Two Reviews: CRISPR/Cas for genome engineering in plants, and Genome editing in cereal crops ($) The gene-editing technology CRISPR/Cas, which introduces double-strand breaks that are repaired by non-homologous end joining (NHEJ), is best known for the promise it holds in modifying an organism’s DNA sequence without the introduction of exogenous genes. However, as Puchta describes … Read more
IN BRIEF by Jennifer Lockhart jlockhart@aspb.org DNA is sculpted by several types of epigenetic modifications with profound effects on gene expression, development, and stress responses. Much less is known about the more than 100 chemical modifications shaping plant RNA, a topic explored in the newly emerging field of epitranscriptomics (reviewed in Burgess et al., 2016). … Read more
Editorial: Rigorous Science: a How-To Guide Casadevall and Fang set out several proposals for research training to help ensure scientific “rigor”, which they define as promoting confidence in the truth or accuracy of the findings. The authors propose and elaborate on five foundations for scientific rigor: Redundancy in experimental design, recognition of error, intellectual honesty, … Read more
Review: Transport and homeostasis of K and P ($) Nitrogen (N), phosphorus (P), and potassium (K) are the three macronutrients required in highest amounts for plant growth. N is abundant in the atmosphere, therefore plentiful if we overlook the energetic costs of converting N2 to usable form. By contrast, K and P are present in … Read more

Jaewook Kim, Kijong Song, and Eunae Park, featured authors of Epidermal Phytochrome B Inhibits Hypocotyl Negative Gravitropism Non-Cell Autonomously Jaewook Kim Current Position: Graduate student, … Read more
Featured Review: Programmed Cell Death in Development and Disease Programmed cell death (PCD) is an active process that occurs as part of normal development and also contributes to defense against pathogens. While there are many similarities in developmental PCD (dPCD) and pathogen-triggered PCD (pPCD), there are also differences. Huysmans et al. review and contrast these … Read more
Featured Review: The Broad Footprint of Climate Change From Genes to Biomes to People ($) In this review, Scheffers et al. collate a vast amount of data to summarize the impact of climate change on terrestrial, freshwater and marine ecosystems; their findings are sobering. A key conclusion is that across the 94 processes analyzed, 84% … Read more
Featured Review: Effects of water stress on rhizodeposition Rhizodeposition refers to the release of organic compounds from roots into soil. Rhizodeposits alter the composition and structure of soil and also provide food for soil microbes whose actions can increase the bioavailability of soil organic matter. Preece and Peñuelas review how drought affects rhizodeposition, which in … Read more
We start with a trio of papers that explore plant cell proliferation Featured Review: Plants grow with a little help from their organelle friends ($) Mitochondria and chloroplasts are semi-autonomous organelles that provide cells with energy, metabolites and hormones. Van Dingenen et al. review organelles’ dynamic roles during organ growth. As an obvious example, many … Read more
Featured Review: Role of Mass Spectrometry in Biology Mass spectrometry (MS) has become a core tool for molecular and structural biology. Lössl et al. review the history of MS and provide an accessible explanation for how it works and its applications, with numerous examples. This is a must-read for students of biochemistry as well as … Read more
Recently, we’ve been profiling first authors of Plant Cell papers that are selected for In Brief summaries. Here are the first-author profiles from the October issue of The Plant Cell. Olivia Wilkins and Christoph Hafemeister, featured first authors of EGRINs (Environmental Gene Regulatory Influence Networks) in Rice That Function in the Response to Water Deficit, … Read more
Featured Review: Evolution of ROS signaling ($) Reactive oxygen species (ROS) are partially reduced or excited forms of oxygen (for example, O2·−) that are reactive and damaging towards cellular components. Because ROS are produced as byproducts of metabolism, cells have evolved ROS detoxification pathways; more than 150 Arabidopsis genes contribute to ROS detoxification. Inupakutika et … Read more
Featured Review: Update of Arabidopsis floral meristem formation ($) Genetic approaches using Arabidopsis have identified key players in the initiation and elaboration of floral meristems and flowers. These core findings are now expanded to encompass the roles of hormone fluxes and mechanical forces, and systems-wide modeling of gene regulatory networks. In this review, Denay et … Read more
Featured Review: Celebrating 150 years since Mendel’s Discoveries ($) This review describes Mendel’s seminal work and how it laid the foundation for today’s plant breeding (as well as all of genetics).
