleic acid sequences encoding a hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27, abbreviated herein as HPPD) obtained from protists belonging to the family Blepharismidae, as well as the proteins encoded thereby, and to a chimeric gene which comprises such nucleic acid sequence, and to the use of such nucleic acid sequences, proteins or chimeric genes for obtaining plants which are tolerant to HPPD inhibitor herbicides.

- Synthesis of O,O-diethyl arylthiophosphonate from O-aryl-O,O- diethylthiophosphate
-
The synthesis of O,O-diethyl 2-hydroxyarylthiophosphonate is reported by using a [1,3]-rearrangement. This method is achieved in high yield from ortho-bromophenols derivatives by a two-step process. Georg Thieme Verlag Stuttgart.

- Active substances for increasing the stress defense in plants to abiotic stress, and methods of finding them
-
The invention relates to a method of finding compounds which increase the tolerance of plants to abiotic stress factors acting on this plant, such as, for example, temperature (such as chill, frost or heat), water (such as dryness, drought or anoxia), or the chemical load (such as lack of or excess of mineral salts, heavy metals, gaseous noxious substances) by increasing the expression of plant-endogenous proteins, and to the use of these compounds for increasing the tolerance in plants to abiotic stress factors.

- Carbofuran compositions for problem soils
-
The insecticide carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate) is combined with an organophosphorus additive of the formula STR1 in which R1 is C1 -C4 alkyl, R2 is C1 -C4 alkyl, R3 is C1 -C4 alkylene, X is oxygen or sulfur, and n is zero or one, for application to soil where previous applications of carbofuran have resulted in successive decreases in the insecticidal activity of carbofuran. The lost activity of the carbofuran is thereby restored.
