Some Mechanisms of Damage and Acclimation of the Photosynthetic Apparatus Due to High Temperature *
نویسنده
چکیده
A review is made of recent publications concerning the mechanisms of damage and acclimation of the photosynthetic apparatus due to high temperature. Under stress the organisms undergo first of all destabilisation followed by normalisation and stability, when limit of tolerance are not exceeded and the adaptive capacity is not overtaxed. The influence of heat stress on PSII and PSI activity, lipid composition, protein content, CO2 assimilation and antioxidant enzymes has been described. Besides the processes leading to plant acclimation to high temperature were discussed.

Intraspecific variation in thermal acclimation of photosynthesis across a range of temperatures in a perennial crop
Interest in the thermal acclimation of photosynthesis has been stimulated by the increasing relevance of climate change. However, little is known about intra-specific variations in thermal acclimation and its potential for breeding. In this article, we examined the difference in thermal acclimation between alfalfa (Medicago sativa) cultivars originating from contrasting origins, and sought to a...
متن کاملDifferential freezing resistance and photoprotection in C3 and C4 eudicots and grasses
Globally, C4 plants dominate hot, open environments, but this general pattern is underpinned by important differences in the biogeography of C4 lineages. In particular, the species richness of C4 Poaceae (grasses) increases strongly with increasing temperature, whereas that of the major C4 eudicot group Chenopodiaceae correlates positively with aridity. Freezing tolerance is a crucial determina...

The present experiment was aimed to evaluate the freezing tolerance of two cold tolerant (MCC426 and MCC252) and a cold susceptible (MCC505) chickpea genotypes. The study was carried out in a split-plot factorial design with three replications. Factorial arrangement of genotype and acclimation (acclimation and non acclimation) were imposed as main plot and temperatures (0, -4, -8, -12, 16, -20º...
متن کاملPhotosynthetic Acclimation to Temperature in the Desert Shrub, Larrea divaricata: I. Carbon Dioxide Exchange Characteristics of Intact Leaves.
Larrea divaricata, a desert evergreen shrub, has a remarkable ability to adjust its photosynthetic temperature response characteristics to changing temperature conditions. In its native habitat on the floor of Death Valley, California, plants of this C(3) species when provided with adequate water are able to maintain a relatively high and constant photosynthetic activity throughout the year eve...
متن کاملHigh temperature acclimation of C4 photosynthesis is linked to changes in photosynthetic biochemistry.
With average global temperatures predicted to increase over the next century, it is important to understand the extent and mechanisms of C4 photosynthetic acclimation to modest increases in growth temperature. To this end, we compared the photosynthetic responses of two C4 grasses (Panicum coloratum and Cenchrus ciliaris) and one C4 dicot (Flaveria bidentis) to growth at moderate (25/20 degrees...
