BREAKTHROUGH REPORT
Establishment of Proximity-Dependent Biotinylation Approaches in Different Plant Model SystemsA systematic study applying a variety of biotin-based proximity labeling approaches in several plant systems using various conditions and bait proteins.
Evolutionary Variation in MADS Box Dimerization Affects Floral Development and Protein Abundance in MaizeEvolutionary variants of B-class MADS box transcription factors differentially affect MADS box complex degradation and cause quantitative variation in anther shape in maize.
Vascular Bundles Mediate Systemic Reactive Oxygen Signaling during Light StressThe reactive oxygen species wave propagates through vascular bundles during the systemic response of Arabidopsis (Arabidopsis thaliana) plants to excess light stress.
A Fully Functional ROP Fluorescent Fusion Protein Reveals Roles for This GTPase in Subcellular and Tissue-Level PatterningTagging ROP in the middle of the protein produces a functional protein that provides all ROP function in juvenile moss tissues and marks sites with weakened cell walls long before expansion occurs.
RESEARCH ARTICLES
Developmental Genetics of Corolla Tube Formation: Role of the tasiRNA-ARF Pathway and a Conceptual ModelWe show that the tasiRNA-ARF pathway is required for corolla tube formation in monkeyflowers (Mimulus) and propose a new conceptual model highlighting the central role of auxin-directed synchronized growth in congenital petal fusion.
Structural Insight into DNA Recognition by CCT/NF-YB/YC Complexes in Plant Photoperiodic FloweringOur results suggested that CCT domain-containing proteins from three families can form trimer with NF-YB/YC and revealed the DNA recognition mechanism of CCT/NF-YB/YC complex.
Auxin Regulates Sucrose Transport to Repress Petal Abscission in Rose (Rosa hybrida)Auxin modulates sucrose transport to repress petal abscission in rose, and this process is regulated by a RhARF7-RhSUC2 module in the abscission zone.
Sterile Spikelets Contribute to Yield in Sorghum and Related GrassesApparently nonfunctional floral structures (spikelets) provide carbon for the developing grain in sorghum and two related wild species, thereby contributing to yield (fitness).
The Transcription Factor NIGT1.2 Modulates Both Phosphate Uptake and Nitrate Influx during Phosphate Starvation in Arabidopsis and MaizeNIGT1.2 plays an important role in modulating low-Pi-dependent uptake of phosphate and nitrate, tending towards maintenance of the phosphorus to nitrogen balance in plants during Pi starvation.
A DNA Methylation Reader–Chaperone Regulator–Transcription Factor Complex Activates OsHKT1;5 Expression during Salinity StressOsSUVH7, OsBAG4, and OsMYB106 form a DNA methylation reader–chaperone regulator–transcription factor complex on the promoter region of OsHKT1;5 to activate its expression during salinity stress.
The Transcription Factor bZIP60 Links the Unfolded Protein Response to the Heat Stress Response in MaizeThe transcription factor bZIP60 links a system that alerts plants to problems in protein folding to a system that protects plants from heat stress.
Mutations in the Pectin Methyltransferase QUASIMODO2 Influence Cellulose Biosynthesis and Wall Integrity in ArabidopsisPhysical and functional interactions between pectin and cellulose are required for normal wall assembly and plant growth, as revealed in analyses of mutants for a pectin methyltransferase.
Endocytosis of BRASSINOSTEROID INSENSITIVE1 Is Partly Driven by a Canonical Tyr-Based MotifCanonical Tyr endocytic motifs are functional in plants and control the internalization of plasma membrane proteins by the clathrin adaptor complex AP-2.
Differential Activation of Partially Redundant Δ9 Stearoyl-ACP Desaturase Genes Is Critical for Omega-9 Monounsaturated Fatty Acid Biosynthesis During Seed Development in ArabidopsisOleic acid and derivatives synthesized by four Δ9 stearoyl-ACP desaturases, FAB2, AAD1, AAD5, and AAD6, play critical roles during Arabidopsis embryo development and seed maturation.
