ABSTRACT
From a genomic library of Brassica campestris (brown sarson cv. B54), we have cloned and sequenced about 2 kb of upstream regulatory region from one of the 2S albumin-coding gene family. The sequence has several seed-specific promoter motifs. A sequence alignment of the 5' flanking regions of the available Brassica 2S storage protein genes showed that our sequence is a double crossover recombinant product of the two members of the napin gene family. A possible explanation of this fact is that Brassica species evolved through gene duplication and recombination from a common ancestor with fewer number of chromosomes and genes.
