  • Gibberellin is an important plant hormone that regulates several development processes. This paper presents a ternary complex of gibberellin bound to its receptor and a fragment of a DELLA protein. The structures reveal the mechanistic basis of gibberellin recognition, which is distinct from auxin perception.

  • Self-incompatibility responses in Brassica are induced by haplotype-specific interactions between the pistil-expressed SRK receptor and pollen-expressed SP11 ligand. Here, via crystal structures and molecular dynamic simulations, the authors provide a model to explain why binding of cognate partners is favoured and how haplotypes can be distinguished.

  • The phenotypic expression of SP11 alleles ­— male determinants of self-incompatibility in Brassica rapa ­— is controlled by a five-phased linear hierarchy. A study has found that a polymorphic 24-nt small RNA controls the linear hierarchy of four of the SP11 alleles.

  • The two GRAS transcription factors SHR and SCR play a role in root development by interacting with proteins of the BIRD/IDD family, such as JACKDAW. Structural and biochemical characterization of the three components explains how the subunits interact together and with DNA.

  • Designer supramolecular polymers are a growing field of polymer materials. The designability and flexibility in their structures and functionality have attracted a great deal of attention in polymer science, as well as in supramolecular chemistry. These polymeric structures are formed from one or more molecular components via reversible bonds; therefore, monomeric and polymeric states are in equilibrium on the relevant experimental timescale. The dynamic nature of supramolecular polymers in terms of chain lifetime and conformational flexibility are determined by external conditions. This adaptivity can result in stimuli-responsive structures and properties. This article describes the use of our host–guest structures based on a calix[5]arene, a bisporphyrin, and a self-assembled capsule in the synthesis of supramolecular polymers.
