Abstract

The tapetum, a tissue that elsewhere ensures correct spore development, is missing in some bryophytes. A new study shows that, in the liverwort, Marchantia polymorpha, a gene controlling spore wall deposition is expressed in the capsule lining, so these cells essentially function as a tapetum.
