Acclimation temperature affects thermal reaction norms for energy reserves in Drosophila

open access: yesScientific Reports, 2020
Organisms have evolved various physiological mechanisms to cope with unfavourable environmental conditions. The ability to tolerate non-optimal thermal conditions can be substantially improved by acclimation.

Assessment of Gene Expression Pattern of Rubisco and some physiological characteristics under Cold Stress Condition in Chickpea [PDF]

open access: yesمجله بیوتکنولوژی کشاورزی, 2013
Plant responses to low temperatures have been created through cold acclimation process using gene expression regulatory mechanisms. In this research, the quantitative gene expression ratio of rubisco, as an important enzyme participating in ...

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

Extensive Acclimation in Ectotherms Conceals Interspecific Variation in Thermal Tolerance Limits.

open access: yesPLoS ONE, 2016
Species' tolerance limits determine their capacity to tolerate climatic extremes and limit their potential distributions. Interspecific variation in thermal tolerances is often proposed to indicate climatic vulnerability and is, therefore, the subject of

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.

Effect of Meristem Size and Scion Origin on Micrografting of some Sweet Cherry Cultivars in vitro [PDF]

open access: yesMajallah-i ̒Ulum-i Bāghbānī, 2023
Introduction Sweet Cherry (Prunus avium) belongs to the Rosaceae family, which due to vegetative propagation problems, in vitro propagation is recommended to increase mass and disease-free production.

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.

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
