Journal of General Physiology, 1935 Many forms of irregular rhythm and of partial block occurring in the vertebrate heart can be duplicated in Nitella. In order to observe these phenomena the cells of Nitella are kept for 6 weeks or more in a nutrient solution. They are then exposed for 3 hours or less to 0.01 M NaCl, NaSCN, or guanidine chloride, which reduce the time ...

Environmental predictors of charophytes in a subtropical reservoir
Acta Limnologica Brasiliensia, 2020 : Aim In this study we check whether three simple environmental factors are good predictors of charophytes occurrence. Methods The Characeae material was sampled two times a year during the years of 2001, 2002 and 2003, over 235 sites distributed along

ON THE ACCUMULATION OF DYE IN NITELLA [PDF]
Journal of General Physiology, 1925 Living cells of Nitella were placed in different concentrations of brilliant cresyl blue solutions at pH 6.9. It was found that the greater the concentration of the external dye solution, the greater was the speed of accumulation of the dye in the cell sap and higher was the concentration of dye found in the sap at equilibrium.

Biomass generation and biodiesel production from macroalgae grown in the irrigation canal wastewater
Water Science and Technology, 2021 The wastewater concentration is commonly acceptable for macroalgae growth; this process consumes water and is applicable for bioremediation. This study evaluated biodiesel's potential production from freshwater macroalga, Nitella sp., using batch ...

STIMULATION BY COLD IN NITELLA [PDF]
Journal of General Physiology, 1935 Sudden local chilling causes action currents to be set up in Nitella and in Chara, an effect which does not follow gradual local chilling. This may be due to a partial solidification of the non-aqueous protoplasmic surfaces which makes them susceptible to rupture by the protoplasmic streaming.

Evidence for a CO<sub>2</sub>-concentrating mechanism in the model streptophyte green alga Chara braunii. [PDF]
New PhytolSummary Oxygenic photosynthesis in streptophytic algae, such as Charophyceae, is often impeded by low CO2 levels in aquatic habitats. Consequently, many algal groups evolved a CO2‐concentrating mechanism (CCM). However, its presence in Charophyceae remains controversial.

Italian Volcanic lakes: a diversity hotspot and refuge for European charophytes
Journal of Limnology, 2014 Macrophytes are one of the most important components of primary producers in lacustrine environments. Charophytes represent the most threatened group of macrophytes and are included in many European Red-Lists.
