Abstract: When used in admixture with fludioxonil, metalaxyl having a high R-enantiomer content of more than 70% by weight, or pure R-metalaxyl, exhibits a markedly enhanced fungicidal action against plant diseases. At the same time, the high R-enantiomer content accelerates the degradability of metalaxyl in the soil.

Abstract: We have cloned and expressed the cDNA for human liver mevalonate pyrophosphate decarboxylase, an enzyme of the cholesterol synthesis pathway. This cDNA encodes a 400 amino acid protein (43 kDa) which resembles the coding sequence of an unidentified and incomplete open reading frame adjacent to the COQ2 gene of Saccharomyces cerevisiae. We also found an expression sequence tag clone made from human infant brain cDNA to be almost identical to our cDNA sequence.

Abstract: The present invention provides a dual method for producing male-sterile plants. Two genetically transformed plants, parents 1 and 2 are crossed to obtain male-sterile offspring. Parent 1 is transformed with an expression cassette comprising a nucleotide sequence encoding an anther-specific promoter which is operably linked to a nucleotide sequence encoding a transactivator. Parent 2 is transformed with an expression cassette comprising a target nucleotide sequence, which is capable of being activated by the transactivator, operably linked to a nucleotide sequence which encodes RNA or a polypeptide which will disrupt the formation of viable pollen. Therefore, crossing parent 1 with parent 2 results in male-sterile offspring. The male-sterile plants are useful for producing hybrid seed.The invention also provides compositions and methods for high level expression of a coding region of interest in a plant.

Abstract: Methods are provided for selecting parental plants having disease resistance and for using these plants in breeding programs. In one method of the invention, lesion mimic mutants are screened for either resistance to a pathogen of interest or for the expression of systemic acquired resistance (SAR) genes. Such mutants having the desired traits or expressing the desired genes are then used in breeding programs. Parent plants can also be selected based on the constitutive expression of SAR genes. These mutants are phenotypically normal yet exhibit a significant level of disease resistance. Also disclosed are plant mutants that do not express systemic acquired resistance genes even when induced by a pathogen and methods of use for such mutants.
