Plasticity in mRNA expression and localization of orthodenticle within higher Diptera.

abstract：:When approaching the study of terminal growth and segmentation, comparative morphology provides an important guide to formulate questions. There are often problems in unambiguously identifying the axis along which we wish to study terminal (often, actually, subterminal) growth, especially when the trunk axis is poster...
