Allelopathic effect of Ulva intestinalis L. on the Baltic filamentous cyanobacterium Nostoc sp.

Annales Universitatis Paedagogicae Cracoviensis Studia Naturae, 2018
Allelopathy is a prevalent natural phenomenon in aquatic ecosystem. We reported the effects of the green macroalga Ulva intestinalis L. collected from estuaries of the Baltic Sea (Poland) on the growth and chlorophyll fluorescence of common filamentous ...

The Mechanisms of Codon Reassignments in Mitochondrial Genetic Codes [PDF]

, 2007
Many cases of non-standard genetic codes are known in mitochondrial genomes. We carry out analysis of phylogeny and codon usage of organisms for which the complete mitochondrial genome is available, and we determine the most likely mechanism for codon ...

Improving Whole Biodiversity Monitoring and Discovery With Environmental DNA Metagenomics

Molecular Ecology Resources, EarlyView.
ABSTRACT Environmental DNA (eDNA) metagenomics sequences all DNA molecules present in environmental samples and has the potential of identifying virtually any organism from which they are derived. However, due to unacceptable levels of false positives and negatives, this approach is underexplored as a tool for biodiversity monitoring across the tree of

A systematic review of marine macroalgal degradation: Toward a better understanding of macroalgal carbon sequestration potential

Journal of Phycology, EarlyView.
Abstract Although macroalgae are gaining recognition for their potential role in marine carbon sequestration, critical knowledge gaps related to the fate of macroalgal carbon limit our capacity to quantify rates of macroalgal carbon sequestration.

Phylotranscriptomics unveil a Paleoproterozoic-Mesoproterozoic origin and deep relationships of the Viridiplantae

Nature Communications, 2023
The Viridiplantae comprise two main clades, the Chlorophyta (including a diverse array of marine and freshwater green algae) and the Streptophyta (consisting of the freshwater charophytes and the land plants).

Subtidal algal community structure in kelp beds around the Cape Peninsula (Western Cape, South Africa) [PDF]

, 2000
The subtidal understorey seaweed communities were studied along a coastal distance of 104 km around the Cape Peninsula, which is situated in an overlap region between two marine provinces and characterized by a considerable temperature gradient. Sampling

Occurrence and toxicity of Microcystis aeruginosa (Cyanobacteria) in the Paraná River, downstream of the Yacyretá dam (Argentina) [PDF]

, 2016
Cyanobacteria constitute the main toxin producers in inland water ecosystems and have extensive global distribution. The presence of hepatotoxins in aquatic environments is hazardous to human and animal health; even though the presence and identification

Evolutionary‐conserved RLF, a cytochrome b5‐like heme‐binding protein, regulates organ development in Marchantia polymorpha

New Phytologist, EarlyView.
Summary In Arabidopsis thaliana, REDUCED LATERAL ROOT FORMATION (RLF), a cytochrome b5‐like heme‐binding domain (Cytb5‐HBD) protein, is necessary for proper lateral root (LR) formation. Whereas the other Cytb5‐HBD proteins in A. thaliana regulate different metabolic reactions, RLF is unique as it specifically regulates organ development.
