Time-dependent deacclimation after cold acclimation in Arabidopsis thaliana accessions
During low temperature exposure, Arabidopsis thaliana and many other plants from temperate climates increase in freezing tolerance in a process termed cold acclimation. However, the correct timing and rate of deacclimation, resulting in loss of freezing tolerance and initiation of growth is equally important for plant fitness and survival. While the molecular basis of cold acclimation has been ...
متن کاملSucrose helps regulate cold acclimation of Arabidopsis thaliana
A test was carried out to see if sucrose could regulate cold-acclimation-associated gene expression in Arabidopsis. In plants and excised leaves, sucrose caused an increase in GUS activity, as a reporter for the activity of the cold-responsive COR78 promoter. This increase was transient at 21 degrees C but lasted for at least 4 d at 4 degrees C in continuous darkness. However, at 4 degrees C wi...
متن کاملAlterations in detergent-resistant plasma membrane microdomains in Arabidopsis thaliana during cold acclimation.
Microdomains in the plasma membrane (PM) have been proposed to be involved in many important cellular events in plant cells. To understand the role of PM microdomains in plant cold acclimation, we isolated the microdomains as detergent-resistant plasma membrane fractions (DRMs) from Arabidopsis seedlings and compared lipid and protein compositions before and after cold acclimation. The DRM was ...
متن کاملFlavonoids are determinants of freezing tolerance and cold acclimation in Arabidopsis thaliana
In plants from temperate climates such as Arabidopsis thaliana low, non-freezing temperatures lead to increased freezing tolerance in a process termed cold acclimation. This process is accompanied by massive changes in gene expression and in the content of primary metabolites and lipids. In addition, most flavonols and anthocyanins accumulate upon cold exposure, along with most transcripts enco...
متن کاملA Global Survey of Gene Regulation during Cold Acclimation in Arabidopsis thaliana
Many temperate plant species such as Arabidopsis thaliana are able to increase their freezing tolerance when exposed to low, nonfreezing temperatures in a process called cold acclimation. This process is accompanied by complex changes in gene expression. Previous studies have investigated these changes but have mainly focused on individual or small groups of genes. We present a comprehensive st...
