Zpl, a new gene in drosophila required for neurogenesis

Abstract

zpl(zip-like) gene mutant embryos showed the cuticular defect with alternative denticle rows and a hole from head to abdomen.zpl mutants also caused the overgrowth of neural cells and axons both in CNS and PNS as well as the wrong pathway of neural fasciculation and the disappearance of hypophysis,as shown by whole mount embryos stained with antibody against HRP and MAb-22C10.Genetic analysis has provided evidence that zpl,located in the right arm of the second chromosome(between 75 and 102 genetic map units),is a new gene closely related to the zip gene.
