Cold acclimation (CA) is a process whereby plants in response to low but non-freezing temperatures undergo a range of biological changes in order to increase their frost tolerance (FT) and prepare for the winter season [1]. From:Plant Science,2011 ...
Here, changes in vascular bundle (VB) structure at the leaf petiole were analysed together with sucrose exudation rates before and after cold acclimation. Six natural accessions originating from southern and northern Europe were compared. Photosynthetic efficiency, that is, maximum and effective quantum...
Understanding how plants acquire cold acclimation is valuable for the improvement of the freezing tolerance in plants and for predicting the effects of climate change on plant distribution and agricultural yield. 展开 关键词: CBFs, CAMTAs, Protein kinase, Cold-responsive gene, ...
Cold acclimation and development of freezing and drought tolerance in plants Plant growth, productivity and distribution are severely limited by environmental stresses including drought, salinity and freezing, all of which disturb the water balance of the cell. Plants have evolved different adaptive strate...
Cold acclimation did not occur when temperatures were low if light intensity was low, even in winter peas. In contrast, with regular light intensity, the winter peas acquired more freezing tolerance than spring peas and a close relationship was found between the soluble sugar concentration of ...
the activity of RNase in leaves and branches of Populus tomentosa cuttings at various periods (viz: cold acclimation, deacclimation, chilling stress and the recovery after chilling stress), and the survival rate and the freezing resistance of cuttings during cold acclimation at -3℃ were investigate...
The fundamental question in cold acclimation is how do plants perceive the low but nonfreezing temperatures that activate cold acclimation responses. New findings in the past year suggest that changes in membrane fluidity, cytoskeleton rearrangement, and calcium influxes are among the earliest events ta...
Cold-acclimation-induced changes in freezing tolerance and translatable RNA content were compared in seedlings of a relatively cold sensitive citrus species, Citrus grandis L. Osb. cv. Thong Dee (pummelo), and the cold-hardy citrus relative, Poncirus trifoliata L. Raf. cv. Pomeroy (trifoliate or...
Transcriptome analysis of cold acclimation in barley albina and xantha mutants. We found that the lack of cold regulation in the mutants is due to the presence of signaling pathway(s) normally cold activated in wild type but ... JT Svensson,C Crosatti,C Campoli,... - 《Plant Physiology》...
The effects of short-term cold stress and long-term cold acclimation on the light reactions of photosynthesis were examined in vivo to assess their contributions to photosynthetic acclimation to low temperature in Arabidopsis thaliana (L.) Heynh.. All photosynthetic measurements were made at the tempe...
