Methylation of GCGG sites of the patatin promoter is organ-specific and inversely correlates with its activity

Abstract

327 The degree of methylation of the tuber-specific class I patatin promoter in different organs of potato plants was estimated by restriction PCR using methyl-sensitive restriction endonuclease Aci I. It was established that the degree of methylation of these sites is different in different organs: it is minimal in tubers and maximal in roots and stems. Inverse correlation between the degree of methylation of GCGG sites of the promoter and the level of its activity in plant organs was discovered. Thus, a new possibility to control the activity of this promoter by modulating its methylation appeared, which can be used in modern plant biotechnology.
