BZR/BES transcription factors are widely recognized as mediators of brassinosteroid (BR)-responsive gene expression in seed plants, but details of how they act in species that lack BR perception are unclear. A study now uncovers an ancient mission of a BZR/BES transcription factor in sexual organ development in the liverwort Marchantia polymorpha.

A chromosome-level genome assembly for the amphibious plant Rorippa aquatica uncovers its tetraploid origin and an involvement of ethylene in heterophylly upon submergence.

The ‘non-canonical’ type-B BZR/BES transcription factor, MpBZR3, has been shown to be a regulator of the development of female and male reproductive organs in the model bryophyte Marchantia polymorpha.

This study reveals a pathway in which the transformation of trifoliate leaves into pinnate-like pentafoliate leaves is regulated by the conserved regulators of floral development (MtUFO) and leaf development (MtKNOXI) in M. truncatula.

Cell edges are part of a coordinate system used by the cell to direct three-dimensional growth in an organized manner. They emerge as signalling hubs with unique composition, capable of sensing mechanical stresses derived from neighbouring cells, to negotiate and harmonize individual cellular growth rates, therefore avoiding mechanical conflict.

A synthetic auxin improves the growth of adventitious roots in various plant species.
