, a necrotrophic fungal pathogen, causes Alternaria blight, an important disease of brassica crops. Although many spp. have been sequenced, no genome information is available for , a monotypic lineage within the genus. A highly contiguous genome assembly of has been generated using Nanopore MinION sequencing with an N50 of 2.98 Mb, yielding nine full chromosome-level sequences. This study adds to the current genomic resources available for the genus and will provide opportunities for further analyses to unravel the mechanisms underlying pathogenicity of this important necrotrophic pathogen.

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.

This study aimed to investigate the dissemination of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in water samples obtained during the coronavirus disease 2019 pandemic period, employing cross-assembly phage (crAssphage) as a fecal contamination biomarker and next-generation sequencing protocols to characterize SARS-CoV-2 variants. Raw wastewater and surface water (stream and sea) samples were collected for over a month in Rio de Janeiro, Brazil. Ultracentrifugation and negatively charged membrane filtration were employed for viral concentration of the wastewater and surface water samples, respectively.

The Asian icefish, Protosalanx chinensis, has undergone extensive colonization in various waters across China for decades due to its ecological and physiological significance as well as its economic importance in the fishery resource. Here, we decoded a telomere-to-telomere (T2T) genome for P. chinensis combining PacBio HiFi long reads and ultra-long ONT (nanopore) reads and Hi-C data.

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.
