| Summary: | These datasets correspond to sequencing of DNA and RNA extracted from surface-disinfected teliospores of the fungus Thecaphora frezzii Carranza and Lindquist, causal agent of smut disease in peanut (Arachis hypogaea L.). The DNA was sequenced using Pacific Biosciences (PacBio) Sequel II and RNA was sequenced in Illumina MiSeq 300 bp paired end (PE). Initial de novo assembly and Basic Local Alignment Search Tool (BLAST) of contigs to the 16S reference sequence database at NCBI had hits on seven bacterial species: Luteibacter pinisoli, Variovorax paradoxus, Rhizobium metallidurans, Caulobacter segnis, Roseateles violae, Novosphingobium rosa, Herbaspirillum seropedicae, and the fungus T. frezzii. High stringency mapping of the RNA sequences to the genomes of these organisms showed that 96% of the reads corresponded to bacteria and only 4% to T. frezzii. De novo assembly of PacBio reads revealed the whole genome of a Luteibacter sp. with 88.56% or lower similarity to those in NCBI database, whereas most RNA sequences (> 10 million reads) mapped to the new Luteibacter sp. genome assembled here. We annotated the new Luteibacter sp. genome, assessed its completeness by BUSCO, and aligned it to its closest relative, Luteibacter aegosomatissinici. We are not aware of any report that describes bacteria colonizing teliospores of T. frezzii. The DNA and RNA sequencing datasets provided here could be used to study the distribution of prokaryotes colonizing T. frezzii teliospores, and to explore the role of the microbiome of T. frezzii teliospores on the outcome of peanut smut disease. |
