Hox Interactions mediate collinearity and TST. Above: the sequence of genes in the whole Xenopus A-P axis: Starting anteriorly with the EAD gene XAG1, going on to head genes and finishing, posteriorly, with Hox pralogue groups 1–13. Next down: Hox1 LOF: The whole posterior axis, including Hox1 is deleted or compromised. Gbx2 is upregulated (not shown) Next down: Hoxc6 LOF: The posterior axis from and including Hox6 is deleted. Hoxc4 and Hoxc5 are upregulated (not shown) Next: Hoxb9 GOF in a noggin embryo. A partial axis is generated, starting at Hox9 [5,26,28].
