Unregulated Sphingolipid Biosynthesis in Gene-Edited Arabidopsis ORM Mutants Results in Nonviable Seeds with Strongly Reduced Oil ContentRemoving the regulation of sphingolipid biosynthesis by completely knocking out Orosomucoid-like protein (ORM) genes results in ceramide hyperaccumulation and nonviable seeds with strongly reduced oil content.
Coordinated Activation of ARF1 GTPases by ARF-GEF GNOM Dimers Is Essential for Vesicle Trafficking in ArabidopsisARF-GEF GNOM of Arabidopsis occurs as a dimer and mediates coordinated activation of ARF1 GTPases required for membrane vesicle formation.
FRA1 Kinesin Modulates the Lateral Stability of Cortical Microtubules through Cellulose Synthase–Microtubule Uncoupling ProteinsThe FRA1 kinesin affects the positional stability of its tracks by regulating the levels of CMU proteins available to bind to cortical microtubules.
The miR396-GRFs Module Mediates the Prevention of Photo-oxidative Damage by Brassinosteroids during Seedling De-Etiolation in ArabidopsisBRs play important roles in the transition from skotomorphogenesis to photomorphogenesis by optimizing the biosynthesis of chlorophyll through the BZR1-PIF4-GRF7 transcriptional complex.
STARCH SYNTHASE5, a Noncanonical Starch Synthase-Like Protein, Promotes Starch Granule Initiation in ArabidopsisA widely conserved but noncatalytic starch synthase-like protein interacts with the known granule-initiating factor MRC and regulates the number of starch granules formed in chloroplasts.
Zipcode RNA-Binding Proteins and Membrane Trafficking Proteins Cooperate to Transport Glutelin mRNAs in Rice EndospermGlutelin mRNAs are transported on endosomes through the direct interactions of two RNA-binding proteins with two membrane-trafficking factors.
Dual-Reporting Transcriptionally Linked Genetically Encoded Fluorescent Indicators Resolve the Spatiotemporal Coordination of Cytosolic Abscisic Acid and Second Messenger Dynamics in ArabidopsisMultiparametric in vivo analyses using dual-reporting genetically encoded fluorescent indicators reveal the spatiotemporal coordination of signaling compound dynamics in Arabidopsis roots.
A Pair of Arabidopsis Diacylglycerol Kinases Essential for Gametogenesis and Endoplasmic Reticulum Phospholipid Metabolism in Leaves and FlowersDiacylglycerol kinases DGK2 and DGK4 produce phosphatidic acid at the ER for signaling in pollen tube growth and for the biosynthesis of phosphatidylglycerol in leaves of Arabidopsis.
Differential Phosphorylation of the Transcription Factor WRKY33 by the Protein Kinases CPK5/CPK6 and MPK3/MPK6 Cooperatively Regulates Camalexin Biosynthesis in ArabidopsisThe pathogen-responsive protein kinases CPK5/CPK6 and MPK3/MPK6 cooperatively regulate camalexin biosynthesis upon pathogen infection via differential phosphorylation of the transcription factor WRKY33.
Structure–Function Analysis of SMAX1 Reveals Domains That Mediate Its Karrikin-Induced Proteolysis and Interaction with the Receptor KAI2Karrikins trigger degradation of SMAX1 through an F-box protein–mediated mechanism that is highly similar to strigolactone signaling.
