Circular genome of strain NCD-2 with specific features. The circular genome map was created using Circos v0.66 with COG (Cluster of Orthologous Groups of proteins) function annotation. From outside to inside: circle 1, the size of the complete genome; circles 2 and 3, the predicted protein-coding genes on the + and - strands, respectively, where different colours represent different COG function classifications; circle 4, tRNA (green) and rRNA (red); circle 5, G + C content, where peaks outside/inside the circle indicate above or below average GC content, respectively; the inner circle, G + C skew, with G% < C% in purple and with G% > C% in blue. The potato dextrose agar plate inside the representation of the circular genome shows the antifungal activity of strain NCD-2 and its derived strain constructed by atmospheric and room temperature plasma (ARTP) against Botrytis cinerea. The black bars outside the circular genome indicate the secondary metabolite biosynthetic gene clusters
