概要 Many plant species increase their freezing tolerance during exposure to low, non-freezing temperatures, a process termed cold acclimation. In the present study, we used a combination of immunohistochemical, chemical and spectroscopic analyses to characterize the cell walls of Arabidopsis thaliana and characterized a mutant in the XTH19 gene, encoding a xyloglucan endotransglucosylase/hydrolase (XTH). The mutant showed reduced freezing tolerance after both cold and sub-zero acclimation, compared to the Col-0 wild type, which was associated with differences in cell wall composition and structure Our data shed new light on the potential roles of cell wall remodeling for the increased freezing tolerance observed after low temperature acclimation.
