Abstract: The present invention relates to nucleic acid sequences from the dicotyldonus plant Arabidopsis thaliana and, in particular, to genomic DNA sequences. The invention encompasses nucleic acid molecules present in non-coding regions as well as nucleic acid molecules that encode proteins and fragments of proteins. In addition, proteins and fragments of proteins so encoded and antibodies capable of binding the proteins are encompassed by the present invention. The invention also encompasses oligonucleotides including primers, e.g. useful for amplifying nucleic acid molecules, and collections of nucleic acid molecules and oligonucleotides, e.g. in microarrays. The invention also provides constructs and transgenic cells and organisms comprising nucleic acid molecules of the invention.
