Abstract

We have previously shown by cDNA cloning that a higher plant, Arabidopsis thaliana, possesses at least two CDC2 genes (CDC2a and CDC2b) similar to the cell-cycle-controlling cdc2 gene of Schizosaccharomyces pombe. To understand the exon-intron organization of these genes, genomic clones were isolated and their nucleotide sequences determined. The coding and 5′-untranslated regions of CDC2a were interrupted by seven and one introns, respectively, whilst CDC2b contained three introns within the coding portion. These intron positions partly overlapped with each other and with those of the yeast cdc2 gene, nevertheless the lengths and sequences of the corresponding introns were diverse.
