Potato granule-bound starch synthase promoter-controlled GUS expression: regulation of expression after transient and stable transformation

Abstract

Chimaeric genes of promoter sequences from the potato gene encoding granule-bound starch synthase (GBSS) and the β-glucuronidase (GUS) reporter gene were used to study GBSS expression and regulation. Analysis of stable transformants revealed that a GBSS promoter sequence of 0.4 kb was sufficient to result in tissue-dependent GUS expression: levels in stably… (More)
