Detailed information on the strains of X. arboricola analyzed in the work.
Fig 1.
Type I secretion system (T1SS) clusters in X. arboricola strains.
Comparison of genomic regions encoding two T1SS clusters: (A) the hlyDB cluster and (B) the putative pctAB cluster (or an alternative novel T1SS). Genes corresponding to the secretion systems components and putative effectors are highlighted in blue, while some additional CDS are annotated as follows: Inc. Ca-binding prot. = Incomplete calcium-binding protein; Hyp. prot. = Hypothetical protein; IS3 ft = IS3 family transposase; Pyridoxal phosph.-dep. aminotransferase = Pyridoxal phosphate-dependent aminotransferase. Strains compared include Xap 2626 = IVIA 2626.1; Xap 33 = CITA 33; Xac 1846 = CFBP 1846; Xac 3978 = IVIA 3978; Xaj 1317 = IVIA 1317; Xaj 2499 = IVIA 2499.

Type III secretion system (hrp) cluster in X. arboricola strains.
Comparison of genomic regions encoding the T3SS components and accessory proteins. Genes corresponding to the hrp cluster are highlighted in blue, with one CDS annotated as Hyp. prot. = Hypothetical protein. Strains compared include Xap 2626 = IVIA 2626.1; Xap 33 = CITA 33; Xaj 1317 = IVIA 1317; Xaj 2499 = IVIA 2499; Xac 1846 = CFBP 1846; Xac 3978 = IVIA 3978.

Type III effectors (T3Es) in X. arboricola strains.
(A) Distribution of T3E repertoires identified in the bacterial strains analyzed. (B) Venn diagram showing the shared and unique repertoires of T3Es among the strains compared. Overlapping regions represent effectors common to two or more strains, while non-overlapping regions correspond to strain-specific T3Es. Strains compared include Xap 2626 = IVIA 2626.1; Xap 33 = CITA 33; Xaj 1317 = IVIA 1317; Xaj 2499 = IVIA 2499; Xac 1846 = CFBP 1846; Xac 3978 = IVIA 3978.
Fig 5.
Type V secretion system (T5SS) clusters in X. arboricola strains.
Comparison of genomic regions encoding different T5SS clusters: (A) estA homologs, (B) yapH homologs, (C) fhaB/fhaC homologs, (D) first and second xadA homologs, (E) third xadA homologs, and (F) fourth xadA homolog. Genes corresponding to the secretion system components are highlighted in blue, while some additional CDS are annotated as follows: IS5 ft = IS5 family transposase; Inc. hemagg. = Incomplete hemagglutinin repeat-containing protein; IS3 ft = IS3 family transposase; ISL3 ft = ISL3 family transposase; Hyp. prot. = Hypothetical protein; Hemagg. = Hemagglutinin repeat-containing protein. Strains compared include Xap 2626 = IVIA 2626.1; Xap 33 = CITA 33; Xaj 1317 = IVIA 1317; Xaj 2499 = IVIA 2499; Xac 1846 = CFBP 1846; Xac 3978 = IVIA 3978.
