Evolutionary Conserved and Divergent Responses to Copper Zinc Superoxide Dismutase Inhibition in Plants

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT After an initial evolution in a reducing environment, life got successively challenged by reactive oxygen species (ROS), especially during the great oxidation event (GOE) that followed the development of photosynthesis. Therefore, ROS are deeply intertwined into the physiological, morphological and transcriptional responses of most present‐day

Plants synthesize ergothioneine, showing a link to abiotic stress

open access: yesPlant 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.

Vegetation trajectories over 150 years of temporary ponds created in the Camargue delta (Southern France)

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Temporary ponds in the Mediterranean climate have a high conservation value, but many have been severely destroyed or degraded. Pond restoration and new pond creation have been engaged widely. Evaluations of the success of such operations are generally carried out over 10–15 years and show divergent results over this timeframe. In

Extended envelopes around Galactic Cepheids III. Y Oph and alpha Per from near-infrared interferometry with CHARA/FLUOR

open access: yes, 2007
Unbiased angular diameter measurements are required for accurate distances to Cepheids using the interferometric Baade Wesselink method (IBWM). The precision of this technique is currently limited by interferometric measurements at the 1.5% level.
