Genome resource of Streptomyces atratus PY-1, a broad-spectrum antimicrobial strain in particular antagonistic against Plasmopara viticola.

Streptomyces atratus PY-1 exhibited promising antimicrobial properties, in particular it is highly inhibitory to Plasmopara viticola, which causes downy mildew of grape. It is very necessary to carry out systematic and in-depth research on PY-1 strain for the improvement, application and promotion of biocontrol agents. The PY-1 genome was fully sequenced and assembled. We present the draft genome sequence of PY-1, with a size of 9, 254, 781 bp. Preliminary analysis on the PY-1 genome sequence shows that at least 35 gene clusters are involved in the biosynthesis of polyketides, terpenes and nonribosomally synthesized peptides.
