Plants synthesize ergothioneine, showing a link to abiotic stress

Plant Biology, EarlyView.
Various plants possess ergothioneine biosynthetic genes and can synthesize this antioxidant, where increased EGT levels under abiotic stress conditions indicate protective functions. Abstract Ergothioneine (EGT) is a sulphur‐containing histidine derivative and a potent antioxidant that exhibits beneficial effects on human health.

Insertional Mutagenesis of Chlamydomonas reinhardtii

Bio-Protocol, 2015
The unicellular microalga Chlamydomonas reinhardtii (C. reinhardtii) has been used as a reference model for numerous fields of research. Principle research areas are eukaryotic flagellar structure and function, basal bodies (centrioles), cell-cell ...

The unicellular green microalga Botryosphaerella sudetica links plant‐like light protection with an algal lifestyle

New Phytologist, Volume 251, Issue 1, Page 372-383, July 2026.
Summary Nonphotochemical quenching (NPQ) mechanisms fine‐tune light utilisation in the photosynthetic antenna, for example, in response to excess light, to prevent photodamage. NPQ comprises distinct mechanisms, all contributing to photoprotection but acting on different time scales.

An N‐acetyltransferase‐MAPK fusion protein modulates developmental reprogramming in Physcomitrium patens

New Phytologist, Volume 251, Issue 1, Page 321-339, July 2026.
Summary We discovered a previously uncharacterized moss‐specific protein, Rosetta NATD‐MAPK 1 (RAK1) in Physcomitrium patens, which uniquely integrates MAP kinase (MAPK)‐dependent signaling with N‐acetyltransferase activity. Through phenotypical and biochemical analyses, we characterized RAK1 function in the regulation of the 2D‐to‐3D growth transition.

Two‐Dimensional Infrared Spectroscopy Reveals the Presence of a Bridging CO Ligand in Two Catalytic Intermediates of [FeFe] Hydrogenase

Angewandte Chemie, Volume 138, Issue 21, 18 May 2026.
Two‐dimensional (2D) infrared (IR) spectroscopy provides vastly more structural and functional insight into chemical and biological systems than linear IR spectroscopy. Here, we apply 2D‐IR spectroscopy to two controversially discussed states of the [FeFe] hydrogenase active site, revealing the presence of a bridging carbonyl ligand, which is difficult

Investigations of Chlamydomonas reinhardtii ergosterol biosynthesis

, 2009
Ergosterol is the major sterol found in the membranes of Chlamydomonas reinhardtii. While past studies have identified some ergosterol mutants in C. reinhardtii, very little is known about sterol biosynthesis pathways in this species.

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

Molecular Oncology, Volume 20, Issue 6, Page 1591-1611, June 2026.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Evaluation of the phenol degradation capacity of microalgae-bacteria consortia from the bay of Cartagena, Colombia

TecnoLógicas, 2019
The development of new technologies for environmental reparation has allowed the application of inexpensive alternatives such as bioremediation, which has a high potential to treat ecosystems polluted with hydrocarbons. Microalgae-bacteria consortia have
