Action of theTunicatelocus on maize floral development

摘要

AbstractThe co‐dominantTunicate(Tu) mutation in maize causes nonreproductive structures in both the male and female inflorescences to be enlarged. This mutation also affects sex determination, permitting the development of pistils in the normally staminate tassel. In order to characterize the role of the normaltugene product, we have analysed genetic interaction betweenTuand other mutations that perturb specific stages of floral development. Synergistic interactions observed suggested that thetuproduct functions in at least three stages of floral development–determination of spikelet primordia, differentiation of non‐reproductive organs and pistil abortion in the tassel. © 1994 Wiley‐L
