An ethylene-responsive transcription co-activator (MBF) acts on
ethylene-responsive transcription factors (ERFs), which positively
controls the expression of ethylene-responsive plant genes. A plant is
transformed by the gene of the co-activator, and a promoter that may
increase or decrease responsiveness to ethylene depending on its
alignment. A method for controlling the responsiveness of plants to
ethylene transforms a plant comprising an ERF-dependent gene, which
positively control the expression of ethylene responsive genes of plants.
This transcription co-activator gene is applied to control ethylene
response of plants.
