    Genome-editing technologies using CRISPR–Cas nucleases have revolutionized plant science and hold enormous promise in crop improvement. Conventional transgene-mediated CRISPR–Cas reagent delivery methods may be associated with unanticipated genome changes or damage1,2, with prolonged breeding cycles involving foreign DNA segregation and with regulatory restrictions regarding transgenesis3.

    Conditional manipulation of gene expression is a key approach to investigating the primary function of a gene in a biological process. While conditional and cell-type-specific overexpression systems exist for plants, there are currently no systems available to disable a gene completely and conditionally. Here, we present a new tool with which target genes can efficiently and conditionally be knocked

    The calcium ion (Ca2+) is a universal signal in all eukaryotic cells. A fundamental question is how Ca2+, a simple cation, encodes complex information with high specificity. Extensive research has established a two-step process (encoding and decoding) that governs the specificity of Ca2+ signals. While the encoding mechanism entails a complex array of channels and transporters, the decoding process

    Because of intense transpiration and growth, the needs of plants for water can be immense. Yet water in the soil is most often heterogeneous if not scarce due to more and more frequent and intense drought episodes. The converse context, flooding, is often associated with marked oxygen deficiency and can also challenge the plant water status. Under our feet, roots achieve an incredible challenge to

    Nat. Plants (IF 13.256) Pub Date : 2020-05-01

    Disease is often said to be a great leveller, striking the rich and poor alike. However, the COVID-19 pandemic has thrown into stark contrast the inequalities inherent in our food systems.

  • The Nagoya Protocol and historical collections of plants.
    Nat. Plants (IF 13.256) Pub Date : 2020-05-01
    Brad Sherman,Robert James Henry

    Keeping pace with food demand and climate change requires continuous genetic improvement of crops that, in turn, relies on the availability of genetic resources. Access to these resources is complicated by the need to establish benefit-sharing arrangements when accessing and using such genetic resources.

  • Barebones of auxin signalling.
    Nat. Plants (IF 13.256) Pub Date : 2020-05-01
    C S Bascom,M Estelle

    Genetic redundancy is a problem when studying auxin in flowering plants. The minimal auxin response system in the liverwort Marchantia polymorpha allows a detailed and thorough probing of the specificity of auxin response factors in planta.

  • A molecular framework underlying the compound leaf pattern of Medicago truncatula.
    Nat. Plants (IF 13.256) Pub Date : 2020-05-11
    Liangliang He,Yu Liu,Hua He,Ye Liu,Jinfeng Qi,Xiaojia Zhang,Youhan Li,Yawen Mao,Shaoli Zhou,Xiaoling Zheng,Quanzi Bai,Baolin Zhao,Dongfa Wang,Jiangqi Wen,Kirankumar S Mysore,Million Tadege,Yongmei Xia,Jianghua Chen

    Compound leaves show more complex patterns than simple leaves, and this is mainly because of a specific morphogenetic process (leaflet initiation and arrangement) that occurs during their development. How the relevant morphogenetic activity is established and modulated to form a proper pattern of leaflets is a central question. Here we show that the trifoliate leaf pattern of the model leguminous plant

  • The lipid code-dependent phosphoswitch PDK1-D6PK activates PIN-mediated auxin efflux in Arabidopsis.
    Nat. Plants (IF 13.256) Pub Date : 2020-05-11
    Shutang Tan,Xixi Zhang,Wei Kong,Xiao-Li Yang,Gergely Molnár,Zuzana Vondráková,Roberta Filepová,Jan Petrášek,Jiří Friml,Hong-Wei Xue

    Directional intercellular transport of the phytohormone auxin mediated by PIN-FORMED (PIN) efflux carriers has essential roles in both coordinating patterning processes and integrating multiple external cues by rapidly redirecting auxin fluxes. PIN activity is therefore regulated by multiple internal and external cues, for which the underlying molecular mechanisms are not fully elucidated. Here, we

  • GOLVEN peptide signalling through RGI receptors and MPK6 restricts asymmetric cell division during lateral root initiation.
    Nat. Plants (IF 13.256) Pub Date : 2020-05-11
    Ana I Fernandez,Nick Vangheluwe,Ke Xu,Joris Jourquin,Lucas Alves Neubus Claus,Stefania Morales-Herrera,Boris Parizot,Hugues De Gernier,Qiaozhi Yu,Andrzej Drozdzecki,Takanori Maruta,Kurt Hoogewijs,Willem Vannecke,Brenda Peterson,Davy Opdenacker,Annemieke Madder,Zachary L Nimchuk,Eugenia Russinova,Tom Beeckman

    During lateral root initiation, lateral root founder cells undergo asymmetric cell divisions that generate daughter cells with different sizes and fates, a prerequisite for correct primordium organogenesis. An excess of the GLV6/RGF8 peptide disrupts these initial asymmetric cell divisions, resulting in more symmetric divisions and the failure to achieve lateral root organogenesis. Here, we show that

  • PDK1 regulates auxin transport and Arabidopsis vascular development through AGC1 kinase PAX.
    Nat. Plants (IF 13.256) Pub Date : 2020-05-11
    Yao Xiao,Remko Offringa

    The 3-phosphoinositide-dependent protein kinase 1 (PDK1) is a conserved master regulator of AGC kinases in eukaryotic organisms. pdk1 loss of function causes a lethal phenotype in animals and yeasts, but only mild phenotypic defects in Arabidopsis thaliana (Arabidopsis). The Arabidopsis genome contains two PDK1-encoding genes, PDK1 and PDK2. Here, we used clustered regularly interspaced short palindromic

  • Organizing principles for vegetation dynamics.
    Nat. Plants (IF 13.256) Pub Date : 2020-05-11
    Oskar Franklin,Sandy P Harrison,Roderick Dewar,Caroline E Farrior,Åke Brännström,Ulf Dieckmann,Stephan Pietsch,Daniel Falster,Wolfgang Cramer,Michel Loreau,Han Wang,Annikki Mäkelä,Karin T Rebel,Ehud Meron,Stanislaus J Schymanski,Elena Rovenskaya,Benjamin D Stocker,Sönke Zaehle,Stefano Manzoni,Marcel van Oijen,Ian J Wright,Philippe Ciais,Peter M van Bodegom,Josep Peñuelas,Florian Hofhansl,Cesar Terrer

    Plants and vegetation play a critical-but largely unpredictable-role in global environmental changes due to the multitude of contributing processes at widely different spatial and temporal scales. In this Perspective, we explore approaches to master this complexity and improve our ability to predict vegetation dynamics by explicitly taking account of principles that constrain plant and ecosystem behaviour:

  • Keeping leaves in shape.
    Nat. Plants (IF 13.256) Pub Date : 2020-05-01
    Ying Wang,Yuling Jiao

    Leaf development follows a common principle but is also flexibly tuned in different species in a spatiotemporal manner. A novel regulatory mechanism controlling leaflet formation has been identified in Medicago.
