In the early response of Arabidopsis roots to ethylene, cell elongation is up- and down-regulated and uncoupled from differentiation.
Slight changes in the concentration of ethylene in the environment modulate the elongation of target cells in the root epidermis of Arabidopsis. The response is immediate, concentration dependent,Expand

In Vivo Colocalization of Xyloglucan Endotransglycosylase Activity and Its Donor Substrate in the Elongation Zone of Arabidopsis Roots
We have developed a method for the colocalization of xyloglucan endotransglycosylase (XET) activity and the donor substrates to which it has access in situ and in vivo. Sulforhodamine conjugates ofExpand

Root hair initiation is coupled to a highly localized increase of xyloglucan endotransglycosylase action in Arabidopsis roots.
Root hairs are formed by two separate processes: initiation and subsequent tip growth. Root hair initiation is always accompanied by a highly localized increase in xyloglucan endotransglycosylaseExpand

Cell walls at the plant surface behave mechanically like fiber-reinforced composite materials.
Using extensiometry and polarization confocal microscopy, we provide here the first confirming evidence that the mean orientation of cellulose fibrils in the composite wall determines its mechanicalExpand

Identification of the tumor metastasis suppressor Nm23-H1/Nm23-R1 as a constituent of the centrosome.
Processes like cell proliferation, differentiation, and tumor metastasis require a flexible adaptation of cell shape and cell plasticity. A regulator of cell structure and shape is the centrosome andExpand

Ion fluxes, auxin and the induction of elongation growth in Nicotiana tabacum cells.
Immobilized cultured tobacco cells become polarized upon the addition of naphthalene-1-acetic acid and start to elongate from an initial spherical shape. The question as to how a diffuse-growing cellExpand

Nucleoside diphosphate kinase beta (Nm23-R1/NDPKbeta) is associated with intermediate filaments and becomes upregulated upon cAMP-induced differentiation of rat C6 glioma.
Nucleoside diphosphate kinases (Nm23/NDPK) are enzymes functional in cell proliferation, differentiation, development, tumor progression, and metastasis. Nevertheless, no consensus exists about theExpand

Expression of circaseptan and circannual rhythmicity in the imbibition of dry stored bean seeds.
Water uptake of seeds of Phaseolus vulgaris L. cv Limburg was monitored in a controlled atmosphere every day at solar noon for a period of 2 years. The imbibition rate, determined as the mean of fiveExpand

Phosphatidylinositol 3‐kinase activity is required for the expression of glial fibrillary acidic protein upon cAMP‐dependent induction of differentiation in rat C6 glioma
Glial fibrillary acidic protein (GFAP) is an intermediate filament (IF) protein expressed upon maturation of astrocytes and upregulated during reactive astrogliosis. Its expression is modulated byExpand

Datura stramonium Agglutinin : Location in the Seed and Release upon Imbibition.
The distribution of Datura stramonium agglutinin over different tissues of D. stramonium L. seeds was visualized by immunocytochemical techniques and quantified by agglutination assays. The lectinExpand
