The present invention is directed to promoter sequences and promoter control elements, polynucleotide constructs comprising the promoters and control elements, and methods of identifying the promoters, control elements, or fragments thereof. The invention further relates to the use of the present promoters or promoter control elements to modulate transcript levels in plants, and plants containing such promoters or promoter control elements.

Disclosed herein are method of altering CAM pathways in plants. In some examples, a disclosed method includes overexpressing one or more genes encoding one or more enzymes that carry out the basic biochemical sequence of nocturnal CO.sub.2 fixation (carboxylation) into C.sub.4 acids (malate), store C.sub.4 acids in the vacuole of the plant, and/or then decarboxylate and refix the released CO.sub.2 by C.sub.3 photosynthesis during the subsequent day in a plant cell, thereby altering CAM in the plant cell. Also disclosed herein are isolated polynucleotide sequences, transformation vectors, transgenic plant cells, plant part, and plants. The disclosed methods and compositions can be used to improve the water-use efficiency and drought tolerance and durability of plants, such as in plants in arid environments, and also enhance the ability of plants to perform.

The present invention provides novel DNA molecules and constructs, including their nucleotide sequences, useful for modulating gene expression in plants and plant cells. The invention also provides transgenic plants, plant cells, plant parts, seeds, and commodity products comprising the DNA molecules operably linked to heterologous transcribable polynucleotides, along with methods of their use.

This present invention relates to isolation and derivation of nucleic acid sequences from monocot plants, preferably rice that are capable of driving and/or regulating a stress induced expression of an operably linked nucleic acid. The present invention also is directed to the use of the isolated nucleic acid to drive and/or regulate a stress-induced expression of an operably linked nucleic acid. The isolated nucleic acid sequence of the present invention as set forth in SEQ ID NO 3 or SEQ ID NO 6 or SEQ ID NO 7 or SEQ ID NO 9 or the complement thereof can be an inducible promoter. The promoters of the invention can be induced by abiotic stress such as water, cold, heat and/or salinity or a biotic stress such as by a virus, bacteria, or fungi.

The present invention relates to a genetically engineered plant in which the G-box motif has been inactivated, thereby inhibiting the thermosensory response, and methods for preparing such a plant.

Embodiments of the present invention provide for a transgenic plan, methods of making and DNA constructs for use in the transgenic plant which transgenic plant is capable of modulating its photosynthetic antenna complex composition in response to increases or decreases in light intensity by modulation of the ratio of chlorophyll a to chlorophyll b such that there is an increase in the Chl a/b ratio at high light intensity and a decrease in the Chl a/b ratio at low light intensity versus wild-type plants grown in the same conditions.
