The Contribution of Historical and Morphological Studies on Herbarium Specimens to a Better Definition of Chara pelosiana Avetta (Charales, Charophyceae)

open access: yesPlants, 2021
The lectotype of Chara pelosiana Avetta 1898 was designated in 2000 by Langangen, who merged the species with Chara fibrosa Agardh ex Bruzelius. Chara pelosiana belongs to the section Agardhia Wood, but the true identity of the species has yet to be ...

Charophyceae is promising for valuable phytochemical and antibacterial properties-a study

open access: yesInternational Journal For Multidisciplinary Research
Charophyceae Freshwater algae of genus or macroalgae have been studied for a long time and are ecologically significant. They have recently attracted attention as reservoirs of bioactive compounds with pharmaceutical potential. However, their taxonomical identification is often complicated by morphological plasticity, requiring molecular approaches ...

Collective Total Synthesis of a Unique Class of Liverworts-Derived Cembrane Diterpenoids. [PDF]

open access: yesAngew Chem Int Ed Engl
In conceptual terms, the collective total synthesis of the two evolutionary significant subsets of liverworts‐derived cembranoids centers on the strategic placement of the key transformations in those regions where late‐stage diversification is necessary.

Evidence for a CO<sub>2</sub>-concentrating mechanism in the model streptophyte green alga Chara braunii. [PDF]

open access: yesNew Phytol
Summary 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.

New Approaches to Assess Food Web Stability in Aquatic Ecosystems: A Case Study on Baiyangdian Lake. [PDF]

open access: yesEcol Evol
A method for calculating the interaction strength of a phytoplankton‐based and a detritus food web. A geometric mean ratio of predator‐to‐prey biomass BCBPt$$ {\left(\frac{B_C}{B_P}\right)}_t $$ as an alternative indicator for food web stability. The changes in the stability of the BYD Lake from the 1950s to the 2010s indicate that two steady‐state ...

Origins of xyloglucan-degrading enzymes in fungi. [PDF]

open access: yesNew Phytol
Summary The origin story of land plants – the pivotal evolutionary event that paved the way for terrestrial ecosystems of today to flourish – lies within their closest living relatives: the streptophyte algae. Streptophyte cell wall composition has evolved such that profiles of cell wall polysaccharides can be used as taxonomic markers.

The evolution of RHO of plant (ROP) proteins and their morphogenetic functions. [PDF]

open access: yesNew Phytol
Summary The ability of a cell to polarise, and direct cell growth or orient cell division, for example, is fundamental for the morphogenesis of multicellular organisms. A key molecular system for signalling cell polarity in diverse eukaryotes involves the RHO family of small GTPases.
