The genome of “ Candidatus Sulcia muelleri” strain KPTW1 from Kolla paulula , a vector of Xylella fastidiosa that causes Pierce’s disease (PD) of grapevine in Taiwan, was sequenced. The strain has a genome size of 253,942 bp, GC content of 22.7%, 237 predicted protein-coding genes, and 34 RNA genes.

We report here the near-complete genome sequence of “ Candidatus Spirobacillus cienkowskii,” a spiral-shaped, red-pigmented uncultivated bacterial pathogen of Daphnia spp. The genome is 2.74 Mbp in size, has a GC content of 32.1%, and contains genes associated with bacterial motility and the production of carotenoids, which could explain the distinctive red color of hosts infected with this pathogen.

Metagenomic sequencing of fracture fluid from South Africa recovered a nearly complete “ Candidatus Bathyarchaeota” archaeon genome. The metagenome-assembled genome of BE326-BA-RLH contains genes involved in methane metabolism and dissimilatory nitrate reduction.

The Tara Oceans Consortium has published various metagenomes of marine environmental samples. Here, we report a contig of 2.6 Mbp from the assembly of a sample collected near the Marquesas Islands in the Pacific Ocean, covering a nearly complete novel verrucomicrobial genome.

A draft genome sequence is presented for a strain of “ Candidatus Phytoplasma asteris” affecting canola plants in Saskatoon, Canada. This phytopathogenic bacterium was determined to be a 16SrI strain and features 16S rRNA-encoding gene sequence heterogeneity.

Here, we report the draft genome sequence of “ Candidatus Izimaplasma sp.” strain ZiA1 (1.88 Mb and 29.6% G+C content).
