Perspectives

Filter By:

Article Type
  • 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
    Perspective
  • 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
    Perspective
  • 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.

    • Alice Malivert
    • Olivier Hamant
    Perspective
  • 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
    Perspective
  • 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
    Perspective
  • 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
    Perspective
  • 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.

    • Fausto Andres Ortiz-Morea
    • Jun Liu
    • Ping He
    Perspective
  • 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.

    • Jingfeng Xiao
    • Joshua B. Fisher
    • Nicholas C. Parazoo
    Perspective
  • 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.

    • Teva Vernoux
    • Fabrice Besnard
    • Christophe Godin
    Perspective
  • 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.

    • Evan M. Gora
    • Adriane Esquivel-Muelbert
    Perspective
  • 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.

    • Peter Horton
    • Stephen P. Long
    • David J. Beerling
    Perspective
  • 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.

    • Kadambot H. M. Siddique
    • Xuan Li
    • Karl Gruber
    Perspective
  • All living organisms require proper environmental pH for normal growth and development. Unlike in bacteria, fungi and animal cells, the mechanisms for environmental pH sensing in plants are underexamined. In this Perspective, the authors summarize the current understanding of the process in various organisms and propose possible molecular mechanisms underlying the perception of external pH in plants.

    • Huei-Hsuan Tsai
    • Wolfgang Schmidt
    Perspective
  • The landscape of forest and human activity is ever shifting, but new large-scale trends are causing exceptional changes and potential space for new conservation and development for communities dependent on forests.

    • Johan A. Oldekop
    • Laura Vang Rasmussen
    • Sarah J. Wilson
    Perspective
  • This perspective highlights the new species-independent analytical tools with a focus on plant nanosensors and portable Raman spectroscopy, and evaluates their applications in agriculture, such as detecting plant stresses and monitoring crop physiology.
