Summary • The role of phosphoinositide-specific phospholipase C (PI-PLC) signaling in the macrotubule-dependent protoplast volume regulation in plasmolyzed root cells of Triticum turgidum was investigated. • At the onset of hyperosmotic stress, P

Two modes of endocytosis are known to occur in eucaryotic cells: fluid phase and receptor-mediated endocytosis. Fluid-phase endocytosis in plant cells resembles the retrieval of excess plasma membrane material previously incorporated by exocytosis. P

Cortical actin filament (AF) organization was studied in detail in developing stomatal complexes of the grasses Zea mays and Triticum turgidum. AF arrays during the whole stomatal complex development are dynamic, partly following the pattern of corti

Endoplasmic reticulum (ER) organization in the dividing cells of the pterophyte Asplenium nidus and of the gymnosperms Pinus brutia and Pinus nigra has been studied by immunolocalization techniques using the monoclonal antibody 2E7, which recognizes

Rapid activation of phospholipase A (PLA) by auxin or plant-pathogen interaction suggests a function in signal transduction for this enzyme, but the molecular identification of a cytosolic PLA carrying out this function remains open. We isolated four

Tobacco pollen tubes were used as a standard in vitro system to investigate cell growth aberrations caused by some of the Multicentre Evaluation of In Vitro Cytotoxicity (MEIC) programme chemicals and other toxic compounds. Changes in cytoskeletal pa

The Escherichia coli porin OmpG, which acts as an efficient unspecific channel for mono-, di- and trisaccharides, has been purified and crystallized in two dimensions. Projection maps of two different crystal forms of OmpG at 6 A resolution show that

In a previous structure-activity analysis of chlorophenol and nitrophenol toxicity, the pollen tube growth test was shown to discriminate between oxidative uncoupling and narcotic mechanisms of action. To examine the suitability of the use of pollen

We demonstrate here the possibility of endosperm development in vitro after the fusion of pairs of an isolated sperm and an isolated central cell of maize. The occurrence of karyogamy and the time course of the fusion of sperm and central cell nuclei

Summary Cell division in Prorocentrum micans was studied with TEM, SEM and with fluorescence microscope techniques to visualize cytoskeletal structures. The cleavage furrow consists of the plasma membrane and two valvar vesicles. Its leading edge is
