Goosegrass, belonging to the genus Eleusine within the Chloridoideae subfamily, is often one of the problematic weeds with strong invasiveness, competing with crops for essential survival resources. Although a chromosome-level genome assembly of E. indica from China was published last year, the present research focuses on a population of E. indica native to South Korea. Considering the high genetic variability among wild E. indica populations, constructing multi-reference genomes from geographically distinct populations is crucial for comprehensive weed management strategies. In this study, we sequenced and assembled the whole genome using PacBio long read and Illumina short read sequencing platforms. We then combined Pore-C sequencing technology to successfully anchor 255 contigs to nine pseudochromosomes. The chromosome-level genome assembly showed a high level of completeness with a 97% score according to BUSCO analysis results. Repetitive sequences accounted for 97% of the genome assembly, and 26,836 protein-coding genes were predicted. The high-quality genome assembly of E. indica will serve as a valuable genetic resource to enhance our understanding of weed control research.

Arctic ground squirrels () hibernate for several months without eating or drinking yet suffer no disuse atrophy. We are investigating the potential contributions of gut microorganisms to host nitrogen homeostasis, and here, we describe the genome assemblies of 35 isolated bacteria collected from gastrointestinal material and sequenced using Nanopore technology.

Basil, Ocimum basilicum L., is a widely cultivated aromatic herb, prized for its culinary and medicinal uses, predominantly owing to its unique aroma, primarily determined by eugenol for Genovese cultivars or methyl chavicol for Thai cultivars. To date, a comprehensive basil reference genome has been lacking, with only a fragmented draft available.

Here we considered models for esophageal adenocarcinoma (EAC), a cancer that has dramatically increased in incidence over the past few decades in Western populations, with high case fatality rates due to late-stage diagnoses. Despite advancements in genomic analyses of the precursor Barrett's esophagus (BE), prevention of late-stage EAC remains a significant clinical challenge.

Since the publication of its draft genome in 2007, the genome has drawn attention for several reasons, including its unusually large size, massive expansion of gene families, and high repeat content. The fragmented nature of the draft assembly made it challenging to obtain accurate metrics of features, such as spliceosomal introns.

Whether and how frequently that resistance occurred before the introduction is harder to determine, as isolates could not have been tested for resistance before an antibiotic was discovered. Historical collections, like the British National Collection of Type Cultures (NCTC), stretching back to 1885, provide a window into this history.
