Desiccation induces accumulations of antheraxanthin and zeaxanthin in intertidal macro-alga Ulva pertusa (Chlorophyta). [PDF]
PLoS ONE, 2013 For plants and algae, exposure to high light levels is deleterious to their photosynthetic machineries. It also can accelerate water evaporation and thus potentially lead to drought stress.

An In Vivo Quantitative Comparison of Photoprotection in Arabidopsis Xanthophyll Mutants
Frontiers in Plant Science, 2016 Contribution of different LHCII antenna carotenoids to protective NPQ (pNPQ) were tested using a range of xanthophyll biosynthesis mutants of Arabidopsis: plants were either devoid of lutein (lut2), violaxanthin (npq2), or synthesized a single ...

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security
Journal of the Science of Food and Agriculture, EarlyView.Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Lactuca sativa L. losses and wastes as a source of biobased ingredients
Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND The growing global population and increasing consumer focus on healthy eating challenge the agricultural sector to ensure both sustainable food production and safety. Lettuce (Lactuca sativa Mill.), the most cultivated leafy vegetable worldwide, can lose up to 40% of its weight during processing.

Limnology and Oceanography: Methods, EarlyView.Abstract Imaging Pulse Amplitude Modulation (PAM) fluorometry allows spatially resolved measurements of Photosystem II (PSII) fluorescence kinetics through time without disturbing study organisms or their environments. In particular, the use of photosynthesis–irradiance curves (P–I curves) provides detailed information on PSII quantum efficiency ...

Diversity of winter photoinhibitory responses: a case study in co-occurring lichens, mosses, herbs and woody plants from subalpine environments [PDF]
, 2017 Winter evergreens living in mountainous areas have to withstand a harsh combination of high light levels and low temperatures in wintertime. In response, evergreens can activate a photoprotective process that consists of the downregulation of ...
