Main conclusion Environmental-friendly techniques based on plant stress memory, cross-
stress tolerance, and seed priming help sustainable agriculture by mitigating negative …

The key role of cell walls in setting mesophyll conductance to CO2 (gm) and, consequently,
photosynthesis is reviewed. First, the theoretical properties of cell walls that can affect gm …

Conversion of sunlight into photochemistry depends on photoprotective processes that allow
safe use of sunlight over a broad range of environmental conditions. This review focuses on …

Aim Trade‐offs among tolerances to different abiotic stressors limit polytolerance in woody
plants. However, the general trait syndromes that underlie large‐scale tolerance patterns of …

In this work, we review the physiological and molecular mechanisms that allow vascular
plants to perform photosynthesis in extreme environments, such as deserts, polar and alpine …

In Antarctica, multiple stresses (low temperatures, drought and excessive irradiance)
hamper photosynthesis even in summer. We hypothesize that controlled inactivation of PSII …

Chlorophyll fluorescence can serve as a proxy of photosynthesis in boreal forests. When
sustained non-photochemical quenching (NPQ S) relaxes towards summer, leaf chlorophyll …

Background Plants have adapted to survive seasonal life-threatening frost and drought.
However, the timing and frequency of such events are impacted by climate change …

Resurrection plants are vascular species able to sustain extreme desiccation in their
vegetative tissues. Despite its potential interest, the role of leaf anatomy in CO2 diffusion and …

Chlorophylls and carotenoids are two families of antioxidants present in daily ingested
foods, whose recognition as added-value ingredients runs in parallel with the increasing …
