The present invention pertains to nucleic acid molecules isolated from
Arabidopisis thaliana comprising nucleotide sequences that encode
proteins for biotic and abiotic stress tolerance. The invention
particularly relates to methods of using nucleic acid molecules and/or
proteins from Arabidopisis in transgenic plants to confer enhanced biotic
and/or abiotic stress tolerance, and to use such nucleic acids to assist
germplasm enhancement by breeding. In particular, the invention pertains
to nucleic acid molecules isolated from Arabidopisis thaliana of the BOS1
cDNA and genomic gene and encoding the BOS1 polypeptide. The present
invention also pertains to nucleic acid molecules isolated from
Arabidopisis thaliana that encode a promoter from the BOS1 gene, and
methods of using the promoter. Also, the invention relates to host cells,
plants or progeny thereof comprising the nucleic acid molecules or
recombinant molecules described herein.
