    Trends Plant Sci. (IF 14.416) Pub Date : 2020-06-05
    Marek Marzec,Goetz Hensel

    Prime editing, developed by Anzalone et al., brings genome editing to a new level, because this approach allows introduction of all mutation types, including insertions, deletions, and all putative 12 types of base-to-base conversions. Previously tested in human cells, this technique has been adapted for use in plants by Lin et al.

  • Pectin Drives Cell Wall Morphogenesis without Turgor Pressure.
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-06-05
    Dangquan Zhang,Baohong Zhang

    How the plant cell wall expands and forms shapes is a long-standing mystery. Traditional thought is that turgor pressure drives these processes. However, a recent study by Haas and colleagues shows for the first time that the expansion of pectin homogalacturonan nanofilaments drives morphogenesis without turgor pressure in plant epidermal cells.

  • Pericyclic versus Endodermal Lateral Roots: Which Came First?
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-06-03
    Steffen Vanneste,Tom Beeckman

    Digging into the limited literature on lateral root (LR) formation in early vascular plants, we came to the novel conclusion that the pericycle, rather than the endodermis as commonly assumed, represents the ancestral tissue that was evolutionarily recruited to form LRs.

  • Transgenic Poplar Designed for Biofuels.
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-05-29
    Nathan D Bryant,Yunqiao Pu,Timothy J Tschaplinski,Gerald A Tuskan,Wellington Muchero,Udaya C Kalluri,Chang Geun Yoo,Arthur J Ragauskas

    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. To this effect, there have been efforts to modify gene expression to

    Nipuni Thanthrige,Sachin Jain,Sudipta Das Bhowmik,Brett J Ferguson,Mehdi Kabbage,Sagadevan Mundree,Brett Williams

    Programmed cell death (PCD) is a genetically regulated process for the selective demise of unwanted and damaged cells. Although our understanding of plant PCD pathways has advanced significantly, doubts remain on the extent of conservation of animal apoptosis in plants. At least at the primary sequence level, plants do not encode the regulators of animal apoptosis. Structural analyses have enabled

  • Does Gene Expression Noise Play a Functional Role in Plants?
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-05-25
    Sandra Cortijo,James C W Locke

    Gene expression in individual cells can be surprisingly noisy. In unicellular organisms this noise can be functional; for example, by allowing a subfraction of the population to prepare for environmental stress. The role of gene expression noise in multicellular organisms has, however, remained unclear. In this review, we discuss how new techniques are revealing an unexpected level of variability in

  • Crop Halophytism: An Environmentally Sustainable Solution for Global Food Security.

    Ting Li,Nathalie Gonzalez,Dirk Inzé,Marieke Dubois

    Small RNAs (sRNAs), mainly including miRNAs and siRNAs, are ubiquitous in eukaryotes. sRNAs mostly negatively regulate gene expression via (post-)transcriptional gene silencing through DNA methylation, mRNA cleavage, or translation inhibition. The mechanisms of sRNA biogenesis and function in diverse biological processes, as well as the interactions between sRNAs and environmental factors, like (a)biotic

  • Soil Rather Than Xylem Vulnerability Controls Stomatal Response to Drought.
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-05-03
    Andrea Carminati,Mathieu Javaux

    The current trend towards linking stomata regulation to plant hydraulics emphasizes the role of xylem vulnerability. Using a soil-plant hydraulic model, we show that xylem vulnerability does not trigger stomatal closure in medium-wet to dry soils and we propose that soil hydraulic conductivity loss is the primary driver of stomatal closure. This finding has two key implications: transpiration response

    Hongwei Liu,Laura E Brettell,Zhiguang Qiu,Brajesh K Singh

    Plants are subjected to diverse biotic and abiotic stresses in life. These can induce changes in transcriptomics and metabolomics, resulting in changes to root and leaf exudates and, in turn, altering the plant-associated microbial community. Emerging evidence demonstrates that changes, especially the increased abundance of commensal microbes following stresses, can be beneficial for plant survival

  • Autophagosome Biogenesis in Plants: An Actin Cytoskeleton Perspective.
    Trends Plant Sci. (IF 14.416) Pub Date : 2020-04-25
    Pengwei Wang,Erlin Gao,Patrick J Hussey

    At the subcellular level, the cytoskeleton regulates cell structure, organelle movement, and cytoplasmic streaming. Autophagy is a process to remove unwanted biomaterials or damaged organelles through double membrane compartments known as autophagosomes. Autophagosome biogenesis requires vesicle trafficking between donor and acceptor compartments, membrane expansion, and fusion, which is very likely

    Trends Plant Sci. (IF 14.416) Pub Date : 2020-03-19
    Ren-Jie Tang,Chao Wang,Kunlun Li,Sheng Luan

    Calcium (Ca2+) serves as an essential nutrient as well as a signaling agent in all eukaryotes. In plants, calcineurin B-like proteins (CBLs) are a unique group of Ca2+ sensors that decode Ca2+ signals by activating a family of plant-specific protein kinases known as CBL-interacting protein kinases (CIPKs). Interactions between CBLs and CIPKs constitute a signaling network that enables information integration

    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

    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.

    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

    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
