DOI: 10.1038/s41467-019-13355-3
Abstract: The abundant repetitive sequences in complex eukaryotic genomes cause fragmented assemblies, which lose value as reference genomes, often due to incomplete gene sequences and unanchored or mispositioned contigs on chromosomes. Here we report a genome… read more here.

DOI: 10.1073/pnas.2321859121
Abstract: Significance Repetitive DNA sequences in the genome can cause problems for our cells. To protect the genome, cells turn off these repetitive sequences by placing them in inactive heterochromatic areas and adding repressive markers. However,… read more here.

The role of repetitive sequences in re-patterning of major rDNA clusters in Lepidoptera.

DOI: 10.1093/gbe/evad090
Abstract: Genes for major ribosomal RNAs (rDNA) are present in multiple copies mainly organized in tandem arrays. Number and position of rDNA loci can change dynamically and their re-patterning is presumably driven by other repetitive sequences.… read more here.

DOI: 10.1093/gigascience/giaf047
Abstract: Abstract Background The genus Ormosia belongs to the Fabaceae family; almost all Ormosia species are endemic to China, which is considered one of the centers of this genus. Thus, genomic studies on the genus are… read more here.

DOI: 10.1109/tvcg.2020.2992670
Abstract: We introduce a technique to synthetically increase the framerate of semi-repetitive videos (i.e., videos of motion that repeats but not in an identical fashion) to aid in visualization. By reordering and combining frames from all… read more here.

DOI: 10.1139/gen-2021-0129
Abstract: Leaf-cutting ants are among the New World's most conspicuous and studied ant species due to their notable ecological and economic role. Cytogenetic studies carried out in Atta show remarkable karyotype conservation among the species. We… read more here.

DOI: 10.1186/s13104-018-3298-5
Abstract: ObjectiveRepeat expansion of polyglutamine tracks leads to a group of inherited human neurodegenerative disorders. Studying such repetitive sequences is required to gain insight into the pathophysiology of these diseases. PCR-based manipulation of repetitive sequences, however,… read more here.
