“…Transposable elements (TEs) constitute a significant proportion of the eukaryotic genome and play key biological and evolutionary roles. The interactions between TEs and their hosts were discussed in a series of meetings titled "Biological Function and Evolution through Interactions between Hosts and Transposable Elements" [1][2][3]. This meeting was held at the National Institute of Genetics (NIG), Mishima, Japan, where biologists studying TEs in different species gathered and exchanged ideas.…”

The sixth Japanese meeting on host–transposon interactions, titled “Biological Function and Evolution through Interactions between Hosts and Transposable Elements,” was held on August 24th and 25th, 2023, at the National Institute of Genetics as well as online. This meeting was supported by the National Institute of Genetics and aimed to bring together researchers studying the diverse roles of TEs in genome function and evolution, as well as host defense systems against TE mobility, TE bursts during evolution, and intron mobility in mammals, insects, land plants, yeast, protozoa, and bacteria. Here, we have presented the highlights of the discussion.Organizers: Kenji Ichiyanagi, Yoko Ikeda, and Kuniaki Saito.

The fifth Japanese meeting on host–transposon interactions, titled “Biological Function and Evolution through Interactions between Hosts and Transposable Elements (TEs),” was held online on August 26–27, 2021. The meeting was supported by National Institute of Genetics and aimed to bring together researchers studying the diverse roles of TEs in genome function and evolution, as well as host defense systems against TE mobility by chromatin and RNA modifications and protein-protein interactions. Here, we present the highlights of the talks.

The subgenus Cerasus and its relatives include many crucial economic drupe fruits and ornamental plants. Repetitive elements make up a large part of complex genomes, and some of them play an important role in gene regulation that can affect phenotypic variation. However, the variation in their genomes remains poorly understood. This work conducted a comprehensive repetitive sequence identification across the draft genomes of eight taxa of the genus Prunus, including four of the Prunus subgenus Cerasus (Prunus pseudocerasus, P. avium, P. yedoensis and P. × yedoensis) as well as congeneric species (Prunus salicina, P. armeniaca, P. dulcis and P. persica). Annotation results showed high proportions of transposable elements in their genomes, ranging from 52.28% (P. armeniaca) to 61.86% (P. pseudocerasus). The most notable differences in the contents of long terminal repeat retrotransposons (LTR-RTs) and tandem repeats (TRs) were confirmed with de novo identification based on the structure of each genome, which significantly contributed to their genome size variation, especially in P. avium and P.salicina. Sequence comparisons showed many similar LTR-RTs closely related to their phylogenetic relationships, and a highly similar monomer unit of the TR sequence was conserved among species. Additionally, the predicted centromere-associated sequence was located in centromeric regions with FISH in the 12 taxa of Prunus. It presented significantly different signal intensities, even within the diverse interindividual phenotypes for Prunus tomentosa. This study provides insight into the LTR-RT and TR variation within Prunus and increases our knowledge about its role in genome evolution.
