  • Do Cell Wall Esters Facilitate Forest Response to Climate?
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-06-26
    Rebecca A. Dewhirst; Jenny C. Mortimer; Kolby J. Jardine

    Terrestrial ecosystem dynamics are strongly modified by stresses associated with climate change, impacting plant growth and development, mortality, and ecological succession. Here we highlight the potential role of plant cell wall esters to link changes in cell wall structure and function with biosphere–atmosphere fluxes of methanol, acetic acid, carbon dioxide (CO2), and water (H2O).

    Establishing laws of plant and ecosystems functioning has been an overarching objective of functional and evolutionary ecology. However, most theories neglect the role of human activities in creating novel ecosystems characterized by species assemblages and environmental factors that are not observed in natural systems. We argue that agricultural weeds, as an emblematic case of such an ‘ecological

    The phyllosphere harbors diverse microbial communities that influence ecosystem functioning. Emerging evidence suggests that plants impaired in genetic networks harbor an altered microbiome and develop dysbiosis in the phyllosphere, which pinpoints plant genetics as a key driver of the phyllosphere microbiome assembly and links the phyllosphere microbiome to plant health.

    Members of the genus Populus (i.e., cottonwood, hybrid poplar) represent a promising source of lignocellulosic biomass for biofuels. However, one of the major factors negatively affecting poplar’s efficient conversion to biofuel is the inherent recalcitrance to enzymatic saccharification due to cell wall components such as lignin.

  • Fine-Tuning Immunity: Players and Regulators for Plant NLRs.
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-03-17
    Yang Sun,Yu-Xiu Zhu,Peter J Balint-Kurti,Guan-Feng Wang

    Plants have evolved a sophisticated innate immune system to defend against pathogen infection, and intracellular nucleotide-binding, leucine-rich repeat (NLR or NB-LRR) immune receptors are one of the main components of this system. NLR activity is fine-tuned by intra- and intermolecular interactions. We survey what is known about the conservation and diversity of NLR-interacting proteins, and divide

  • Does the GABA Shunt Regulate Cytosolic GABA?
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-03-16
    Alan W Bown,Barry J Shelp

    The GABA shunt has long been known as a metabolic pathway that produces GABA in, and removes GABA from, the cytosol. There is no consensus regarding its function. The hypothesis presented here is that the GABA shunt regulates cytosolic GABA levels and GABA signaling.

  • Aromatic Amino Acids: A Complex Network Ripe for Future Exploration.
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-03-13
    Joseph H Lynch,Natalia Dudareva

    In plants, high carbon flux is committed to the biosynthesis of phenylalanine, tyrosine, and tryptophan, owing to their roles not only in the production of proteins, but also as precursors to thousands of primary and specialized metabolites. The core plastidial pathways that supply the majority of aromatic amino acids (AAAs) have previously been described in detail. More recently, the discovery of

  • Delivering Integrated Pest and Pollinator Management (IPPM).
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-03-12
    Paul A Egan,Lynn V Dicks,Heikki M T Hokkanen,Johan A Stenberg

    The need to reduce pollinator exposure to harmful pesticides has led to calls to expedite the adoption of integrated pest management (IPM). We make the case that IPM is not explicitly 'pollinator friendly', but rather must be adapted to reduce impacts on pollinators and to facilitate synergies between crop pollination and pest control practices and ecosystem services. To reconcile these diverse needs

  • The Hidden Costs of Nighttime Warming on Yields.
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-03-10
    Walid Sadok,S V Krishna Jagadish

    Nighttime warming poses a threat to global food security as it is driving yield declines worldwide, but our understanding of the physiological basis of this phenomenon remains very limited. Furthermore, it is often assumed that such declines are driven solely by increases in nighttime temperature (TNight). Here we argue that, in addition to temperature, increases in nighttime evaporative demand may

  • Towards Engineering Broad-Spectrum Disease-Resistant Crops.
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-03-10
    Jingjing Tian,Guoyong Xu,Meng Yuan

    Crop pathologists and breeders are pursuing not only mechanistic understanding of plant-pathogen interactions but also engineering durable and broad-spectrum disease-resistant cultivars. Both goals are achieved in three recent studies by stacking editing of regulatory elements within promoters of susceptibility genes for blight disease in rice.

  • Achieving Plant Genome Editing While Bypassing Tissue Culture.
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-03-10
    Xiang Ji,Bing Yang,Daowen Wang

    Conventional genetic transformation is a huge obstacle to the efficient development and application of plant genome-editing (GE) technologies. Recently, Maher et al. reported successful GE by de novo reprogramming plant meristems in somatic tissues, which sidesteps tissue culture-based transformation and promises to significantly enhance the utility of plant GE.

  • A State Factor Model for Ecosystem Carbon-Water Relations.
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-03-09
    Toby M Maxwell,Lucas C R Silva

    With increasing calls for improving terrestrial carbon sequestration and sustainable water use, scientists are faced with the challenge of predicting changes in carbon–water relations from organisms to landscapes. We propose an integrative framework to help in answering basic and applied questions pertaining to coupled carbon–water functions in a variety of ecosystems. The conceptual framework is based

  • Roadmap for Accelerated Domestication of an Emerging Perennial Grain Crop.
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-03-05
    Lee DeHaan,Steve Larson,Rosa L López-Marqués,Stephan Wenkel,Caixia Gao,Michael Palmgren

    Shifting the life cycle of grain crops from annual to perennial would usher in a new era of agriculture that is more environmentally friendly, resilient to climate change, and capable of soil carbon sequestration. Despite decades of work, transforming the annual grain crop wheat (Triticum aestivum) into a perennial has yet to be realized. Direct domestication of wild perennial grass relatives of wheat
