Publication number: 20120240290Abstract: 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.Type: ApplicationFiled: March 27, 2012Publication date: September 20, 2012Applicant: PIONEER HI BRED INTERNATIONAL INCInventors: Dwight Tomes, Silvio Salvi, Michele Morgante, Giorgio Sponza, Edward Bruggemann, Xiaomu Niu, Bailin Li, Roberto Tuberosa

Publication number: 20120071348Abstract: The present invention provides for rapid and large scale evaluation of expression of, or function of, nucleotide sequences in plants. The invention comprises three specific components which provide for fast and large scale evaluation of nucleotide sequences. The first component includes delivery in either a single event a library of different engineered vectors or a single engineered vector for a single target nucleotide sequence comprising sequences the function of which is desired to be known in plant cells. Surprisingly, applicants have discovered that, the introduction of multiple vectors to plant cells predominantly results in individual transgenic plants which contain only a single transformation event. The second feature of the invention involves a highly transformable, fast cycling and/or miniature size plant and the final step involves mass scale analysis of T0 plants for various phenotypes and plasmid rescue to identify the nucleotide sequence present in a particular phenotype.Type: ApplicationFiled: March 28, 2011Publication date: March 22, 2012Applicant: PIONEER HI BRED INTERNATIONAL INCInventors: MARC C.
