Photosynthetic complex stoichiometry dynamics in higher plants: environmental acclimation and photosynthetic flux control

open access: yesFrontiers in Plant Science, 2014
The composition of the photosynthetic apparatus of higher plants is dynamically adjusted to long-term changes in environmental conditions such as growth light intensity and light quality, and to changing metabolic demands for ATP and NADPH imposed by ...

Cold Stress Response: An Overview in Chlamydomonas

open access: yesFrontiers in Plant Science, 2020
Low temperature (or cold) is one of the major environmental factors that limit the growth and development of many plants. Various plant species have evolved complex mechanisms to adjust to decreased temperature.

Campomanesia xanthocarpa (Myrtaceae: Myrtoideae) seedlings reveal morpho-physiological plasticity under shade conditions

open access: yesBrazilian Journal of Biology, 2023
Plants exposed to different light intensities generate physiological, morphological, and anatomical changes conducting to plasticity. Thus, this characteristic establishes the ability of plants to present phenotypic adjustments by the same genotype under

Thermal Acclimation: Effects on Populations and Communities

open access: yes, 2023
Thermal acclimation may be a greatly underappreciated phenomenon contributing to population and community dynamics. Commonly, models of populations or communities in variable thermal environments assume that organismal performance changes instantaneously

Truncated Hemoglobins 1 and 2 Are Implicated in the Modulation of Phosphorus Deficiency-Induced Nitric Oxide Levels in Chlamydomonas

open access: yesCells, 2019
Truncated hemoglobins (trHbs) form a widely distributed family of proteins found in archaea, bacteria, and eukaryotes. Accumulating evidence suggests that trHbs may be implicated in functions other than oxygen delivery, but these roles are largely ...

Photoprotective Acclimation of the Arabidopsis thaliana Leaf Proteome to Fluctuating Light

open access: yesFrontiers in Genetics, 2020
Plants are subjected to strong fluctuations in light intensity in their natural growth environment, caused both by unpredictable changes due to weather conditions and movement of clouds and upper canopy leaves and predictable changes during day-night ...

Tropical Trees Will Need to Acclimate to Rising Temperatures—But Can They?

open access: yesPlants, 2023
For tropical forests to survive anthropogenic global warming, trees will need to avoid rising temperatures through range shifts and “species migrations” or tolerate the newly emerging conditions through adaptation and/or acclimation.

Summary of acclimation scenarios.

open access: yes, 2023
We analyzed the transmission model (Eqs 1.1–1.4) under several acclimation scenarios (Eqs 2–4). These scenarios include various combinations of the time to host acclimation, ψH, the strength of beneficial acclimation, and whether the infection rate, η(T),

Hyperbaric intervention ameliorates the negative effects of long-term high-altitude exposure on cognitive control capacity

open access: yesFrontiers in Physiology
IntroductionHypoxia due to reduced partial pressure of oxygen from high-altitude exposure affects the cognitive function of high-altitude migrants. Executive function is an important component of human cognitive function, characterized by high oxygen ...
