Transmission electron microscopy characterisation of Spirulina bioplastics

Journal of Microscopy, EarlyView.
Abstract Plastic pollution is impacting global ecosystem health. Bioplastics made from unprocessed biomass, including whole or fragmented tissues, are one potential solution. They are biodegradable and exhibit competitive mechanical performance. Seaweed and microalgae have gained popularity over the last decade as bioplastic feedstocks due to their ...

Epitypification of Merismopedia tranquilla (Cyanobacteria) prompts phylogenetic reassessment of the genus and the description of two morphologically similar genera

Journal of Phycology, EarlyView.
Abstract The genus Merismopedia is morphologically characterized by its distinctive colony arrangement yet exhibits considerable variability among species. Recent studies suggested that Merismopedia is polyphyletic, and its most likely true lineage was provisionally placed within the Microcystaceae. However, the available molecular data for most of the

DnaK3 Is Involved in Biogenesis and/or Maintenance of Thylakoid Membrane Protein Complexes in the Cyanobacterium Synechocystis sp. PCC 6803

Life, 2020
DnaK3, a highly conserved cyanobacterial chaperone of the Hsp70 family, binds to cyanobacterial thylakoid membranes, and an involvement of DnaK3 in the biogenesis of thylakoid membranes has been suggested. As shown here, light triggers synthesis of DnaK3

Thermoluminescence in Chloroplast Thylakoid [PDF]

, 2012
Luminescence occurs in almost all the materials absorbing photon energy and is a phenomenon of light emitting process. There are various types of luminescence, e.g. fluorescence, phosphorescence, delayed luminescence, chemiluminescence and thermoluminescence.

Ecophysiological study of green microalgae isolated from the grit crust of the Atacama Desert

Journal of Phycology, EarlyView.
Abstract Terrestrial algae play a critical, yet often overlooked, role in the functioning of biological soil crusts (biocrusts), which are considered microecosystems, particularly in extreme environments. This study investigated the ecophysiological traits of green algae isolated from the grit crust—a unique biocrust type reported a few years ago in ...

Heat‐evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts

New Phytologist, EarlyView.
Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

Loss of qE Does Not Necessarily Lead to Photoinhibition: Sustained Non-Photochemical Quenching in the Absence of PsbS and Zeaxanthin. [PDF]

Plant Cell Environ
ABSTRACT Photosynthetic light‐harvesting complexes mediate light absorption and energy dissipation. By modulating the photosystems' absorption cross‐section, they affect both photosynthetic activity and non‐photochemical quenching (NPQ). These processes are often studied by spectrally integrated chlorophyll fluorescence, masking their associated ...
