LARGE-SCALE BIOLOGY ARTICLES
Gene Duplicability of Core Genes Is Highly Consistent across All AngiospermsLarge-scale analysis of a set of core gene families shows that gene duplicability is surprisingly similar across 37 angiosperm genomes and independent whole-genome duplication events.
Time-Series Transcriptomics Reveals That AGAMOUS-LIKE22 Affects Primary Metabolism and Developmental Processes in Drought-Stressed ArabidopsisTemporal transcriptome analysis during drought stress coupled with Bayesian network modeling reveals early drought signaling events and identifies AGL22 as a regulator of primary metabolism.
An Indexed, Mapped Mutant Library Enables Reverse Genetics Studies of Biological Processes in Chlamydomonas reinhardtiiA collection of green algal mutants with known insertion sites is presented and used to identify a Chlamydomonas gene important in green algal triacylglycerol biosynthesis.
RESEARCH ARTICLES
Genome Reduction Uncovers a Large Dispensable Genome and Adaptive Role for Copy Number Variation in Asexually Propagated Solanum tuberosumAsexually propagated potato shows greater copy number variation compared with sexually propagated plant species, with a strong connection to environmental response pathways.
Arabidopsis RNASE THREE LIKE2 Modulates the Expression of Protein-Coding Genes via 24-Nucleotide Small Interfering RNA-Directed DNA MethylationThe Arabidopsis RNaseIII enzyme RTL2 modulates the 24-nucleotide small interfering RNA repertoire and contributes to the regulation of protein-coding gene expression.
The Nuclear Ribonucleoprotein SmD1 Interplays with Splicing, RNA Quality Control, and Posttranscriptional Gene Silencing in ArabidopsisSmD1, a conserved component of the small nuclear ribonucleoprotein complex, participates in splicing and in the partitioning of aberrant RNAs between RNA quality control and RNA silencing pathways.
Balancing of B6 Vitamers Is Essential for Plant Development and Metabolism in ArabidopsisManipulating the levels of the vitamin B6 salvage enzyme PDX3 reveals that alterations in vitamin B6 homeostasis and nitrogen metabolism are linked.
An Untranslated cis-Element Regulates the Accumulation of Multiple C4 Enzymes in Gynandropsis gynandra Mesophyll CellsA short sequence motif that regulates mesophyll-specific accumulation of multiple enzymes is used in C4 photosynthesis.
Interactions of C4 Subtype Metabolic Activities and Transport in Maize Are Revealed through the Characterization of DCT2 MutantsC4 photosynthesis includes a complex set of pathways that were analyzed with genetic mutants through molecular and biochemical experiments in maize.
The Arabidopsis NRG2 Protein Mediates Nitrate Signaling and Interacts with and Regulates Key Nitrate RegulatorsArabidopsis NRG2, which regulates NRT1.1 and interacts with NLP7, mediates nitrate signaling.
The LSM1-7 Complex Differentially Regulates Arabidopsis Tolerance to Abiotic Stress Conditions by Promoting Selective mRNA DecappingA decapping activator complex ensures the adequacy and specificity of the response of Arabidopsis to different abiotic stresses by promoting selective mRNA degradation.
The Opposing Actions of Arabidopsis CHROMOSOME TRANSMISSION FIDELITY7 and WINGS APART-LIKE1 and 2 Differ in Mitotic and Meiotic CellsDetailed mutant analysis uncovers epistatic interactions between Arabidopsis CTF7 and WAPL, which help regulate sister chromatid cohesion during meiosis and mitosis.
Pectin Biosynthesis Is Critical for Cell Wall Integrity and Immunity in Arabidopsis thalianaLoss of UDP-glucuronate 4-epimerases GAE1 and GAE6 in Arabidopsis thaliana causes a dramatic reduction of pectin in the cell wall and compromised immunity to Pseudomonas syringae and Botrytis cinerea.
The Transmembrane Region of Guard Cell SLAC1 Channels Perceives CO2 Signals via an ABA-Independent Pathway in ArabidopsisA transmembrane region of the guard cell SLAC1 anion channel contains sites of CO2 signal perception, which could be different from the sites of ABA signal perception.
Reconstitution of CO2 Regulation of SLAC1 Anion Channel and Function of CO2-Permeable PIP2;1 Aquaporin as CARBONIC ANHYDRASE4 InteractorFunctional reconstitution of extracellular CO2 signaling to ion channel regulation is shown by expression of SLAC1, protein kinases, CARBONIC ANHYDRASE4, and interacting CO2-permeable PIP2;1 aquaporin in X. laevis oocytes.
MATE Transporter-Dependent Export of Hydroxycinnamic Acid AmidesA MATE transporter is required and sufficient for export of hydroxycinnamic acid amides, which act as antimicrobial compounds on the plant surface.
