Action Potential in Charophytes
2007The plant action potential (AP) has been studied for more than half a century. The experimental system was provided mainly by the large charophyte cells, which allowed insertion of early large electrodes, manipulation of cell compartments, and inside and outside media.

Quantization of a flux ratio in charophytes?
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1971Abstract 1. 1. The ratio of the Cl− influx into the vacuole to the Cl− influx into the whole cell has been measured for a large number of internodal cells of Chara corallina. The distribution of the values of this ratio shows no tendency to cluster about preferred values in integer ratios with each other. 2. 2. The claim of MacRobbie 1, that

CONSPECIFICITY OF SOME CHAROPHYTES1
Journal of Phycology, 1967SUMMARY Sweets Lake, British Columbia, is the type locality for plants originally described as Chara buckellii. Plants from this locality liave been crossed successfully to a second clone from Laguna La Drava, Argentina, the type locality for Nitellopsis bulbillifern.

Calcification of the Charophyte Oosporangium
1991The oosporangium is a unique and complex structure consisting of a central reproductive cell (the oospore) surrounded by vegetative cells. In the subfamily Chareae, six vegetative ensheathing cells (i.e. five spiral cells and one basal cell), completely surround the oospore and are in intimate contact with it.

New insights into Paleozoic charophyte morphology and phylogeny
American Journal of Botany, 2005Examination of Paleozoic charophyte fructifications using microscopy and high‐resolution x‐ray synchrotron microtomography has revealed that most of them have a utricle that forms a supplementary calcified cover around the gyrogonite. All Paleozoic families with utricles have been assigned to the Sycidiales.

Origin of plant auxin biosynthesis in charophyte algae
Trends in Plant Science, 2014The TRYPTOPHAN AMINOTRANSFERASE OF ARABIDOPSIS (TAA)/YUCCA flavin monooxygenase (YUC) pathway is the main auxin biosynthesis pathway in plants [1]. The origin of plant auxin biosynthesis remains unclear and controversial. Recently Yue et al. addressed this issue by performing phylogenetic analysis of TAA and YUC proteins [2]. They found that land plant

Microalgal and cyanobacterial assemblages on charophytes: a metacommunity perspective
Fundamental and Applied Limnology, 2017Despite all of the studies that have been carried out on angiosperm macrophytes, it is still unknown beyond any doubt whether charophytes affect periphyton composition. From the viewpoint of aquatic community organization, we must not only answer this question but must also evaluate the importance of this source of periphyton to the seston.

pH Banding in Charophyte Algae
2012The internodal cells of Characean algal species have long served as a model for membrane processes in plants, because their large size (up to several centimetres in length), simple geometry (cylinder) and clear separation from other cells in the plant have allowed experimental techniques such as multielectrode electrophysiological techniques and cell ...
