Divergent Functional Diversification Patterns in the SEP/AGL6/AP1 MADS-Box Transcription Factor SupercladeFunctional analysis of the petunia MADS-box gene SEP/AGL6/AP1 superclade compared to Arabidopsis and other species suggests major differences in the functional diversification of its members during evolution.
Dual Activities of Plant cGMP-Dependent Protein Kinase and Its Roles in Gibberellin Signaling and Salt StressPlant cGMP-dependent protein kinase has both kinase and phosphatase activities and regulates the nucleocytoplasmic distribution of the GAMYB transcription factor, modulating gibberellin signaling.
A Promiscuous CYP706A3 Reduces Terpene Volatile Emission from Arabidopsis Flowers, Affecting Florivores and the Floral MicrobiomeA gene cluster encoding two promiscuous enzymes modulates volatile emissions from Arabidopsis thaliana flowers, formation of insect-deterring terpene oxides, and the composition of the floral microbiome.
ORANGE Represses Chloroplast Biogenesis in Etiolated Arabidopsis Cotyledons via Interaction with TCP14Arabidopsis ORANGE, a DnaJ-like zinc finger domain protein, represses chloroplast biogenesis in dark-germinated cotyledons by interacting with the transcription factor TCP14 in the nucleus.
Secretion of Phospholipase Dδ Functions as a Regulatory Mechanism in Plant Innate ImmunityMembrane microdomains and PLDδ exocytosis regulate PLDδ accumulation during penetration resistance in plant innate immunity.
Genetic Analyses of the Arabidopsis ATG1 Kinase Complex Reveal Both Kinase-Dependent and Independent Autophagic Routes during Fixed-Carbon StarvationCharacterization of quadruple mutants eliminating ATG1 reveals that prolonged fixed-carbon starvation induces an ATG1 kinase-independent autophagic route in Arabidopsis.
A GDSL Esterase/Lipase Catalyzes the Esterification of Lutein in Bread WheatThe discovery of an apoplastic enzyme responsible for esterifying carotenoids that is unexpectedly spatially separated from its plastidic substrate, lutein, affords new ways to biofortify crops.
Photosystem Biogenesis Is Localized to the Translation Zone in the Chloroplast of ChlamydomonasPathways that converge for photosystem biogenesis occur in a specific region of the chloroplast called the T-zone in Chlamydomonas.
Intra-Kernel Reallocation of Proteins in Maize Depends on VP1-Mediated Scutellum Development and Nutrient AssimilationVP1 directly regulates embryo scutellum development and nutrient assimilation, which is required for protein reallocation from the endosperm to embryo.
Ribosome-Associated Chloroplast SRP54 Enables Efficient Cotranslational Membrane Insertion of Key Photosynthetic ProteinsRibosome profiling combined with biochemical studies demonstrates that chloroplast SRP54 contacts ribosomal uL4 and enhances cotranslational insertion of thylakoid membrane proteins.
