Genetics

The hypervariable genomic regions derived from 35 published C Las genomes were used to decipher the genetic diversity of C Las strains and identify 10 new strains with high variations in prophage regions. Characterizing these variations in the C Las bacteria might provide insight into their evolution and adaptation to host plants and insects in China.

The DPANN superphylum is a group of archaea widely distributed in various habitats. They generally have small cells and have a symbiotic lifestyle with other archaea.

Here, we report metagenome-assembled genomes for “ Candidatus Phormidium sp. strain AB48” and three cooccurring microorganisms from a biofilm-forming industrial photobioreactor environment, using the PacBio sequencing platform. Several mobile genetic elements, including a double-stranded DNA phage and plasmids, were also recovered, with the potential to mediate gene transfer within the biofilm community.

Illumina sequencing of a Prunus avium tree with X-disease symptoms was performed to obtain a draft genome of “ Candidatus Phytoplasma pruni.” The genome consists of 14 contigs covering 588,767 bp. This is the first metagenome to be sequenced from the current X-disease epidemic in stone fruit in the Pacific Northwest.
