Fig. 4 Heterochrony between Xenopus and Drosophila and plan of the experiment. The figure shows relative stages for ectopic hox expression, mRNA harvesting and gastrulation in Xenopus and Drosophila. Gb and Ge: beginning and end of gastrulation. Ho1, Ho6: the times when Hox1 and Hox6 expression start. Nb, Ne: the beginning and end of ectopic expression under the nullo promoter in Drosophila. Ha: time point for harvesting total mRNA. mRNA: injection of Xlhoxc6 mRNA into Xenopus. T = 0: start of development: zygote stage. The figure shows that the relationship between Hox expression and gastrulation is different in Xenopus (where Hox expression begins during gastrualtion) and Drosophila (where Hox expression begins before gastrulation). The latest time point for harvesting Drosophila mRNA (16 h: end of embryogenesis) is not shown (it is far right, off the figure). Image published in: Michaut L et al. (2011) Copyright © 2011.
