The expression of the Agrobacterium tumefaciens emrAB operon, which encodes a membrane fusion protein and an inner membrane protein, is inducible by various flavonoids, including apigenin, genistein, luteolin, naringenin, and quercetin. Among these flavonoids, quercetin is the best inducer, followed
Tea (Camellia sinensis) is an important commercial crop, in which the high content of flavonoids provides health benefits. A flavonoid glycosyltransferase (CsUGT73A20), belonging to cluster IIIa, was isolated from tea plant. The recombinant CsUGT73A20 in Escherichia coli exhibited a broad substrate
