Mum versus Dad: Parent–offspring conflict in mosses
Non-flowering plants have rather complex reproductive life cycles compared to the more familiar pattern of fertilization and seed formation seen in Angiosperms.
Is the moss calyptra covered by a cuticle?
Over a century ago, the gametophytic calyptra was predicted to be covered by a cuticle that protects the sporophyte apex from desiccation. Budke et al. examine the moss Funaria hygrometrica using electron microscopy...
