ABSTRACT Phytoplasmas are bacterial plant pathogens with devastating impact on agricultural production worldwide. In eastern Africa, Napier grass stunt disease causes serious economic losses in the smallholder dairy industry. This draft genome sequence of “ Candidatus Phytoplasma oryzae” strain Mbita1 provides insight into its genomic organization and the molecular basis of pathogenicity.

ABSTRACT “ Candidatus Berkiella cookevillensis” and “ Candidatus Berkiella aquae” are obligate intranuclear endosymbionts of freshwater amoebae. Here, we present the draft genome sequences of these two bacteria, with total sizes of 2,990,361 bp and 3,626,027 bp, respectively.

ABSTRACT Two bacterial symbionts of the European pest leafhopper, Macrosteles quadripunctulatus (Hemiptera: Cicadellidae), were fully sequenced. “ Candidatus Sulcia muelleri” and “ Ca . Nasuia deltocephalinicola” represent two of the smallest known bacterial genomes at 190 kb and 112 kb, respectively. Genome sequences are nearly identical to strains reported from the closely related host species, M. quadrilineatus .

ABSTRACT Here, we present the draft genome of “ Candidatus Methanomethylophilus” sp. 1R26, a member of the newly described Methanomassiliicoccales order of Euryarcheaota . The enrichment culture was established from bovine rumen contents and produced methane from trimethylamine and methanol. The draft genome contains genes for methanogenesis from methylated compounds.

ABSTRACT Here we present the draft genome of a distantly related member within the phylum Bacteriodetes , “ Candidatus Bacteroides periocalifornicus .” The draft genome sequence was assembled with metagenomic data from a patient with periodontitis. The closest relative has less than 68% average nucleic identity, supporting a novel family within Bacteriodetes .

ABSTRACT The draft genome sequence of “ Candidatus Liberibacter asiaticus” strain YCPsy from an Asian citrus psyllid ( Diaphorina citri ) in Guangdong, China, is reported here. The YCPsy strain has a genome size of 1,233,647 bp, 36.5% G+C content, 1,171 open reading frames (ORFs), and 53 RNAs.

ABSTRACT The genome of “ Candidatus Profftella armatura” strain YCPA from Diaphorina citri in Guangdong, China, was sequenced. The strain has a chromosome of 457,565 bp, 24.3% G+C content, 364 predicted open reading frames (ORFs), and 38 RNAs, and a plasmid, pYCPA54, of 5,458 bp with 23.9% G+C content and 5 ORFs.

ABSTRACT The draft genome sequence of “ Candidatus Liberibacter asiaticus” strain SGCA5 from an orange citrus tree in San Gabriel, California, is reported here. SGCA5 has a genome size of 1,201,445 bp, a G+C content of 36.4%, 1,152 predicted open reading frames (ORFs), and 42 RNA genes.

ABSTRACT The draft genome sequence of “ Candidatus Liberibacter solanacearum” strain RSTM from a potato psyllid ( Bactericera cockerelli ) in California is reported here. The RSTM strain has a genome size of 1,286,787 bp, a G+C content of 35.1%, 1,211 predicted open reading frames (ORFs), and 43 RNA genes.

ABSTRACT “ Candidatus Phytoplasma pruni” strain CX, belonging to subgroup 16SrIII-A, is a plant-pathogenic bacterium causing economically important diseases in many fruit crops. Here, we report the draft genome sequence, which consists of 598,508 bases, with a G+C content of 27.21 mol%.
