Circular map of the Bacillus amyloliquefaciens SQR9 genome. The gene expression profiles in response to maize root exudates are also shown. 1^st circle: all genes in color code according to function: orange, information storage and processing; green, cellular processes and signaling; purple, metabolism; red, poorly characterized, red; gray, unknown; 2^nd and 3^rd circle: gene expression responses to root exudates after inoculation for 24 h and 48 h, respectively; 4^th circle: the numbered 11 DNA islands (green); 5^th circle: rRNAs (orange) and tRNAs (blue); 6^th circle: prophages (green) and IS elements (red); 7^th circle: GC content; 8^th circle: GC skew. The highlighted area of gray is a conserved genomic island of SQR9, and the green area is a shared prophage with Bacillus subtilis 168
