BREAKTHROUGH REPORTS
Leaf Variegation and Impaired Chloroplast Development Caused by a Truncated CCT Domain Gene in albostrians BarleyLeaf variegation in the barley mutant albostrians is caused by mutation of a single CCT–domain containing gene with residual activity, which is directed to the chloroplast.
OPENER Is a Nuclear Envelope and Mitochondria Localized Protein Required for Cell Cycle Progression in ArabidopsisThe evolutionarily conserved Arabidopsis protein OPENER localizes to the nuclear envelope and mitochondria and is required for cell cycle progression in developing seeds and seedling meristems.
LARGE-SCALE BIOLOGY ARTICLE
Breaking Free: The Genomics of Allopolyploidy-Facilitated Niche Expansion in White CloverAllopolyploid white clover arose in the last glaciation, retained progenitor genome integrity, and the few genes switching between homoeologues across tissues were enriched for flavonoid synthesis.
RESEARCH ARTICLES
Integration of Transcriptional Repression and Polycomb-Mediated Silencing of WUSCHEL in Floral MeristemsThe zinc-finger protein KNUCKLES integrates transcriptional repression with polycomb-mediated silencing of the floral stem cell determinant WUSCHEL.
Multiple Gibberellin Receptors Contribute to Phenotypic Stability under Changing EnvironmentsThe three tomato GID1 GA receptors exhibit redundancy under optimal growth conditions, but under changing environments, their overlapping functions contribute to phenotypic stability and robust growth.
The Transcription Factor INDUCER OF CBF EXPRESSION1 Interacts with ABSCISIC ACID INSENSITIVE5 and DELLA Proteins to Fine-Tune Abscisic Acid Signaling during Seed Germination in ArabidopsisA transcriptional complex involving ABSCISIC ACID INSENSITIVE5 and its interacting partners maintains the appropriate level of abscisic acid signaling during seed germination.
The Ca2+ Channel CNGC19 Regulates Arabidopsis Defense Against Spodoptera HerbivoryA cyclic nucleotide-gated, Ca2+ channel (CNGC19) is crucial for herbivory-induced Ca2+ influx, activation of downstream jasmonates, and aliphatic glucosinolate-mediated plant defense.
Paternally Acting Canonical RNA-Directed DNA Methylation Pathway Genes Sensitize Arabidopsis Endosperm to Paternal Genome DosageRNA-directed DNA methylation pathway genes act paternally to sensitize endosperm to excess paternal genomes, challenging previous models of dosage sensitivity in endosperm.
The SMC5/6 Complex Subunit NSE4A Is Involved in DNA Damage Repair and Seed DevelopmentCharacterization of the two NSE4 paralogs in Arabidopsis revealed that NSE4A is essential for both genome stability and plant reproduction.
Dual Role for Autophagy in Lipid Metabolism in ArabidopsisAutophagy regulates both lipid droplet biogenesis and turnover in plants.
Default Activation and Nuclear Translocation of the Plant Cellular Energy Sensor SnRK1 Regulate Metabolic Stress Responses and DevelopmentPlants appear to have modified the ancient and highly conserved eukaryotic energy sensor to better fit their unique lifestyle and more effectively cope with changing environmental conditions.
Molecular Basis of the Evolution of Methylthioalkylmalate Synthase and the Diversity of Methionine-Derived GlucosinolatesA combined plant genetic, biochemical, and structural biology study reveals the molecular basis for diversification of the agriculturally important Methionine-derived glucosinolates in plants.
Single-Organelle Quantification Reveals Stoichiometric and Structural Variability of Carboxysomes Dependent on the EnvironmentDetermination of absolute protein stoichiometry reveals the organizational variability of carboxysomes in response to microenvironmental changes.
