Résumé

Susceptibility to chilling injury prevents the cultivation of many important crops and limits the extended storage of horticultural commodities. Although freezing tolerance is acquired through cold-induced gene expression changes mediated in part by the CBF family of transcriptional activators, whether plant chilling resistance or sensitivity involves the CBF genes is not known. The authors report in the article that an Arabidopsis thaliana mutant impaired in the cold regulated expression of CBF genes and their downstream target genes is sensitive to chilling stress.
