| Popis | LTR retrotransposons play a significant role in plant genome structure, organization, and evolutionary dynamics. Holocentricity represents an unusual and distinct genome organization type affecting many genomic processes and characteristics, nonetheless, the specifics of the interplay with LTR retrotransposons in these genomes remain largely unexplored. We present the analysis of LTR transposable elements in several species of holocentric plants from the Cyperaceae and Juncaceae families. Holocentric and monocentric plant species were selected to represent a broad spectrum of genome sizes and chromosome numbers. Their genomic DNA was sequenced using a combination of long and short reads. This data was used to analyze the overall type and abundance of repetitive sequences in genomes and to identify transposable elements in partial genomic assemblies. Detected LTR retrotransposons were then investigated to characterize their lineage, age, completeness, and nested insertions. |
