KARRIKIN INSENSITIVE2-dependent signaling in the liverwort Marchantia polymorpha

Mizuno et al. show that genes in the KARRIKIN INSENSITIVE2-dependent signaling pathway are conserved in the liverwort Marchantia polymorpha and control early development of the thallus. Yohei Mizuno and Junko Kyozuka Background: Plants hormones play crucial roles in growth and development. Karrikins are smoke-derived germination signals, perceived by KARRIKIN INSENSITIVE2 (KAI2) in seed plants. An […]
