Long terminal repeat (LTR) type retrotransposons in Populus species: a uniquely abundant and informative class of molecular markers for forest biotechnology
2005
Potter, S.
This paper describes a preliminary study to establish the utility of a retrotransposon development program for an industrially relevant forest tree species. The poplar genome harbours several thousand copies of LTR type retrotransposons, a type of uniquely useful molecular marker for studying the evolution of genomes. Many of the sequences identified were associated with key genes involved in wood formation and disease resistance, illustrating a critical advantage of the use of retrotransposons as markers in molecular breeding. Several other potential applications for retrotransposons in genome assembly, genome variation studies and in the tagging and functional analysis of genes are also discussed.
