Abstract
‘Candidatus Phytoplasma’ is an uncultivated, intracellular bacterial plant pathogen transmitted by phloem-feeding insect vectors. Among the group of phytoplasmas, the Peanut Witches' Broom or 16SrII group of phytoplasmas associated with various diseases cause severe crop losses every year in India. The ‘Ca. Phytoplasma sp.’ strain SS02 was associated with phyllody disease of sesame plants collected from New Delhi. The genome sequence of strain SS02 was obtained using its genomic DNA enrichment and hybrid assembly of sequences generated on Illumina and Oxford Nanopore Technologies MinION platforms. The hybrid assembly strategy generated a draft genome with 60 contigs totaling 553,228 bp of length with more than 400 × depth coverage and 95.21% of the estimated completeness. The SS02 genome draft sequence contains 465 protein-coding genes, 17 tRNA genes, and 3 rRNA genes. The availability of this draft genome also provided a foundation for genome-scale genotypic analyses.
Data availability
The Whole Genome Shotgun sequence for strain SS02 have been deposited in the DDBJ/ENA/GenBank database under accession numbers JAHBAJ000000000. The version described in this paper is JAHBAJ020000000 under the BioSample ID SAMN19066185 and BioProject ID PRJNA727971.
