  • Membrane Potentials in Amoeba Proteus
    J. Exp. Biol. (1966), 45, 251-267 251 With 10 text-figures Printed in Great Britain MEMBRANE POTENTIALS IN AMOEBA PROTEUS BY M. S. BINGLEY R.A.F. Institute of Aviation Medicine, Farnborough, Hants. {Received 16 February 1966) INTRODUCTION The possibility that the initiation of pseudopods together with the direction of cytoplasmic streaming may be induced by local depolarization of the membrane has been advanced from time to time for many years past. But is it difficult to find a direct statement to this effect in the literature. Amici (1818) suggested an electrical theory to account for streaming in plant cells and more recently Kitching (1961) considers the possibility of depolarization of the cell surface initiating contraction. When he discussed Hahnert's work (Hahnert, 1932) on the response of amoebae to electricity he pointed out that movement of the pseudopods towards the cathode may be an enhancement of 'local currents associated with local excitation'. It is one thing to put forward a hypothesis but another to obtain convincing measurements which are free from the suspicion of doubt and artifact. Membrane potentials were first seriously measured in Amoeba proteus by Telkes in 1931. Using large electrodes, she obtained low values of membrane potential but produced extremely valuable information on various depolarizing agents such as potassium and sodium chloride. Buchtal & Peterfi (1936) obtained low values of potential for A. proteus. Wolfson (1943) produced convincing values for membrane potential in Chaos chaos and, using electrodes of large diameter, he obtained potentials as high as workers using more modern micro- electrodes. More recently Riddle (1962) working on PeUomyxa caroHnensis recorded values of — 90 mV.

  • Cytoplasmic Streaming and Microtubules in the Coenocytic Marine Alga, Caulerpa Prolifera
    J. Cell Sci. 2, 465-472 (1967) 465 Printed in Great Britain CYTOPLASMIC STREAMING AND MICROTUBULES IN THE COENOCYTIC MARINE ALGA, CAULERPA PROLIFERA D. D. SABNIS AND W. P. JACOBS Biology Department, Princeton University, Princeton, N.J., U.S.A. SUMMARY Two distinct patterns of cytoplasmic streaming in the leaf of Caulerpa prolifera are described. Broad, longitudinally running, two-way streams are restricted to the endoplasm of one leaf surface. Also present are large numbers of narrow, two-way streams that coil helically through- out the endoplasm surrounding the central vacuole. Numerous unique bundles of aggregated, evenly spaced, oriented microtubules are distributed within the inner cytoplasm some distance from the cell wall. Cortical microtubules, as described for other plant material, have been only very infrequently encountered in Caulerpa and appear to be sparsely distributed. Apart from the prominent bundles of oriented microtubules, no other significant ultrastructural differences were noted between the stationary ectoplasm and streaming endoplasm. The possible cyto- skeletal role of the oriented microtubules in the development and maintenance of asymmetries in organ differentiation is discussed in relation to their direct or indirect influence on the directional migration of cytoplasmic components. INTRODUCTION Although there have been numerous reports of the occurrence of microtubular and microfibrillar elements in the cytoplasm of a variety of cell types, only a limited number of publications has described these structures in algal cells (Berkaloff, 1966; Nagai & Rebhun, 1966). The possible functions of cytoplasmic microtubules and microfilaments in the plant cell have been the subjects of some considerable con- jecture and controversy. Microtubules have been considered to play a role in the laying down of secondary walls in differentiating tissue (Wooding & Northcote, 1964), and cell-plate formation in dividing cells (Pickett-Heaps & Northcote, 1966).

  • Differential Organelle Movement on the Actin Cytoskeleton in Lily Pollen Tubes
    Cell Motility and the Cytoskeleton (2007) Differential Organelle Movement on the Actin Cytoskeleton in Lily Pollen Tubes Alenka Lovy-Wheeler,1 Luis Ca´rdenas,2 Joseph G. Kunkel,1 and Peter K. Hepler1* 1Department of Biology and Plant Biology Graduate Program, Morrill Science Center III, University of Massachusetts, Amherst, Massachusetts 2Departamento de Biologı´a Molecular de Plantas, Instituto de Biotechnologı´a, Cuernavaca, Morelos, Me´xico We have examined the arrangement and movement of three major compart- ments, the endoplasmic reticulum (ER), mitochondria, and the vacuole during oscillatory, polarized growth in lily pollen tubes. These movements are de- pendent on the actin cytoskeleton, because they are strongly perturbed by the anti-microfilament drug, latrunculin-B, and unaffected by the anti-microtubule agent, oryzalin. The ER, which has been labeled with mGFP5-HDEL or cyto- chalasin D tetramethylrhodamine, displays an oscillatory motion in the pollen tube apex. First it moves apically in the cortical region, presumably along the cortical actin fringe, and then periodically folds inward creating a platform that transects the apical domain in a plate-like structure. Finally, the ER reverses its direction and moves basipetally through the central core of the pollen tube. When subjected to cross-correlation analysis, the formation of the platform precedes maximal growth rates by an average of 3 s (35–408). Mitochondria, labeled with Mitotracker Green, are enriched in the subapical region, and their movement closely resembles that of the ER. The vacuole, labeled with car- boxy-dichlorofluorescein diacetate, consists of thin tubules arranged longitudi- nally in a reticulate network, which undergoes active motion.

Summary that synthetic lipid (DOPG) vesicles and ‘stealth’ vesicles with PEG phospholipids moved in the cytoplasm. Plant cells show myosin-driven organelle movement, called cytoplasmicstreaming.Solublemolecules,suchasmetabolites do not move with motor proteins but by diffusion. However, is all of this streaming active motor-driven organelle transport? Introduction Our recent simulation study (Houtman et al., 2007) shows The cytoplasm of eukaryotic cells consists of all cell material that active transport of organelles gives rise to a drag in the between the nucleus and the plasma membrane and cytosol, setting up a hydrodynamic flow, which contributes to contains membrane-bounded structures, organelles, which a fast distribution of proteins and nutrients in plant cells. Here, are embedded in the cytosol consisting of water, salts and we show experimentally that actively transported organelles organic molecules, including sugars, proteins and many produce hydrodynamic flow that significantly contributes to enzymes that catalyze reactions.

The high indicator value of charophytes toward eutrophication results in their wide use in the bioassessment systems. I explored the variability of stonewort communities’ requirements for trophic conditions in lowland temperate lakes and attempted to determine the role of individual syntaxa in assessing the ecological status of lakes in Poland. The position of charophyte communities’ niches along the trophic gradient was analysed using the Outlying Mean Index approach. A few stonewort communities, i.e., Nitelletum opacae, N. mucronatae, N. flexilis and Charetum filiformis appeared to be specialised concerning water quality and may be considered indicators of habitats less eutrophic than the “mean” trophic conditions in the study domain. Most stonewort communities were relatively common in European waters. Four of them, i.e., Charetum tomentosae, C. asperae, C. contrariae and Nitellopsidetum obtusae, can be classified as ‘generalists’ with low marginality and broad ecological tolerance. Most stonewort communities appeared in a broad range of ecological status classes. In the case of 15 communities, 6 to 25% of occurrences were observed in lakes representing a less than good status, and they cannot be considered indicative of good ecological conditions.

  • The Worldwide Range of the Charophyte Species Native to Germany
    Rostock. Meeresbiolog. Beitr. Heft 28 45-96 Rostock 2018 Heiko KORSCH* * Schillbachstraße 19, 07743 Jena [email protected] The worldwide range of the Charophyte species native to Germany Abstract Based on extensive evaluations, the worldwide distributions of the 36 Charophyte species native to Germany are presented. Some of these species are distributed almost worldwide (e.g. Chara braunii, C. vulgaris, Nitella hyalina), while others have much smaller ranges. Chara filiformis for example is restricted to a small part of continental Europe. For many species comments are made to explain the species concept used or to give hints about doubtful data. Keywords: Plant geography, Characeae, Charophytes, range-maps, Chara, Lamprothamnium, Lychnothamnus, Nitella, Nitellopsis, Tolypella Zusammenfassung: Areale der in Deutschland heimischen Characeen-Arten. Auf der Grundlage umfangreicher Recherchen werden die weltweiten Areale der in Deutschland vorkommenden 36 Characeen-Arten dargestellt. Von diesen Arten sind einige (z. B. Chara braunii, C. vulgaris, Nitella hyalina) fast weltweit verbreitet, andere haben deutlich kleinere Areale. So ist z. B. Chara filiformis auf kleine Teile Europas beschränkt. Zu einer ganzen Reihe von Arten werden Kommentare geben. Diese erläutern die verwendeten Artumgrenzungen oder geben Hinweise zu fraglichen Angaben. 1 Introduction In recent decades and after a phase of stagnation in Germany, interest in the Characeae has markedly increased. The Habitats Directive 92/43/EC (EC1992) and the Water Framework Directive 2000/60/EC (EC 2000) of the European Union have intensified this process. Because of their size and their complex structure, the Charophytes are morphologically clearly distinguished from most other groups of Algae. The results of genetic investigations show that they are more closely related to the Mosses and higher plants rather than to the other algae (QUI 2008).

The efforts of the principal investigator in carrying out the aims and objectives of this study of the Characeae were greatly enhanced and strengthened by the generous contributions of time, labor and guidance expended by quite a long list of individuals. The project was very fortunate in securing the part-time services of a competent cytologist in the person of my wife, who gave invaluable aid without pay, in the laborious task of preparing and analyzing chromosome counts in the home lab and on trips to the field. Mr. Donald Tindall (graduate student) in July, 1960, began research on the Characeae with particular emphasis on the ecology and the complete life history (including cytology) of Nitella flexilis in Doe Run, Kentucky.

The results of the research also include data regarding the species composition and present state of Nitella. The dominant species of Nitella is Nitella opaca, which is characterized by a specific distribution, morphological variability and ecology. The present state ofNitella is not steady, especially in the watershed of the lake, since in this area there are some permanent changes in the hydrology of the terrain. Therefore, there is a need to establish long-term and complex monitoring which will result in the prompt detection of risk factors and influences, thereby enabling a rapid reaction to a possible newly emerged negative state. Key words: Lake Ohrid, Nitella, distribution, morphological variability, ecology, present state INTRodUctioN 10500 tons (Trajanovska, 2002; Trajanovska et al., 2004). Lake Ohrid is a unique natural ecosystem of Tertiary age and oligotrophic character, which is character- The Charophyta algae in Lake Ohrid and its sur- ized by a high level of biodiversity and endemism.
