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 ...

Impact of Anthropogenic Activities and Climate Change on the Wetlands in the North-West of Madagascar. [PDF]

Plant Environ Interact
ABSTRACT Macrophytes are vulnerable to various factors in their natural ecosystems, including climatic, ecological, and anthropogenic changes. This study aims to document how these factors influence floristic composition. Four sites were investigated in the Boeny Region of northwest Madagascar: Ambatoboeny, Marovoay, Ankarafantsika National Park, and ...

Potassium extrusion by plant cells: evolution from an emergency valve to a driver of long-distance transport. [PDF]

New Phytol
Summary The ability to accumulate nutrients is a hallmark for living creatures and plants evolved highly effective nutrient transport systems, especially for the uptake of potassium (K+). However, plants also developed mechanisms that enable the rapid extrusion of K+ in combination with anions.

Circadian Oscillations in Branchlet Angle and Irradiance‐Dependent Acclimation in Chara braunii Under Continuous Light [PDF]

Plant Direct
ABSTRACT Endogenous biological rhythms are central to temporal organization in land plants, yet their evolutionary origins in streptophyte algae remain unresolved. We investigated whether rhythmic morpho‐physiological processes in Chara braunii are consistent with endogenous regulation and how continuous light intensity modulates these responses. In C.

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 ...

Rediscovering of Chara braunii (Characeae, Charophyta) in Madeira (Macaronesian region, Portugal) [PDF]

, 2021
Chara braunii C.C. Gmelin (Characeae, Charophyta) was found in Madeira Island (Portugal) in a water channel in an agricultural area. This constitutes the first record of that species since 1944 in the Macaronesian region (Azores, Madeira and Canary ...

A Comparative Analysis of Receptor-Like Kinases in Chlorophyta Reveals the Presence of Putative Cell Wall Integrity Sensors. [PDF]

Physiol Plant
ABSTRACT Receptor‐like kinases (RLKs) detect external and internal signals, triggering responses essential for growth and adaptation. Among internal cues, cell wall integrity (CWI) sensing plays a key role, as changes in cell wall structure activate responses critical for development and defense.

Die Armleuchteralgen (Characeae) Südtirols

, 2020
Stoneworts (Characeae) have never been the subject of a systematic survey in South Tyrol. While there was a certain interest in this group of plants in the 19th century, further study of this group of plants failed to take place for almost a whole ...
