Gene Details:

• Gene ID:
• Gene Symbol: PpCBF1
• Gene Name: C-repeat binding factor 1
• Genome:
• Species: Prunus persica

Functional Descriptions:

• The overexpression of a peach CBF (PpCBF1) gene in a transgenic line of own-rooted apple (Malus×domestica) M.26 rootstock (T166) trees was previously reported to have additional effects on the onset of dormancy and time of spring budbreak.
• No PpCBF1 transcript was detected in the phloem or cambium of RG scions grafted on T166 rootstocks indicating that no graft transmission of transgene mRNA had occurred.
• Constitutive overexpression of the PpCBF1 in apple resulted in a 4–6°C increase in freezing tolerance in both the non-acclimated and acclimated states, respectively, compared with untransformed M.26 trees.
• In contrast to own-rooted T166 trees, no impact of PpCBF1 overexpression in T166 rootstocks was observed on the onset of dormancy, budbreak or non-acclimated leaf-cold hardiness in RG/T166 trees.
• Overexpressing PpCBF1 exhibited all the characteristics observed in growth chamber studies, including enhanced cold hardiness in acclimated and non-acclimated leaves, growth inhibition, early dormancy and premature leaf senescence.
