Arabidopsis TANGLED identifies the division plane throughout mitosis and cytokinesis (2007)

Walker, Keely L, Müller, Sabine, Moss, Dorianne, Ehrhardt, David W, Smith, Laurie G

Background: In premitotic plant cells, the future division plane is predicted by a cortical ring of microtubules and F-actin called the preprophase band (PPB). The PPB persists throughout prophase,...

Real-time lineage analysis reveals oriented cell divisions associated with morphogenesis at the shoot apex of Arabidopsis thaliana (2004)

Reddy, G. Venugopala, Heisler, Marcus G., Ehrhardt, David W., Meyerowitz, Elliot M.

Precise knowledge of spatial and temporal patterns of cell division, including number and orientation of divisions, and knowledge of cell expansion, is central to understanding morphogenesis. Our...

Random GFP∷cDNA fusions enable visualization of subcellular structures in cells of Arabidopsis at a high frequency

Cutler, Sean R., Ehrhardt, David W., Griffitts, Joel S., Somerville, Chris R.

We describe a general approach for identifying components of subcellular structures in a multicellular organism by exploiting the ability to generate thousands of independent transformants in...

Polarized cytokinesis in vacuolate cells of Arabidopsis

Cutler, Sean R., Ehrhardt, David W.

The view of plant-cell cytokinesis commonly depicted in textbooks is of a symmetrical process, with the phragmoplast initiating in the center of the cell and growing outward to the parental cell...

Pharmacological Analysis of Nod Factor-Induced Calcium Spiking in Medicago truncatula. Evidence for the Requirement of Type IIA Calcium Pumps and Phosphoinositide Signaling1

Engstrom, Eric M., Ehrhardt, David W., Mitra, Raka M., Long, Sharon R.

Bacterial Nod factors trigger a number of cellular responses in root hairs of compatible legume hosts, which include periodic, transient increases in cytosolic calcium levels, termed calcium spiking....

The Arabidopsis SKU6/SPIRAL1 Gene Encodes a Plus End–Localized Microtubule-Interacting Protein Involved in Directional Cell ExpansionW⃞

Sedbrook, John C., Ehrhardt, David W., Fisher, Sarah E., Scheible, Wolf-Rüdiger, Somerville, Chris R.

The sku6-1 mutant of Arabidopsis thaliana exhibits altered patterns of root and organ growth. sku6 roots, etiolated hypocotyls, and leaf petioles exhibit right-handed axial twisting, and root growth...

Evidence for High-Capacity Bidirectional Glucose Transport across the Endoplasmic Reticulum Membrane by Genetically Encoded Fluorescence Resonance Energy Transfer Nanosensors

Fehr, Marcus, Takanaga, Hitomi, Ehrhardt, David W., Frommer, Wolf B.

Glucose release from hepatocytes is important for maintenance of blood glucose levels. Glucose-6-phosphate phosphatase, catalyzing the final metabolic step of gluconeogenesis, faces the endoplasmic...

Systematic Analysis of Arabidopsis Organelles and a Protein Localization Database for Facilitating Fluorescent Tagging of Full-Length Arabidopsis Proteins1[W]

Li, Shijun, Ehrhardt, David W., Rhee, Seung Y.

Cells are organized into a complex network of subcellular compartments that are specialized for various biological functions. Subcellular location is an important attribute of protein function. To...

Morlin, an inhibitor of cortical microtubule dynamics and cellulose synthase movement

DeBolt, Seth, Gutierrez, Ryan, Ehrhardt, David W., Melo, Carlos V., Ross, Loretta, Cutler, Sean R., ...

Morlin (7-ethoxy-4-methyl chromen-2-one) was discovered in a screen of 20,000 compounds for small molecules that cause altered cell morphology resulting in swollen root phenotype in Arabidopsis....

Nonmotile Cellulose Synthase Subunits Repeatedly Accumulate within Localized Regions at the Plasma Membrane in Arabidopsis Hypocotyl Cells following 2,6-Dichlorobenzonitrile Treatment1[W]
