On the Cover

Aquatic plants have morphological adaptations and molecular responses to aquatic environments. In this issue, Yu et al. found that Iris pseudacorus could produce energy from glycolysis and fermentation at the initial stage of water flooding to maintain basic life activities. With the prolongation of waterlogging stress, the aerenchyma and adventitious roots of Iris pseudacorus were induced by IAA to form morphological adaptations.
