Abstract EN
Chromodomain-containing LTR retrotransposons are one of the most successful groups of mobile elements in plant genomes.
Previously, we demonstrated that two types of chromodomains (CHDs) are carried by plant LTR retrotransposons.
Chromodomains from group I (CHD_I) were detected only in Tcn1-like LTR retrotransposons from nonseed plants such as mosses (including the model moss species Physcomitrella) and lycophytes (the Selaginella species).
LTR retrotransposon chromodomains from group II (CHD_II) have been described from a wide range of higher plants.
In the present study, we performed computer-based mining of plant LTR retrotransposon CHDs from diverse plants with an emphasis on spike-moss Selaginella.
Our extended comparative and phylogenetic analysis demonstrated that two types of CHDs are present only in the Selaginella genome, which puts this species in a unique position among plants.
It appears that a transition from CHD_I to CHD_II and further diversification occurred in the evolutionary history of plant LTR retrotransposons at approximately 400 MYA and most probably was associated with the evolution of chromatin organization.
