SummaryThe formation of wall appositions (plugs) by ionophore A 23187, CaCl2, LaCl3, and nifedipine was studied in mature internodal cells of characeaen algae. CaCl2 at concentrations above 10−2M induces thick fibrillar plugs without callose inNitella flexilis. InChara corallina andNitella flexilis ionophore A 23187 (1.25×10−5 to 5×10−5M) and LaCl3 (7.5×10−5 to 2.5×10−4M) cause flat appositions which contain callose and have a more granular structure. Plug formation by ionophore A 23187, CaCl2… Expand

Rapid wound responses ofSaprolegnia ferax hyphae depend upon actin and Ca2+-involving deposition of callose plugs
TLDR
This wound response is qualitatively similar to the production of septa which isolate developing sporangia and seal severed hyphae, indicating the use of a normal basic cellular developmental system as a protective mechanism against environmental damage. Expand
The characean internodal cell as a model system for studying wound healing
TLDR
It is shown that quickly growing fibrillar wound walls, even when deposited in the absence of microtubules, have a highly ordered helical structure of consistent handedness comprised of cellulose microfibrils. Expand
Injury toNitella internodal cells alters microtubule organization but microtubules are not involved in the wound response
TLDR
Analyzing the arrangement and relative stability of cortical microtubules during and after wound induction in internodal cells of Nitella flexilis andNitella pseudoflabellata indicates that micro Tubules are neither involved in vesicle transport nor the construction of cellulosic wound walls. Expand
Characean internodal cells as a model system for the study of cell organization.
TLDR
Giant internodal cells of characean green algae have been widely used for studying cellular physiology and their significance for understanding cytoarchitecture and cytoplasmic reorganization is emphasized. Expand
Actin-dependent deposition of putative endosomes and endoplasmic reticulum during early stages of wound healing in characean internodal cells.
TLDR
It is indicated that active actin-dependent deposition of putative recycling endosomes is required for wound healing (plasma membrane repair) and supports the hypothesis that deposition of ER cisternae helps to restore wounding-disturbed Ca(2+) metabolism. Expand

CHLORTETRACYCLINE‐INDUCED FORMATION OF WALL APPOSITIONS (CALLOSE PLUGS) IN INTERNODAL CELLS OF NITELLA FLEXILIS (CHARACEAE) 1
TLDR
The failure to produce a wound wall beneath CTC‐induced plugs appears to be related to the lower number of coated vesicles during plug formation, and the possible significance of the partially coated reticulum in plug and wound wall formation is discussed. Expand
Tetracyclines, verapamil and nifedipine induce callose deposition at specific cell sites in Riella helicophylla
TLDR
It is suggested as a working hypothesis that verapamil-induced CSR-callose synthesis is caused by a local change in membrane permeability, possibly as a consequence of the opening of Ca2+ channels being involved in Golgi-vesicle mediated exocytosis. Expand

TLDR
Wound healing in internodal cells of the freshwater algaNitella flexilis (Characeae) was studied in the light and electron microscope and the function of the coated vesicles and their interrelationship with other cell organelles is discussed. Expand

The significance of Ca2+ in the morphogenesis of Micrasterias studied with EGTA, verapamil, LaCl3 and calcium ionophore A 23187
TLDR
The hypothesis that Ca2+ influx through the plasma membrane affects and guides, during cell growth and development, the fusion of dictyosome vesicles, containing cell wall material, with the plasma margin supports the hypothesis that the streaming is supported by actin microfilaments. Expand
Cytoplasmic free calcium in Riccia fluitans L. and Zea mays L.: Interaction of Ca2+ and pH?
TLDR
It is concluded that regulation of cytoplasmic pH and free Ca2+ are interrelated and double-barrelled microelectrodes are useful tools for investigations of intracellular ion activities in plant cells. Expand
Disoriented growth of pollen tubes of Lilium longiflorum Thunb. induced by prolonged treatment with the calcium-chelating antibiotic, chlorotetracycline
TLDR
The disoriented growth is interpreted as an effect of the ability of CTC to chelate intracellular calcium ions, to bind them to membranes, and thus to disturb the dynamics of the delicate Ca2+-equilibria thought to regulate oriented exocytosis. Expand

SummaryMicrasterias denticulata was treated for 1–12 hours with 10−4 M CTC, a fluorescent indicator for membrane-bound Ca2+. The effects were investigated by light and electron microscopy. TheExpand
Induced net Ca2+ uptake and callose biosynthesis in suspension-cultured plant cells
TLDR
The data support the hypothesis that addition of the various substances might indirectly lead to membrane perturbation causing the common event of an increase in net Ca2+ uptake which results in callose deposition by a direct activition of the Ca2-dependent and plasma-membane-located 1,3-β-glucan synthase.

PINOCYTOSIS IN ROOT CAP CELLS EXPOSED TO URANYL SALTS
TLDR
Serial sections indicated that most vesicular structures with thickened membranes were in contact with the cell wall, but a few, including some which contained uranyl crystals, were within the protoplast, providing evidence of pinocytotic activity in intact plant cells exposed to a toxic heavy metal.
