Abstract: The present invention relates to azirine containing compounds useful as anti-angiogenesis agents and preparation thereof. Particularly the present invention relates to azirine containing compounds of formula I, Formula I wherein R1, R2 and R3 are same as defined in the description. The compounds of the present invention are with asymmetric centers this, they are mixture of enantiomers and mixture of diastereomers in some cases. The present invention includes the individual enantiomers and diastereomeric forms of the compound formula I besides the mixtures thereof.

Abstract: The present invention relates to DYAD genes, mutants thereof, and use of them for making plants that retain heterozygosity of the female parent plant. The invention also encompasses plants, plant tissues, and seeds of plants that have a dyad phenotype and so retain heterozygosity of the female parent, either constitutively or conditionally. The invention is useful for propagating desired hybrid phenotypes in a manner of an apomictic plant and for increasing the ploidy of a plant genotype, which may result in plants having increased biomass.

Abstract: Expression of DNA sequences in a preferred manner in the roots of a plant is often desirable. For instance improved resistance to soil-borne pathogens may be attained by expression of a pathogen resistance gene in a part of the plant such as the root that may be the site of infection. It is therefore desirable to develop tissue-preferred promoters that are capable of directing the expression in a preferred manner in plant roots, of another DNA sequence that is operably linked to the promoter sequence. Further, it is desirable to have access to multiple promoters with similar expression patterns since these may differ with respect to their degree of successful applicability in different plant species where such expression may be desired. Here we describe the isolation and analysis of a DNA sequence from the upstream regulatory region of the At1g73160 gene of Arabidopsis.
