Abstract
V originále
LTR retrotransposons are mobile genetic elements which play significant role in plant genome structure, organization, and evolutionary dynamics. Holocentricity represents an unusual and distinct genome organization type which has independently arisen at least five times in Angiosperms. Expanded distribution of centromeric units in holocentrics affects the landscape of many genomic and epigenomic features. Our work shows how centromere organization type affects evolutionary footprints of LTR retrotransposon activation, targeting (insertion to specific chromosomal regions or to other LTR retrotransposons), and degradation by analysing element abundance, position, insertion time, nesting, and elimination (presence of solo-LTRs) in plants from Juncaceae family — monocentric Juncus effusus and holocentric Luzula sylvatica. Analysis of this special type of chromosomes allows us to better understand the factors and mechanisms forming genomic landscape in plants.
