[Mechanism of action of the plant hormone jasmonate. 1. Jasomonate-interacting proteins that regulate transcription of the p. pinII potato gene].
A fragment containing the regulatory region of the p. pinII gene was isolated from potato DNA by polymerase chain reaction. Interactions of this DNA region with jasmonate determines the transcriptional activation. The isolated DNA fragment was cloned into the pTE2pb plasmid, which was used for preparing an affinity sorbent. Using this sorbent, four proteins were isolated from the total protein capable of desorption at physiological concentration of jasmonate. These proteins are likely to be subunits of two transcription repressors, whereas jasmonate serves as an inducer. Three sequences of the regulatory regions (boxes G, I, and III) are binding sites for repressors; similar sequences were found in various plant genes activated by jasmonate.
