Hobrac: a reference-guided workflow for genome comparison and synteny visualization

Whole-genome comparison is fundamental for validating genome assemblies and investigating genome evolution, yet identifying suitable reference genomes and interpreting chromosome-scale synteny from often noisy nucleotide alignments remain challenging. We introduce Hobrac, an automated workflow that addresses these two major bottlenecks by combining automated reference genome selection with gene-based structural comparisons. Starting from a genome assembly and its taxon identifier, Hobrac identifies suitable reference genomes, complements nucleotide alignments with conserved BUSCO orthologues, and generates publication-quality visualizations. The workflow produces dotplots, ribbon-plots and synteny visualization that can be explored interactively or offline. Hobrac is freely available at https://github.com/Genoscope-LBGB/hobrac.

ERGA-BGE genome of Noah's Ark shell (Arca noae Linnaeus, 1758), a Mediterranean bivalve species

Arca noae, also known as the Noahs Ark clam, is a bivalve mollusk found in the shallow coastal waters of the Mediterranean Sea and the eastern Atlantic Ocean. This species plays a crucial ecological role by filtering plankton and organic particles from the water, helping maintain water quality and supporting nutrient cycling in marine ecosystems. It is also an important food source for various marine predators, including fish and crustaceans, thereby contributing to the coastal food web. Arca noae is notably resilient to environmental stressors, such as temperature fluctuations, changes in salinity, and pollution, making it a valuable model species for studying how bivalves adapt and respond to stress. While it is not commonly harvested commercially, Arca noae is of great interest to marine researchers due to its ability to thrive in diverse coastal habitats. The reference genome of Arca noae will thus provide important evolutionary insights. The entirety of the genome sequence was assembled into 19 contiguous chromosomal pseudomolecules. This chromosome-level assembly encompasses 1.5 Gb, composed of 257 contigs and 119 scaffolds, with contig and scaffold N50 values of 20.5 Mb and 84.7 Mb, respectively.

ERGA-BGE genome of Androsace saussurei Dentant, Lavergne, F. C. Boucher & S. Ibanez, a recently described plant from the rooftops of Europe

The reference genome of Androsace saussurei (Ericales: Primulaceae: Primuloideae) provides a valuable resource for understanding the mechanisms of plant adaptations to the most extreme environments where flowering plants can thrive and the speciation mechanisms of plants dwelling on high alpine sky islands. The entirety of the genome sequence was assembled into 20 contiguous chromosomal pseudomolecules. This chromosome-level assembly encompasses 413 Mb, composed of 253 contigs and 101 scaffolds, with contig and scaffold N50 values of 4.95 Mb and 21.2 Mb, respectively.
