Abstract: Methods and compositions to adapt corn to grow in a geographical location such as northern dry climatic region are disclosed. By modulating phenotypic parameters such as for example flowering time, plant architecture, abiotic stress tolerance in a modular approach, corn is modified to grow in a geographical location that generally does not support growth corn to generate higher yields. Various methods, genes, and compositions are disclosed to improve adaptability and productivity of corn in the desired climatic conditions.

Abstract: The present invention provides a method, apparatus, and system for efficient, high throughput, consistent cleaning of soil from the root system of a plant. In one embodiment, the method generally comprises positioning a plant adjacent a sprayer assembly having at least one nozzle angled so as to impact the root system at a predetermined position, providing a stream of water from a reservoir through the nozzle of the sprayer assembly, and rotating at least one of the root system and the nozzle relative to the other to remove the soil from the root system. The present invention further describes a recycling system adapted to recycle water expended during the cleaning process to minimize losses and to capture and return dislodged soil to the field from which the plant is extracted.

Abstract: 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.
