Abstract: Clusters of plant genes that are regulated in response to one or more stress conditions are provided, as are isolated plant stress-regulated genes, including portions thereof comprising a coding sequence or a regulatory element, and to consensus sequences comprising a plant stress-regulated regulatory element. In addition, a recombinant polynucleotide, which includes a plant stress-regulated gene, or functional portion thereof, operatively linked to a heterologous nucleotide sequence, is provided, as are transgenic plants, which contain a plant stress-regulated gene or functional portion thereof that was introduced into a progenitor cell of the plant. Also provided are methods of using a plant stress-regulated gene to confer upon a plant a selective advantage to a stress condition, methods of identifying an agent that modulates the activity of a plant stress-regulated regulatory element, and methods of determining whether a plant has been exposed to a stress.

Abstract: Abiotic stress responsive polynucleotides and polypeptides are disclosed. Also disclosed are vectors, expression cassettes, host cells, and plants containing such polynucleotides. Also provided are methods for using such polynucleotides and polypeptides, for example, to alter the responsiveness of a plant to abiotic stress.

Abstract: Polynucleotides encoding transcription factors of cereals and in particular rice are provided. Also provided are re-combinant vectors, expression cassettes, host cells and plants containing the polynucleotides. Methods for using the polynucleotides to alter resistance or tolerance of plants to stress, alter biological pathways, and alter gene expression are also provided.

Abstract: The invention discloses a set of genes the expression products of which are up-regulated during the grain filling process in rice and active in different metabolic pathways involved in nutrient partitioning. The invention also discloses the use of said genes to modify the compositional and nutritional characteristics of the plant grain.

Abstract: The present subject matter provides a method for enhancing the abiotic stress tolerance of a plant. Polynucleotides isolated from rice (Oryza sativa) and encoding polypeptides for abiotic stress tolerance are also described.

Abstract: The invention relates to proteins that are involved in the transport and translocation of phosphorous in plants and to nucleic acid molecules encoding those proteins. The invention further provides the means and tools for modifying the uptake and translocation of phosphorous in photosynthetic organisms such as plants.

Abstract: An isolated polynucleotide encoding a monocot cap binding protein 80 (CBP80) is provided. Further provided are methods of using an inhibitor of monocot CBP80 to increase the drought tolerance of plants.

Abstract: The invention provides a method to identify a plurality of plant promoters having a particular characteristic as well as the sequence of promoters having one of those characteristics.
