Title Cloning and sequencing of an apparently recombinant promoter for napin gene from Brassica campestris genomic library and its evolutionary significance
 
Creator Bhattacharyya, Somnath

Description 221-226
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 o f 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 or chromosomes and genes.
