We report the characterization of a 1388 bp genomic fragment from Arabidopsis thaliana that encompasses the entire transcription unit of the gene encoding the precursor of 10 kDa polypeptide of photosystem II, 495 bp of the 5' flanking region and 73 bp of the 3' boundary of the gene. The deduced protein shows 78% and 73% homology, respectively, with its homologues from potato and spinach. The transcription of the gene seems to be greatly enhanced by light and only transcribed in substantial amounts in leaves and stems. Analysis of the putative 5' regulatory region of the gene shows homology with several cis-elements involved in light regulation of the transcription.
