  • The authors present the design principles of a synthetic earthmoss (Physcomitrium patens) genome. To aid future genome design projects, they also develop GenoDesigner, a software package that provides users with an intuitive graphical interface to efficiently manipulate genomic sequences.

  • In this Perspective, Vincent Merckx and colleagues discuss an important but overlooked aspect of mycorrhizal interactions, mycoheterotrophy, in the context of recent arguments about the importance of these interactions to forest functioning.

    • Vincent S. F. T. Merckx
    • Sofia I. F. Gomes
    • Martin I. Bidartondo
  • In this Perspective, Mascher et al. look back on 30 years of genetic and genomic research in cereal crops. Genome sequences have revealed common evolutionary patterns as well as differences between species and will support applications in breeding.

    • Marina Püpke Marone
    • Nils Stein
  • In this Perspective, Finger and Möhring discuss the emergence of pesticide-free crop production systems in Europe in the context of real-world examples and highlight the barriers to adoption of this cropping strategy.

    • Robert Finger
    • Niklas Möhring
  • This Perspective presents an historical overview and recent advances on adenylate cyclases (ACs) and cAMP signalling in plants, including an exploration of the active AC functions moonlighting within multifunctional protein complexes.

    • Aloysius Wong
    • Wei Chi
    • Chris Gehring
  • The authors revisit the array of phenotypes linked to FERONIA in an attempt to identify a unifying feature behind its many biological and biochemical functions. They propose that the contribution of FERONIA to monitoring turgor-dependent cell wall tension may explain its pleiotropy.

    • Olivier Hamant
  • Plants often need to bend their organs during their growth and development. It is a complex process, and the different mechanisms involved are discussed in the light of recent findings about genes, signalling, modelling and biomechanics.

    • Kristoffer Jonsson
    • Yuan Ma
    • Rishikesh P. Bhalerao
  • This Perspective reviews recent advances in crop transformation technologies that promise to lead to the widespread adoption of genome editing in crop species.

    • Zongliang Chen
    • Juan M. Debernardi
    • Andrea Gallavotti
  • CLE peptides control stem-cell activity in meristems. Recent studies in Marchantia and Arabidopsis support the idea that an ancestral function of CLE peptides was to promote stem cells. After gene duplication in angiosperms, a subset of CLE peptides became stem-cell suppressors.

    • Yuki Hirakawa
  • Plant malectin-like receptor kinases (also known as CrRLK1Ls) have functions in plant development such as pollen tube growth and cell wall integrity sensing. This Perspective reviews recent evidence suggesting a critical role of these receptors in plant immunity.

  • While diurnal cycling of carbon and water use are critical for plant and ecosystem research, existing polar-orbiting satellites are incapable of providing such measurements. This Perspective evaluates the potential contributions of new satellites and platforms for Earth system models.

    • Joshua B. Fisher
    • Nicholas C. Parazoo
  • How do plants acquire their shape? In this Perspective, the authors discuss how morphogenesis and patterning occur in the Arabidopsis shoot apical meristem, and the benefits of computational modelling to understand this complex process.

    • Fabrice Besnard
    • Christophe Godin
  • Increases in tree mortality affect the ability of forests to absorb and store atmospheric carbon, but how the largest trees die is still relatively understudied. This Perspective posits and examines several biotic and abiotic drivers affecting these trees and their disproportionate impacts.

    • Adriane Esquivel-Muelbert
  • Agriculture attempts to satisfy the demand for food of a growing human population but contributes to environmental degradation. However, there are technological options for agriculture to deliver food security and potentially reduce atmospheric CO2.

  • Asia has a rich variety of nutritious ‘neglected crops’, including cereals, roots and pulses. Adopting a diverse cropping portfolio using these forgotten crops is a promising approach to closing the current production and nutrition gaps.
