Heterochrony in plant development

Abstract

Plants proceed through several distinct phases of growth and development in their life cycle. Under normal conditions, one phase terminates as another begins, but the relative time at which the phases initiate and terminate can be altered experimentally. New phenotypes are obtained when two developmental phases are expressed at the same time, as well as when phases are shifted coordinately. By analyzing these phenotypes, we can learn how plants normally regulate the transitions between developmental phases. © 1993 Academic Press. All rights reserved.
