Elevated CO2 induces physiological, biochemical and structural changes in leaves of Arabidopsis thaliana.
TLDR
Results suggest that the changes in chloroplast ultrastructure may primarily be a consequence of increased starch accumulation, and the reductions in mineral nutrient concentrations may be a result of dilution by increased concentrations of carbohydrates and also of decreases in stomatal conductance and transpiration rate.
Pollen dispersion, pollen viability and pistil receptivity in Leymus chinensis.
TLDR
The data suggest that low pollen viability, short pollen longevity and short pistil receptivity all appear to contribute to the low seed production typical of this important forage crop.
The Signal Transducer NPH3 Integrates the Phototropin1 Photosensor with PIN2-Based Polar Auxin Transport in Arabidopsis Root Phototropism[C][W]
TLDR
BL-induced root phototropism is based on the phot1/NPH3 signaling pathway, which stimulates the shootward auxin flux by modifying the subcellular targeting of PIN2 in the root apex transition zone.
Single-Molecule Analysis of PIP2;1 Dynamics and Partitioning Reveals Multiple Modes of Arabidopsis Plasma Membrane Aquaporin Regulation[C][W]
TLDR
It is demonstrated that PIP2;1 molecules are heterogeneously distributed on the plasma membrane and that clathrin and membrane raft pathways cooperate to mediate the subcellular trafficking of PIP1;1, suggesting that the dynamic partitioning and recycling pathways might be involved in the multiple modes of regulating water permeability.
Carbon nanotubes as molecular transporters for walled plant cells.
TLDR
Confocal fluorescence images revealed the cellular uptake of both SWNT/fluorescein isothiocyanate andSWNT/DNA conjugates, demonstrating that SWNTs also hold great promise as nanotransporters for walled plant cells.
Disruption of actin filaments by latrunculin B affects cell wall construction in Picea meyeri pollen tube by disturbing vesicle trafficking.
TLDR
The results indicate that depolymerization of AFs affects the distribution and configuration of cell wall components in Picea meyeri pollen tube by disturbing vesicle trafficking.
Clathrin and Membrane Microdomains Cooperatively Regulate RbohD Dynamics and Activity in Arabidopsis[C][W]
TLDR
This work used single-particle tracking analysis to detect the dynamics of GFP-RbohD in Arabidopsis and demonstrated that clathrin- and microdomain-dependent endocytic pathways cooperatively regulate R bohD dynamics.
Arabidopsis R-SNARE Proteins VAMP721 and VAMP722 Are Required for Cell Plate Formation
TLDR
Observations suggest that VAMP721 and Vamp722 are involved in secretory trafficking to the plasma membrane via TGN/early endosomal compartment, which contributes substantially to cell plate formation during plant cytokinesis.
Lipid microdomain polarization is required for NADPH oxidase-dependent ROS signaling in Picea meyeri pollen tube tip growth.
TLDR
The results suggest that the polarization of lipid microdomains to the apical plasma membrane, and the inclusion of NOX into these domains, contribute, at least in part, to the ability to grow in a highly polarized manner to form pollen tubes.
Analysis of interactions among the CLAVATA3 receptors reveals a direct interaction between CLAVATA2 and CORYNE in Arabidopsis.
TLDR
The subcellular localization of CRN is demonstrated and the interactions among CLV1, CLV2, and CRN using firefly luciferase complementation imaging assays are analyzed to provide new insights into the CLV3 signaling pathway.
