Quantifying the efficiency of photoprotection [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2017
A novel emerging technology for the assessment of the photoprotective ‘power’ of non-photochemical fluorescence quenching (NPQ) has been reviewed and its insightful outcomes are explained using several examples. The principles of the method are described in detail as well as the work undertaken for its justification.

Photoprotection in 2012

, 2012
La photoprotection est essentielle dans la prévention du processus de photovieillissement et de la carcinogenèse cutanée. Elle peut être comportementale, naturelle, induite, vestimentaire, topique et systémique.

An alfalfa MYB71‐centered activation–attenuation module fine‐tunes redox homeostasis and drought tolerance in Medicago sativa

Journal of Integrative Plant Biology, EarlyView.
In alfalfa, the transcription factor MsMYB71 activates the peroxiredoxin Q gene MsPrxQ, which helps remove harmful reactive oxygen species and improves drought tolerance. The WD40‐repeat protein MsPRL1 and the Cullin‐family scaffold protein MsCUL4 interact with and limit MsMYB71 accumulation and activity in an activation‐attenuation mechanism ...

Ultrafast X-ray probe of nucleobase photoprotection

, 2012
We will present first results of a UV-pump X-ray-probe study of the photoprotection mechanism of thymine. The experiment used element specific Auger spectroscopy and was carried out at the LCLS.

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

MicroRNA 160 controls the auxin response factor–class III peroxidase module and couples salicylic acid and redox signaling networks in the potato hypersensitive response to potato virus Y

New Phytologist, EarlyView.
miR160 links salicylic acid, auxin, and redox signaling with the growth–defense trade‐off in the potato hypersensitive response to potato virus Y. Summary Hypersensitive response (HR) is an effector‐triggered immune response leading to pathogen restriction and local cell death.

Phosphatidylcholine acyl turnover facilitates thylakoid lipid remodeling and promotes plant survival under heat stress

New Phytologist, EarlyView.
Coordinated galactolipid–TAG conversion during heat stress–induced thylakoid lipid remodeling. Summary Heat stress destabilizes chloroplast membranes, requiring rapid lipid remodeling to maintain photosynthetic function. Although thylakoid lipid remodeling and triacylglycerol (TAG) accumulation are established heat responses, the role of ...

High‐Throughput Screen of NPQ in Sorghum Shows Highly Polygenic Architecture of Photoprotection

Plant-Environment Interactions
Natural genetic variation in photosynthesis and photoprotection within crop germplasm represents an untapped resource for crop improvement. Sorghum bicolor (sorghum) is one of the world's most widely grown crops, yet the genetic basis of photoprotection ...
