—An integron-like mechanism may be responsible for the reassortment of TALE genes. (A) Organization of gene clusters formed by integrons, including the hairpin structures at attC sites, adapted from Nivina et al. (2016). (B) Schematic arrangement of TALE genes in clusters with short spacer regions in Xoc. Putative hairpin structures may be found at the C-terminal region of TALE genes (grey) as well as in the spacer regions (green/blue). Colors chosen in analogy to supplementary fig. 13, Supplementary Material online. (C) Secondary structure of the C-terminal hairpin as predicted by Mfold. (D) Secondary structure of the hairpin in the spacer region.
