... at tailbud stage. Recent studies have identified several important components of the molecular pathways controlling posterior neurogenesis, but little is known about those controlling the timing and positioning of anterior neurogenesis. We investigate the role of Xrx1 , a homeobox gene required for eye...

... of the bicoid -class homeobox gene Xotx2 but very soon, at the beginning of neurulation, it becomes devoid of Xotx2 transcripts in spatiotemporal concomitance with the transcriptional activation of the paired -like homeobox gene Xrx1 . By use of gain-and loss-of-function approaches, we have studied the role...
