Ten Years of the Maize Nested Association Mapping Population: Impact, Limitations, and Future DirectionsWith the recent release of genome assemblies for the NAM parents, we review the impact that the maize NAM population has had on the community and discuss its utility as we move into a new era of genomics.
BREAKTHROUGH REPORT
Identification of Plant Enhancers and Their Constituent Elements by STARR-seq in Tobacco LeavesA high-throughput assay in transiently transformed tobacco leaves identifies enhancers, characterizes their functional elements and detects condition-specific enhancer activity.
The EccDNA Replicon: A Heritable, Extranuclear Vehicle That Enables Gene Amplification and Glyphosate Resistance in Amaranthus palmeriThe eccDNA replicon is a large extranuclear circular DNA that is composed of a sophisticated repetitive structure and harbors the EPSPS and several other genes that are transcribed during glyphosate stress.
Endosidin20 Targets the Cellulose Synthase Catalytic Domain to Inhibit Cellulose BiosynthesisThe cellulose synthase inhibitor Endosidin20 is an excellent tool for manipulating cellulose synthesis in order to produce cellulose products with desired properties and to control weeds.

Convergent Loss of an EDS1/PAD4 Signaling Pathway in Several Plant Lineages Reveals Coevolved Components of Plant Immunity and Drought ResponseGenome analyses reveal that several plants have lost a major part of the immune system.
RESEARCH ARTICLES
Dual Recognition of H3K4me3 and DNA by the ISWI Component ARID5 Regulates the Floral Transition in ArabidopsisDual recognition of H3K4me3 and DNA by the CRA-type ISWI complex subunit ARID5 is required for gene expression, development, and the floral transition.
MYB30 Is a Key Negative Regulator of Arabidopsis Photomorphogenic Development That Promotes PIF4 and PIF5 Protein Accumulation in the LightThe MYB transcription factor MYB30 negatively regulates photomorphogenesis and promotes PIF4 and PIF5 protein accumulation under prolonged red light irradiation.
STRESS INDUCED FACTOR 2 Regulates Arabidopsis Stomatal Immunity through Phosphorylation of the Anion Channel SLAC1SIF2 is critical for Arabidopsis (Arabidopsis thaliana) resistance to bacteria by regulating stomatal immunity, belongs to the FLS2/BAK1 immunity receptor complex, and phosphorylates the anion channel SLAC1.
PLANT NATRIURETIC PEPTIDE A and Its Putative Receptor PNP-R2 Antagonize Salicylic Acid–Mediated Signaling and Cell DeathIntercellular signaling mediated by PNP-A and its putative receptor protein PNP-R2 counteracts SA-mediated plant stress responses.
Strigolactone and Karrikin Signaling Pathways Elicit Ubiquitination and Proteolysis of SMXL2 to Regulate Hypocotyl Elongation in ArabidopsisStrigolactone and karrikin signaling pathways trigger polyubiquitination and degradation of SMXL2 to regulate hypocotyl elongation and gene expression in Arabidopsis.
The Type-B Cytokinin Response Regulator ARR1 Inhibits Shoot Regeneration in an ARR12-Dependent Manner in ArabidopsisARR1, a type-B ARR, is defined as an important inhibitor of in vitro shoot regeneration that modulates the expression of WUS and CLV3 in an ARR12-dependent manner, and directly activates IAA17.
ARGONAUTE2 Enhances Grain Length and Salt Tolerance by Activating BIG GRAIN3 to Modulate Cytokinin Distribution in RiceOptimizing cytokinin distribution patterns is a promising strategy for simultaneously enhancing grain yield, grain quality, and stress resistance in plants, as observed in ARGONAUTE2-overexpressing rice.
WRKY15 Suppresses Tracheary Element Differentiation Upstream of VND7 During Xylem FormationArabidopsis WRKY15 functions upstream of VND7, an important regulator of tracheary element (TE) differentiation, to suppress TE formation during plant vascular development.
Guard Cell Starch Degradation Yields Glucose for Rapid Stomatal Opening in ArabidopsisFast stomatal opening kinetics in response to light in Arabidopsis depends on a tight coordination between membrane ion transport and metabolic rearrangements.
A Natural Variation in PLEIOTROPIC DEVELOPMENTAL DEFECTS Uncovers a Crucial Role for Chloroplast tRNA Modification in Translation and Plant DevelopmentChloroplast tRNA modification influences protein translation, leading to pleiotropic developmental defects in rice, as revealed by analysis of a natural allele of tRNA-modifying GTPase gene PDD.
Molecular Mechanism of Polysaccharide Acetylation by the Arabidopsis Xylan O-acetyltransferase XOAT1Structural and biochemical analysis of xylan O-acetyltransferase 1 (XOAT1) show that XOAT1 catalyzes xylan acetylation through formation of an acyl-enzyme intermediate via a double displacement bi-bi mechanism.
Cellular Plasticity in Response to Suppression of Storage Proteins in the Brassica napus EmbryoSuppressing the genes encoding napin and cruciferin leads to an increase in oleosin accumulation and a reorganization of the intracellular architecture in the developing embryo of oilseed rape.
Molecular Basis for a Cell Fate Switch in Response to Impaired Ribosome Biogenesis in the Arabidopsis Root EpidermisRibosome biogenesis defects and stress conditions trigger a transcriptional regulatory pathway that causes a cell fate switch in the root epidermis.
TRIPP Is a Plant-Specific Component of the Arabidopsis TRAPPII Membrane Trafficking Complex with Important Roles in Plant DevelopmentA proteomic study sheds light on Transport Protein Particle (TRAPP) proteins in plants and identifies TRIPP as a plant-specific component of the TRAPPII complex with important roles in vesicle trafficking and plant development.
