Near-chromosome level genome assembly of the fruit pest Drosophila suzukii using long-read sequencing.

Over the past decade, the spotted wing Drosophila, Drosophila suzukii, has invaded Europe and America and has become a major agricultural pest in these areas, thereby prompting intense research activities to better understand its biology. Two draft genome assemblies already exist for this species but contain pervasive assembly errors and are highly fragmented, which limits their values. Our purpose here was to improve the assembly of the D.

Deciphering the Wisent Demographic and Adaptive Histories from Individual Whole-Genome Sequences.

As the largest European herbivore, the wisent (Bison bonasus) is emblematic of the continent wildlife but has unclear origins. Here, we infer its demographic and adaptive histories from two individual whole-genome sequences via a detailed comparative analysis with bovine genomes. We estimate that the wisent and bovine species diverged from 1.

Genome analysis of Minibacterium massiliensis highlights the convergent evolution of water-living bacteria.

Filtration usually eliminates water-living bacteria. Here, we report on the complete genome sequence of Minibacterium massiliensis, a beta-proteobacteria that was recovered from 0.22-mum filtered water used for patients in the hospital.

The genome sequence of Rickettsia felis identifies the first putative conjugative plasmid in an obligate intracellular parasite.

We sequenced the genome of Rickettsia felis, a flea-associated obligate intracellular alpha-proteobacterium causing spotted fever in humans. Besides a circular chromosome of 1,485,148 bp, R. felis exhibits the first putative conjugative plasmid identified among obligate intracellular bacteria.
