Escherichia coli C is a commonly used strain in the bioprocessing industry, but despite its utility, the publicly available sequence of the E. coli C genome has gaps and 4,180 ambiguous base calls. Here, we present an updated, high-quality, unambiguous genome sequence with no assembly gaps.

Pear-Shaped Eggs Evolved to Maximize the Surface Area-to-Volume Ratio, Increase Metabolism, and Shorten Incubation Time in Birds.

Bird eggs can be spherical, ellipsoid, ovoid, or pear-shaped (pyriform), the latter being the most complex. There is however no unambiguous evolutionary/adaptive explanation for this final, exotic shape. We hypothesized that pyriform eggs have a larger surface area-to-volume ratio (S/V) that may be a criterion for increased embryo metabolism.

Background: The Human Genome Variation Society (HGVS) Nomenclature is the global standard for describing and communicating variants in DNA, RNA, and protein sequences in clinical and research genomics. This manuscript details recent updates to the HGVS Nomenclature, highlighting improvements in governance, community engagement, website functionality, and underlying implementation of the standard.
Methods: The HGVS Variant Nomenclature Committee (HVNC) now operates under the Human Genome Organization (HUGO), facilitating broader community feedback and collaboration with related standards organizations.

Multi-locus sequence typing (MLST) based on eight genes has become the method of choice for Borrelia typing and is extensively used for population studies. Whole-genome sequencing enables studies to scale up to genomic levels but necessitates extended schemes. We have developed a 639-loci core genome MLST (cgMLST) scheme for Borrelia burgdorferi sensu lato (s.

Article Synopsis
- Huanglongbing (HLB) disease, triggered by the bacterium Liberibacter asiaticus, poses a serious threat to citrus production with no existing cure, making the development of resistant cultivars essential.
- Researchers focused on the NONEXPRESSOR OF PATHOGENESIS-RELATED GENES (NPR) family, specifically modifying NPR1 and NPR3 genes in sweet orange trees to improve HLB resistance.
- The genome-edited sweet orange varieties showed enhanced vigor compared to wild-type trees under greenhouse conditions, suggesting that targeted gene editing can help in developing HLB-tolerant citrus plants, although further field tests are required to confirm these results.

Small noncoding RNAs (sncRNAs) can regulate gene expression by guiding the RNA-induced silencing complex (RISC) to targeted transcripts for translational repression and/or target destabilization. Here, we present a robust benchtop protocol, termed CIMERA-seq, for the unambiguous profiling of sncRNA:target RNA interactions in a genome-wide and cell-type-selective manner. We describe steps for in vivo crosslinking and harvesting tissue, immunoprecipitation and covalent ligation of sncRNAs to target RNAs within the RISC, and sequencing of the resulting chimeric sncRNA:target RNA interactions.
