LARGE-SCALE BIOLOGY ARTICLE
AspWood: High-Spatial-Resolution Transcriptome Profiles Reveal Uncharacterized Modularity of Wood Formation in Populus tremulaThe AspWood large-scale data set comprises high-spatial-resolution RNA-seq transcriptome profiles collected across the phloem-cambium-xylem developmental zone of aspen trees.
RESEARCH ARTICLES
Divergence of the Floral A-Function between an Asterid and a Rosid SpeciesPetunia research suggests that the mechanisms controlling the spatial restriction of floral organ identity genes are more diverse than the well-conserved B and C floral organ identity functions.
Maize YABBY Genes drooping leaf1 and drooping leaf2 Regulate Plant ArchitectureMaize drooping leaf genes are necessary for proper leaf development and reside within quantitative trait locus regions for agronomically important leaf architecture traits.
ZHOUPI and KERBEROS Mediate Embryo/Endosperm Separation by Promoting the Formation of an Extracuticular Sheath at the Embryo SurfaceA cysteine-rich peptide, KERBEROS, acts downstream of the transcription factor ZHOUPI to modify the embryo-endosperm interface and mediate the separation of these two tissues during seed development.
Homologs of PROTEIN TARGETING TO STARCH Control Starch Granule Initiation in Arabidopsis LeavesTwo plastidial coiled coil-containing proteins play a critical role in delivering suitable maltooligosaccharide primers to STARCH SYNTHASE4 during starch granule initiation.
A Plastid Phosphatidylglycerol Lipase Contributes to the Export of Acyl Groups from Plastids for Seed Oil BiosynthesisPLIP1, a plastid lipase specific for a unique chloroplast lipid, phosphatidylglycerol tagged with 16:1 trans fatty acid, is involved in acyl exchange and fatty acid export for seed oil biosynthesis.
Meiotic Chromosome Association 1 Interacts with TOP3α and Regulates Meiotic Recombination in RiceMEICA1 interacts with TOP3α and plays pivotal roles in processing recombination intermediates and limiting meiotic crossover formation during rice meiosis.
Polyprenols Are Synthesized by a Plastidial cis-Prenyltransferase and Influence Photosynthetic PerformanceA plastidial cis-prenyltransferase synthesizes a family of polyprenols that accumulate in thylakoid membranes and play a central role in the efficiency of photosynthetic performance.
Suppressors of the Chloroplast Protein Import Mutant tic40 Reveal a Genetic Link between Protein Import and Thylakoid BiogenesisGenetic analyses identify the chloroplast proteins ALB4 and STIC2 as coactors in a specialized thylakoid protein targeting pathway, and a link between envelope translocation and thylakoid targeting.
A Lipid-Anchored NAC Transcription Factor Is Translocated into the Nucleus and Activates Glyoxalase I Expression during Drought StressUnder drought stress, lipid-anchored MfNACsa translocates to the nucleus by thioesterase MtAPT1-dependent de-S-palmitoylation, regulating GlyI gene expression and GSH/GSSG ratio.
Arabidopsis ATRX Modulates H3.3 Occupancy and Fine-Tunes Gene ExpressionThe Alpha Thalassemia-mental Retardation X-linked homolog functions as a H3.3 chaperone and modulates gene expression in Arabidopsis.
