Induction of Pre-Infection Thread Structures in the Leguminous Host Plant by Mitogenic Lipo-Oligosaccharides of Rhizobium
Root nodules of leguminous plants are symbiotic organs in which Rhizobium bacteria fix nitrogen and a common morphogenetic pathway may be shared in the formation of root hairs and infection threads. Expand
Cell biological changes of outer cortical root cells in early determinate nodulation.
Early nodulation stages in common bean and Lotus japonicus are studied to show the role of cytoplasmic bridges and the influence of rhizobial Nod factors on this phenomenon, and the sensitivity of the nodulation process to ethylene. Expand
Salicylic acid inhibits indeterminate-type nodulation but not determinate-type nodulation.
Salicylic acid (SA) did not act systemically, and only biologically active SA derivatives were capable of inhibiting nodule formation, suggesting that SA may be a useful tool for studying fundamental differences between signal transduction pathways of indeterminate- and determinate-type nodulating plants.

Nod factors produced by Rhizobium leguminosarum biovar viciae induce ethylene-related changes in root cortical cells of Vicia sativa ssp. nigra.
Vicia sativa ssp. nigra plants develop the "Thick short root" (Tsr) phenotype when both (i) the roots are inoculated with the root nodule inducing bacterium Rhizobium leguminosarum biovar viciae, andExpand
Accumulation of lipochitin oligosaccharides and NodD-activating compounds in an efficient plant--Rhizobium nodulation assay.
This work describes the accumulation of LCOs in an efficient nodulation assay with Vicia sativa subsp. Expand
Cell wall degradation during infection thread formation by the root nodule bacterium Rhizobium leguminosarum is a two-step process.
It is proposed that a two-step cell wall degradation process for infection thread formation is proposed, the first step is a local cell wall modification by plant enzymes, induced by rhizobial Nod factors, and the second step is completecell wall degradation in the presence of rhizobia. Expand
Modelling the dynamics of polar auxin transport in inflorescence stems of Arabidopsis thaliana
Highlight An experimental and mathematical approach to polar auxin transport results in a model based on an extended general advection–diffusion equation including auxin immobilization andExpand
Cell Division in Nautilocalyx Explants III. Effects of 2,6-dichlorobenzonitrile on Phragmosome, Band of Microtubules and Cytokinesis.
Results indicate that the DCB-inhibition of cytokinesis does not result from interference with phragmosome and BMT, two structures which are probably involved in cytokineses and in the determination of the plane of cell division. Expand
