Gravity-dependent reactions of the moss Pohlia nutans protonemata

In darkness, protonemata of Pohlia nutans (Hedw.) grew negatively gravitropically (upwards). However, not all filaments became gravitropic immediately after transfer to darkness. Some of them (∼20%) for several days grew in different directions with respect to gravity. The apical cells of those prot...
