Characterization of a new high copy Stowaway family MITE, BRAMI-1 in Brassica genome.

ABSTRACT:

Background

Miniature inverted-repeat transposable elements (MITEs) are expected to play important roles in evolution of genes and genome in plants, especially in the highly duplicated plant genomes. Various MITE families and their roles in plants have been characterized. However, there have been fewer studies of MITE families and their potential roles in evolution of the recently triplicated Brassica genome.

Results

We identified a new MITE family, BRAMI-1, belonging to the Stowaway super-family in the Brassica genome. In silico mapping revealed that 697 members are dispersed throughout the euchromatic regions of the B. rapa pseudo-chromosomes. Among them, 548 members (78.6%) are located in gene-rich regions, less than 3 kb from genes. In addition, we identified 516 and 15 m
