Diversity of type III secretome in Xanthomonas campestris. a Presence (blue)/absence (white) matrix of genes encoding putative T3SP including T3E (black font) and other accessory proteins (others; grey font) was searched in genomic sequences by tblastn using known T3SP protein sequences (http://www.xanthomonas.org/t3e.html). X. campestris core T3E are indicated in red. Grey and blue boxes correspond to protein identities ranging from 40-60 % and 60-100 % over the entire length of the reference protein. Numbers indicate copy numbers of hax genes. The minimal size of the secretome is indicated below the table. b Venn diagram illustrating the overlap between the core secretomes of X. campestris pathovars: campestris (Xcc), non-pathogenic (XcNP), incanae (Xci) and raphani (Xcr). Numbers in brackets indicate the number of the core and accessory type III secreted proteins as inferred from published genome sequences in those pathovars. Genes orthologous to known type III secreted proteins (www.xanthomonas.org) were identified by Blast. Asterisk indicates that all predicted type III secreted proteins of strain CFBP 5825R were used in this analysis. Xcc: X. campestris pv. campestris, Xci: X. campestris pv. incanae, Xcr: X. campestris pv. raphani, XcNP: X. campestris non-pathogenic
