  • Publication number: 20120240290
    Abstract: The present invention provides compositions and methods for modulating flowering time in plants. Maize RAP2.7 nucleotide sequences are disclosed which upon overexpression cause later flowering and when inhibited cause earlier flowering. Also disclosed is a DNA sequence which acts as a regulator/enhancer of RAP2.7, termed VGT1. This sequence does not code for any known protein, but acts as either a RNAi element or a regulatory DNA or RNA element that either directly regulates expression of flowering genes such as Rap2.7 or specifically targets expression of other genes which control flowering genes such as Rap2.7. This element this can be used as a sequence—based marker to identify inbred and hybrids which have altered maturity. Methods for expressing these nucleotide sequences in a plant for modifying maturity and flowering in plants are provided as well as expression constructs, vectors, transformed cells and plants.

  • Publication number: 20110185444
    Abstract: This invention relates generally to the detection of genetic differences among soybeans. More particularly, soybean quantitative trait loci (QTL) associated with herbicide tolerance, including tolerance to one or more of an HPPD-inhibitor herbicide, such as mesotrione and isoxazole herbicides, and/or a PPO inhibitor herbicide; soybean plants possessing these QTLs; and genetic markers that are indicative of phenotypes associated with such herbicide tolerance are provided. Methods and compositions for use of these markers in genotyping of soybean and selection are also disclosed, as are methods and compositions for use of herbicides for weed control. Also disclosed are isolated polynucleotides and polypeptides relating to such tolerance or sensitivity and methods of introgressing such tolerance into a plant by breeding or transgenically, or by a combination thereof.

  • Patent number: 7838263
    Abstract: This invention relates to polynucleotide sequences encoding a gene that can confer resistance to at least one herbicide. It further relates to plants and seeds of plants carrying chimeric genes comprising said polynucleotide sequences, which enhance or confer resistance to at least one herbicide, and methods of making said plants and seeds. The invention further presents sequences that can be used as molecular markers that in turn can be used to identify the region of interest in corn lines resulting from new crosses and to quickly and efficiently select the best lines for breeding strategies by avoiding sensitive lines. Methods of identifying a plant with an Nsf1 locus using molecular markers are described.
