LARGE-SCALE BIOLOGY ARTICLES
- Deep Conservation of cis-Element Variants Regulating Plant Hormonal Responses
Regulatory element variants and their flanking sequences are highly conserved in promoters of hormonal response genes, where different sequence variants define the hormonal response profile.
- Integrative Analysis from the Epigenome to Translatome Uncovers Patterns of Dominant Nuclear Regulation during Transient Stress
Profiling of 11 genome-wide outputs of gene regulation in response to hypoxia reveals multiple aspects of nuclear and whole-cell epigenetic and posttranscriptional gene regulation in Arabidopsis.
RESEARCH ARTICLES
- Origin and Evolution of Diploid and Allopolyploid Camelina Genomes Were Accompanied by Chromosome Shattering
Camelina allopolyploid genomes originated through recurrent hybridization between two paleogenomes; descending dysploidies in Camelina were accompanied by complex chromosome shattering.
- Intra-Kernel Reallocation of Proteins in Maize Depends on VP1-Mediated Scutellum Development and Nutrient Assimilation
VP1 directly regulates embryo scutellum development and nutrient assimilation, which is required for protein reallocation from the endosperm to embryo.
- OsCASP1 Is Required for Casparian Strip Formation at Endodermal Cells of Rice Roots for Selective Uptake of Mineral Elements
Casparian strips at the endodermis of roots mediate the selective uptake of mineral elements in rice by preventing apoplastic flow and have impacts on transporter protein abundance.
- Photoreceptor Activity Contributes to Contrasting Responses to Shade in Cardamine and Arabidopsis Seedlings
The lack of a shade-induced hypocotyl elongation response in Cardamine hirsuta results from the enhanced repressor activity of the phytochrome A photoreceptor.
- AvrRpm1 Functions as an ADP-Ribosyl Transferase to Modify NOI Domain-Containing Proteins, Including Arabidopsis and Soybean RPM1-Interacting Protein4
The Pseudomonas syringae effector protein AvrRpm1 ADP ribosylates RIN4 proteins from Arabidopsis and soybean, which promotes association of RIN4 with EXO70E2 and suppression of callose deposition.
- BRASSINOSTEROID-INSENSITIVE2 Negatively Regulates the Stability of Transcription Factor ICE1 in Response to Cold Stress in Arabidopsis
The protein kinase BIN2 interacts with and phosphorylates INDUCER OF CBF EXPRESSION1 under cold stress, accelerating its proteasome-mediated degradation to negatively regulate freezing tolerance.
- The Formation of a Camalexin Biosynthetic Metabolon
In Arabidopsis, the cytochrome P450 enzymes of the biosynthetic pathway for the antifungal compound camalexin form a metabolic complex to which the GSTU4 is recruited.
- Diurnal Regulation of Plant Epidermal Wax Synthesis through Antagonistic Roles of the Transcription Factors SPL9 and DEWAX
The Arabidopsis (Arabidopsis thaliana) transcription factors SPL9 and DEWAX act antagonistically to regulate rhythmic CER1 expression and diurnal wax synthesis.
- Ribosome-Associated Chloroplast SRP54 Enables Efficient Cotranslational Membrane Insertion of Key Photosynthetic Proteins
Ribosome profiling combined with biochemical studies demonstrates that chloroplast SRP54 contacts ribosomal uL4 and enhances cotranslational insertion of thylakoid membrane proteins.
- The MYB Activator WHITE PETAL1 Associates with MtTT8 and MtWD40-1 to Regulate Carotenoid-Derived Flower Pigmentation in Medicago truncatula
The R2R3 MYB activator WP1 associates with MtTT8 and MtWD40-1 and regulates floral carotenoid pigmentation by directly modulating carotenogenic gene expression in Medicago truncatula.
- Metabolically Distinct Pools of Phosphatidylcholine Are Involved in Trafficking of Fatty Acids out of and into the Chloroplast for Membrane Production
Chloroplast lysophosphatidylcholine acyltransferases are involved in PC acyl editing with newly synthesized fatty acids, and not in lysophosphatidylcholine transport for galactolipid synthesis.
- ABCC Transporters Mediate the Vacuolar Accumulation of Crocins in Saffron Stigmas
A transportomics approach allows identification of crocin vacuolar transporters from saffron stigmas.
