Red claw crayfish (Cherax quadricarinatus) is an aquatic crustacean with considerable potential for the commercial culture and an ideal model for studying the mechanism of sex determination. To provide better genomic resources, we assembled a chromosome-level genome with a size of 5.26 Gb and contig N50 of 144.33 kb. Nearly 90% of sequences were anchored to 100 chromosomes, which represents the high-quality crustacean genome with the largest number of chromosomes ever reported. The genome contained 78.69% repeat sequences and 20,460 protein-coding genes, of which 82.40% were functionally annotated. This chromosome-scale genome would be a valuable reference for assemblies of other complex genomes and studies of evolution in crustaceans.

Metabolic enhancement contributed by horizontal gene transfer is essential for dietary specialization in leaf beetles.

Horizontal gene transfer (HGT) from bacteria to insects is widely reported and often associated with the adaptation and diversification of insects. However, compelling evidence demonstrating how HGT-conferred metabolic adjustments enable species to adapt to surrounding environment remains scarce. Dietary specialization is an important ecological strategy adopted by animals to reduce inter- and intraspecific competition for limited resources.

Background: A thorough analysis of genome evolution is fundamental for biodiversity understanding. The iconic monotremes (platypus and echidna) feature extraordinary biology. However, they also exhibit rearrangements in several chromosomes, especially in the sex chromosome chain.

Emberiza buntings (Aves: Emberizidae) exhibit extensive diversity and rapid diversification within the Old World, particularly in the eastern Palearctic, making them valuable models for studying rapid radiation among sympatric species. Despite their ecological and morphological diversity, there remains a significant gap in understanding the genomic underpinnings driving their rapid speciation. To fill this gap, we assembled high-quality chromosome-level genomes of five representative Emberiza species (E.

Small Leucine-Rich Proteoglycans (SLRPs) are a major family of vertebrate proteoglycans. In bony vertebrates, SLRPs have a variety of functions from structural to signaling and are found in extracellular matrices, notably in skeletal tissues. However, there is little or no data on the diversity, function and expression patterns of SLRPs in cartilaginous fishes, which hinders our understanding of how these genes evolved with the diversification of vertebrates, in particular regarding the early events of whole genome duplications that shaped gnathostome and cyclostome genomes.
