AbstractWe report the complete genome sequence of a field isolate of a novel bipartite secovirid infecting cassava in Colombia, provisionally named "cassava torrado-like virus" (CsTLV). The genome sequence was obtained using Oxford Nanopore Technology, and the 5’ ends were confirmed by RACE. The RNA1 is 7252 nucleotides (nt) long, encoding a polyprotein of 2336 amino acids (aa) containing the typical “replication block”, conserved torradovirus motifs, and a Maf/Ham1 domain, which is not commonly found in viral genomes. The RNA2 is 4469 nt long and contains two overlapping ORFs encoding proteins of 226 and 1179 aa, showing the characteristic genome arrangement of members of the genus Torradovirus.

Microorganisms serve as attractive resources, owing to their ability to synthesize structurally-diverse substanceswith various bioactivities. Within the Bacteria domain, members of the genus Streptomyces have demonstrated remarkableability to produce clinically useful, secondary metabolites such as anticancer, antioxidants, antivirals and antibacterials.Streptomyces pluripotens MUSC 135T was isolated as novel strain from mangrove forest in Malaysia. This strain exhibitedbroad spectrum bacteriocin against several pathogens including methicillin-resistant Staphylococcus aureus (MRSA) strainATCC BAA-44, Salmonella typhi ATCC 19430T and Aeromonas hydrophila ATCC 7966T. Thus, the strain was selected forwhole genome sequencing as an attempt to explore its bioactive potential. Here we report the first complete genome of S.pluripotens MUSC 135T genome which comprise of 7.35 Mbp with G+C content of 69.9 %. A total of 6,404 open readingframes (ORFs) were predicted, along with 18 rRNA and 69 tRNA genes. Using bacteriocin mining tool, BAGEL detectedeights gene clusters associated with bacteriocin production including lanthipeptides and linear azol(in)e-containing peptides(LAPs). Members of Streptomyces have contributed greatly towards improving lives, particularly against deadly infectionsand chronic diseases. The availability of S. pluripotens MUSC 135T genome sequence has opened new window for drugdiscovery, particularly for effective drugs against harmful pathogens such as MRSA and certainly deserves further detailedstudy.
