Expression of a sweet cherry DREB1/CBF ortholog in Arabidopsis confers salt and freezing tolerance
Dehydration responsive element binding protein 1 (DREB1)/C-repeat binding factor (CBF) induces the expression of many stress-inducible genes in Arabidopsis. We have previously reported the identification of three DREB1/ICBF homologs from sweet cherry (Prunus avium). To identify the function of these...

| Zusammenfassung: | Dehydration responsive element binding protein 1 (DREB1)/C-repeat binding factor (CBF) induces the expression of many stress-inducible genes in Arabidopsis. We have previously reported the identification of three DREB1/ICBF homologs from sweet cherry (Prunus avium). To identify the function of these homologs, one of the genes, CIG-B, was transformed into Arabidopsis. In one of the transgenic plant lines, the DREB1/CBF target gene cor15a was induced in the absence of stress treatment. The cor15a-overexpressing transgenic plant exhibited mild growth retardation and had greater salt and freezing tolerance than did the wild-type and the transgenic lines in which cor15a was not induced. These results suggest that this sweet cherry DREB1/CBF homolog has a function similar to that of DREB1/CBF |
