A significant portion of eukaryotic genomes consists of non-coding repetitive DNA sequences arranged in tandem arrays, known as satellite DNA (satDNA) [...

The Genome of the Yellow Mealworm, : It's Bigger Than You Think.

Background: Insects are a sustainable source of protein for human food and animal feed. We present a genome assembly, CRISPR gene editing, and life stage-specific transcriptomes for the yellow mealworm, , one of the most intensively farmed insects worldwide.

Methods: Long and short reads and long-range data were obtained from a male pupa.

The Low-Copy-Number Satellite DNAs of the Model Beetle .

The red flour beetle is an important pest of stored agricultural products and the first beetle whose genome was sequenced. So far, one high-copy-number and ten moderate-copy-number satellite DNAs (satDNAs) have been described in the assembled part of its genome. In this work, we aimed to catalog the entire collection of satDNAs.

Satellite DNAs-From Localized to Highly Dispersed Genome Components.

According to the established classical view, satellite DNAs are defined as abundant non-coding DNA sequences repeated in tandem that build long arrays located in heterochromatin. Advances in sequencing methodologies and development of specialized bioinformatics tools enabled defining a collection of all repetitive DNAs and satellite DNAs in a genome, the repeatome and the satellitome, respectively, as well as their reliable annotation on sequenced genomes. Supported by various non-model species included in recent studies, the patterns of satellite DNAs and satellitomes as a whole showed much more diversity and complexity than initially thought.

Satellitome analyses in nematodes illuminate complex species history and show conserved features in satellite DNAs.

Background: Satellite DNAs (satDNAs) are tandemly repeated non-coding DNA sequences that belong to the most abundant and the fastest evolving parts of the eukaryotic genome. A satellitome represents the collection of different satDNAs in a genome. Due to extreme diversity and methodological difficulties to characterize and compare satDNA collection in complex genomes, knowledge on their putative functional constraints and capacity to participate in genome evolution remains rather elusive.
