- Soybean DICER-LIKE2 Regulates Seed Coat Color via Production of Primary 22-Nucleotide Small Interfering RNAs from Long Inverted Repeats
Soybean DCL2 favors long inverted repeat-derived double-stranded RNA as its substrate and generates primary 22-nucleotide siRNAs to regulate seed coat color and silence transposable elements.
LARGE-SCALE BIOLOGY ARTICLES
- ARADEEPOPSIS, an Automated Workflow for Top-View Plant Phenomics using Semantic Segmentation of Leaf States
ARADEEPOPSIS is a robust, open-source, and easy-to-use pipeline to extract plant phenotypic traits and to classify leaf states from large-scale image data.
- Alternative Crassulacean Acid Metabolism Modes Provide Environment-Specific Water-Saving Benefits in a Leaf Metabolic Model
Stoichiometric modeling of leaf metabolism reveals metabolic and morphological determinants for introducing Crassulacean acid metabolism and alternative water-saving flux modes into a C3 leaf in different environments.
RESEARCH ARTICLES
- Temporal Regulation of the Metabolome and Proteome in Photosynthetic and Photorespiratory Pathways Contributes to Maize Heterosis
Hybrids optimize metabolic abundance through diurnal nonadditive expression of key enzymes in photosynthetic and photorespiratory pathways to enhance photosynthetic efficiency and plant growth.
- Allelic Variation of MYB10 Is the Major Force Controlling Natural Variation in Skin and Flesh Color in Strawberry (Fragaria spp.) Fruit
Independent mutations in the transcription factor MYB10 cause most of the anthocyanin variation observed in diploid woodland strawberry (Fragaria vesca) and octoploid cultivated strawberry (Fragaria × ananassa).
- Ectopic Expression of the Transcriptional Regulator silky3 Causes Pleiotropic Meristem and Sex Determination Defects in Maize Inflorescences
Ectopic expression of silky3 in maize inflorescence interferes with multiple flower-related molecular pathways and causes pleiotropic defects in the meristems, floral organs, and sex development.
- SPIKE1 Activates the GTPase ROP6 to Guide the Polarized Growth of Infection Threads in Lotus japonicus
SPIKE1, a DOCK family guanine nucleotide exchange factor, interacts with and activates the GTPase LjROP6 to mediate the polar progression of infection threads in Lotus japonicus.
- SAUR17 and SAUR50 Differentially Regulate PP2C-D1 during Apical Hook Development and Cotyledon Opening in Arabidopsis
SAUR17 is highly expressed in apical hooks and cotyledons in the dark, where it promotes etiolation by protecting the phosphatase activity of PP2C-D1 against cell expansion–inducing SAURs such as SAUR50.
- Transcriptional Regulation of PLETHORA1 in the Root Meristem Through an Importin and Its Two Antagonistic Cargos
JANUS connects RNA polymerase II (Pol II) with PLT1 to promote the autotranscription of PLT1 while GIF1 titrates JANUS away from Pol II by competitive binding.
- Substrate Specificity of LACCASE8 Facilitates Polymerization of Caffeyl Alcohol for C-Lignin Biosynthesis in the Seed Coat of Cleome hassleriana
LACCASE8 from the model system Cleome hassleriana possesses the unusual property of oxidizing caffeyl alcohol but not coniferyl alcohol and plays a critical role in initiating C-lignin polymerization.
- Molecular Mechanism Underlying the Synergetic Effect of Jasmonate on Abscisic Acid Signaling during Seed Germination in Arabidopsis
JAZ repressors of the jasmonic acid (JA) pathway directly regulate abscisic acid (ABA)–responsive transcription factors to integrate JA and ABA signals during germination and post-germinative growth.
- M-Type Thioredoxins Regulate the PGR5/PGRL1-Dependent Pathway by Forming a Disulfide-Linked Complex with PGRL1
Chloroplast m-type thioredoxins interact with PGRL1 and regulate the PGR5/PGRL1-dependent PSI cyclic pathway.
- Chloroplast Chaperonin-Mediated Targeting of a Thylakoid Membrane Protein
The chloroplast chaperonin captures and releases Plastidic type I signal peptidase 1 during targeting of the peptidase to the thylakoid membrane.
- Abscisic Acid-Triggered Persulfidation of the Cys Protease ATG4 Mediates Regulation of Autophagy by Sulfide
Hydrogen sulfide negatively regulates the progress of autophagy through persulfide modification of the Arabidopsis AtATG4a protease.
- Regulation of Aluminum Resistance in Arabidopsis Involves the SUMOylation of the Zinc Finger Transcription Factor STOP1
The Al-resistance transcription factor STOP1 is mono-SUMOylated at K40, K212, or K395 sites and deSUMOylated by the SUMO protease ESD4, which is involved in the regulation of Al resistance in Arabidopsis.
- AUTOPHAGY-RELATED14 and Its Associated Phosphatidylinositol 3-Kinase Complex Promote Autophagy in Arabidopsis
Genetic analysis of the Arabidopsis VPS34 PI3K complex through the ATG14 or VPS38 subunits revealed a preferential role for ATG14 during autophagy and the widespread importance of PI3P in plants.
- Grass-Specific EPAD1 Is Essential for Pollen Exine Patterning in Rice
Rice lipid binding protein EPAD1 is a male meiocyte-derived determinant that controls grass-specific pollen exine pattern formation by maintaining primexine integrity.
- The Cotton Wall-Associated Kinase GhWAK7A Mediates Responses to Fungal Wilt Pathogens by Complexing with the Chitin Sensory Receptors
GhWAK7A interacts with the GhCERK1-GhLYK5 chitin sensory complex and regulates cotton resistance against fungal diseases.
- Diverse Roles of the Salicylic Acid Receptors NPR1 and NPR3/NPR4 in Plant Immunity
Perception of SA by its receptors is required for activation of NHP biosynthesis during SAR, plays crucial roles in PTI and ETI, and is involved in regulating SA 5-hydroxylation and glycosylation.
