Indirect Export of Reducing Equivalents From the Chloroplast to Resupply NADP for C3 Photosynthesis—Growing Importance for Stromal NAD(H)?

open access: yesFrontiers in Plant Science, 2021
Plant productivity greatly relies on a flawless concerted function of the two photosystems (PS) in the chloroplast thylakoid membrane. While damage to PSII can be rapidly resolved, PSI repair is complex and time-consuming. A major threat to PSI integrity

Differential Gene Expression in Liver, Gill, and Olfactory Rosettes of Coho Salmon (Oncorhynchus kisutch) After Acclimation to Salinity. [PDF]

open access: yes, 2015
Most Pacific salmonids undergo smoltification and transition from freshwater to saltwater, making various adjustments in metabolism, catabolism, osmotic, and ion regulation. The molecular mechanisms underlying this transition are largely unknown.

Plasticity of Performance Curves in Ectotherms: Individual Variation Modulates Population Responses to Environmental Change

open access: yesFrontiers in Physiology, 2021
Many ectothermic animals can respond to changes in their environment by altering the sensitivities of physiological rates, given sufficient time to do so.

Resistance to frost and tuber soft rot in near-pentaploid Solanum tuberosum - S. commersonii hybrids [PDF]

open access: yes, 2007
The objectives of the present study were to evaluate the tolerance to low temperatures and tuber soft rot in sexual near-pentaploid hybrids between incongruent 2x (1EBN) Solanum commersonii (CMM) and 4x (4EBN) S. tuberosum (TBR). For freezing resistance,

Heat and Hypoxic Acclimation Increase Monocyte Heat Shock Protein 72 but Do Not Attenuate Inflammation following Hypoxic Exercise

open access: yesFrontiers in Physiology, 2017
Acclimation to heat or hypoxic stress activates the heat shock response and accumulation of cytoprotective heat shock proteins (HSPs). By inhibiting the NF-κB pathway HSP72 can preserve epithelial function and reduce systemic inflammation.

Foliar Application of Polyamines Modulates Winter Oilseed Rape Responses to Increasing Cold

open access: yesPlants, 2020
Cold stress is one of the most common abiotic stresses experienced by plants and is caused by low temperature extremes and variations. Polyamines (PAs) have been reported to contribute in abiotic stress defense processes in plants.

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.
