PERSPECTIVE
Reassess the t Test: Interact with All Your Data via ANOVAA perspective on how moving away from pairwise t tests towards general linear modelling such as ANOVA will help the plant biology community.
REVIEW
The Plant Peptidome: An Expanding Repertoire of Structural Features and Biological FunctionsA unifying peptide classification system is proposed, reflecting the huge diversity of plant peptides.
LARGE-SCALE BIOLOGY ARTICLES
Conserved Gene Expression Programs in Developing Roots from Diverse PlantsGene expression maps from the roots of seven plant species show a surprising degree of conservation in the genes and expression patterns employed during root development.
Characteristics of Plant Essential Genes Allow for within- and between-Species Prediction of Lethal Mutant PhenotypesEssential genes in Arabidopsis thaliana display distinct characteristics that are used to build machine learning models capable of predicting lethal-phenotype genes within and between species.
Comprehensive Annotation of Physcomitrella patens Small RNA Loci Reveals That the Heterochromatic Short Interfering RNA Pathway Is Largely Conserved in Land PlantsThe moss Physcomitrella patens has over 1000 small RNA loci that produce 23- to 24-nucleotide heterochromatic short interfering RNAs, some of which are dependent upon a minimal Dicer-Like gene.
RESEARCH ARTICLES
Novel DICER-LIKE1 siRNAs Bypass the Requirement for DICER-LIKE4 in Maize DevelopmentA DCL1-dependent siRNA pathway bypasses the requirement for DCL4 in development, which can reduce selective constraints on DCL4, allowing it to diversify in response to viral suppressors.
Small RNA Derived from the Virulence Modulating Region of the Potato spindle tuber viroid Silences callose synthase Genes of Tomato PlantsSmall RNA derived from the virulence modulating region of the Potato spindle tuber viroid downregulates callose synthase by RNA silencing in tomato.
Manipulation of Guaiacyl and Syringyl Monomer Biosynthesis in an Arabidopsis Cinnamyl Alcohol Dehydrogenase Mutant Results in Atypical Lignin Biosynthesis and Modified Cell Wall StructureThe phenotypes of Arabidopsis plants with altered aldehyde contents and guaiacyl-to-syringyl ratios provide insights into the effects of lignin composition on plant growth and cell wall degradability.
Flavonoids and Auxin Transport Inhibitors Rescue Symbiotic Nodulation in the Medicago truncatula Cytokinin Perception Mutant cre1The inability of the cytokinin perception mutant cre1 to form symbiotic nodules in Medicago truncatula was linked to a deficiency in auxin transport regulation mediated by endogenous flavonoids.
Quantitative Variation in Responses to Root Spatial Constraint within Arabidopsis thalianaRosette growth in Arabidopsis is sensitive to the placement of a small physical constraint around the root and this requires a number of naturally variable loci.
Crosstalk between Two bZIP Signaling Pathways Orchestrates Salt-Induced Metabolic Reprogramming in Arabidopsis RootsA signaling module in Arabidopsis roots, consisting of SnRK1 kinases and bZIP1 transcription factors, reprograms metabolism to enable plants to adapt to salt stress conditions.
Brassinosteroids Are Master Regulators of Gibberellin Biosynthesis in ArabidopsisIn Arabidopsis thaliana, brassinosteroids regulate the biosynthesis of gibberellins and thereby regulate plant growth and development.
A Repressor Protein Complex Regulates Leaf Growth in ArabidopsisPPD2 interacts with KIX8 and KIX9 proteins to regulate the transcription of its target genes, including the CYCD3s, and helps to control final leaf size in Arabidopsis.
Conserved Functions of the MATE Transporter BIG EMBRYO1 in Regulation of Lateral Organ Size and Initiation RateBig embryo 1 encodes a trans-Golgi localized MATE transporter required for regulation of lateral organ size and initiation rate in plants.
The Transcriptional Coregulator LEUNIG_HOMOLOG Inhibits Light-Dependent Seed Germination in ArabidopsisLEUNIG_HOMOLOG interacts with the transcription factor PHYTOCHROME-INTERACTING FACTOR1 and acts as a transcriptional coregulator to inhibit light-dependent seed germination in Arabidopsis.
