Ethylene and cold participate in the regulation of LeCBF1 gene expression in postharvest tomato fruits
Copyright policy )Ethylene and cold participate in the regulation of LeCBF1 gene expression in postharvest tomato fruits
C‐Repeat/dehydration‐responsive element binding factor (CBF) is a transcription factor regulating cold response in plants, of which little is known in fruits. We showed a double‐peak expression pattern of Lycopersicon esculentum putative transcriptional activator CBF1 (LeCBF1) in mature green fruit. The peaks appeared at 2 and 16 h after subjection to cold storage (2 °C). The second peak was coincident with, and thus caused by a peak in endogenous ethylene production. We showed that LeCBF1 expression was regulated by exogenous ethylene and 1‐methylcyclopropene, and was not expressed without cold induction. LeCBF1 expression was different in the five maturation stages of fruits, but expression peaked at 2 h at all stages.
