Sphaerochara canadensis (Charophyceae): A circumpolar species with a high temperature optimum. [PDF]

J Phycol
Abstract Sphaerochara canadensis, an aquatic macrophyte belonging to the Characeae, is described as a species with a circumpolar distribution and occurs in the polar (to boreal) zonobiomes, suggesting that it is cold‐stenothermic. A recent report of an occurrence in Lake Wolfgangsee, Austria, contradicted this assumption, prompting this study to ...

Tracing Aquatic Macrophyte Development in Nansi Lake, Northern China's Largest Freshwater Lake: Plant Macrofossils From 1855 to Present. [PDF]

Ecol Evol
This study presents a detailed plant macrofossil record of a floodplain lake in the lower Yellow River (Huanghe River) Basin, which has undergone significant channel modifications and catastrophic floods. The lake also serves as an impoundment along China's Eastern Route of the South‐to‐North Water Diversion Project. The results cover time periods from

Optimized Laboratory Maintenance and Functional Testing of Chara braunii. [PDF]

Curr Protoc
Abstract Chara braunii is an emerging model species for studying plant evolution and development. Various members of the Chara genus have been used for pioneering studies of electrophysiology, cytoplasmic streaming, and cell biology. However, many studies have been limited by challenges, such as overgrowth with epiphytes or non‐continuous growth ...

The role of indole-3-acetic acid and characterization of PIN transporters in complex streptophyte alga Chara braunii. [PDF]

New Phytol
Summary Auxin, indole‐3‐acetic acid (IAA), is a key phytohormone with diverse morphogenic roles in land plants, but its function and transport mechanisms in algae remain poorly understood. We therefore aimed to explore the role of IAA in a complex, streptophyte algae Chara braunii. Here, we described novel responses of C.

Checklist, Red List, and Distribution Pattern of Charophytes (Charophyceae, Charales) in Slovakia Based on Critical Revision of Herbarium Specimens

Diversity, 2022
A critical revision of charophytes collected in Slovakia from 1887 up to present, based on herbaria specimens, provided us with the opportunity to compile an updated checklist and to revaluate their threat status in order to obtain the current red list ...

POSITIVE VARIATIONS IN NITELLA [PDF]

Journal of General Physiology, 1935
The reversible electrical variations hitherto described for plants and animals consist in a reversible loss of positive potential at a stimulated spot by which it becomes more negative. In this paper we describe changes which consist in a reversible loss of negative potential at a stimulated spot whereby it becomes more positive.

Using Morphology and Genomic Template Stability (GTS) to Track Herbicide Effect on Some Submersed Aquatic Plants

Applied Environmental Research, 2016
This study aimed to detect the genotoxic effects of glyphosate on aquatic plants by the RAPD-PCR technique. Native aquatic plants were screened for herbicide testing.

THE CONCENTRATION EFFECT IN NITELLA [PDF]

Journal of General Physiology, 1929
A method distinguishing between the concentration effect due to the cell wall and that due to the protoplasm is described: the importance of this lies in the fact that if the protoplasm shows a concentration effect one or both ions of the salt must tend to enter its outer surface.
