英文摘要	Genetic modification of secondary metabolic pathways to produce desirable natural products is an attractive approach in plant biotechnology. In our study, we attempted to produce a typical soybean isoflavone genistein, a well-known health-promoting metabolite, in non-legume plants via genetic engineering. Both overexpression and antisense suppression strategies were used to manipulate the expression of several genes encoding key enzymes in the flavonoids/isoflavonoids pathway in transgenic tobacco, lettuce, and petunia. Introducing soybean isoflavone synthase (IFS) into these plants, which naturally do not produce isoflavonoids due to a lack of this leguminous enzyme.. resulted in genistein biosynthesis in tobacco petals, petunia leaves and petals, and lettuce leaves. In tobacco, when flavanone 3-hydroxylase (F3H) expression was suppressed by its antisense gene while soybean IFS was overexpressed at the same time, genistein yield increased prominently. In addition, overexpression of phenylalanine ammonia-lyase (PAL) also led to an enhanced genistein production in tobacco petals and lettuce leaves in the presence of IFS than in the plants that overexpressed only IFS.
