Abstract

Terminal-repeat retrotransposon in miniature (TRIM) elements are a miniature form of retrotransposons and play an important role in genome organization. The Cassandra TRIM family has been identified in over 50 plant species, including both monocots and dicots. Cassandra elements carry an independently transcribed 5S RNA sequence in their terminal repeat regions, which is unique compared with other TRIM families. Although the existence of Cassandra elements has been documented in many plants, much work remains to characterize Cassandra family members and elucidate their distribution. In this study, we comparatively analysed the Cassandra family members in the Brassica oleracea, B. rapa and Arabidopsis thaliana genomes. A total of 602, 451 and 173 members, of which 130, 60 and 9 were relatively intact, were identified from the B. oleracea, B. rapa and A. thaliana genomes, respectively. Most of the Cassandra elements (1120/1226) were found in intergenic spaces, but 106 elements were inserted in genic regions such as introns, exons and untranslated regions. Our comparative analysis of the Cassandra family members in A. thaliana, B. rapa and B. oleracea reveals that some Cassandra elements have been commonly retained during the last 20 million years in three species and some elements have been uniquely evolved in Brassica species. This study promotes our understanding of the role and utility of Cassandra elements in the evolution of the Brassicaceae family.
