Circular genome plot. Ring definitions, from outermost to innermost: Predicted proteins colored by reading frame on the plus strand (red, green, blue are forward frames); predicted proteins colored by reading frame on the minus strand (cyan, magenta, and yellow are reverse frames); RNA coding features (red: tRNAs; blue: rRNAs; magenta: RNAse P RNA; green: tmRNA; cyan: 4.5S SRP RNA); GC content (calculated using a 5000-bp window sliding 100 bases at a time, see plot for range, height of trace proportional to deviation from 25% GC); cumulative GC-skew (calculated using a 5000-bp window sliding 100 bases at a time, see plot for range, height of trace proportional to deviation from 0) as in Grigoriev (1998).
