Circular representation of the chromosome and plasmids of strain 4834-R of X. fuscans subsp. fuscans . From outside to inside, circle 1 indicates the localization of the various secretion systems (T1SS to T6SS), type I pilus (T1p), type IV pilus (T4p), elements devoted to cell protection (exopolysaccharides, lipopolysaccharides), chemotaxis and motility. Circle 2 indicates the localization of type III effectectors (T3Es), and circle 3 indicates the localization of instertion sequences (ISs). The black circle shows the G + C content using a 100-base window. The green and purple circle shows the GC skew (G-C)/(G + C) using a 100-base window.
