Figure 5. The CsDFR and CsANR overexpressing transgenic lines show higher contents of total flavonoids and increased flavan-3-ols content in transgenic tobacco compared to control tobaccos.

Figure 5

Three flavan-3-ols namely catechin, epicatechin and epigallocatechin were measured in CsDFR and CsANR transgenic lines vis-à-vis control tobacco. Total flavonoids in CsDFR and CsANR overexpressing transgenic tobaccos (A). The catechin (B), epicatechin (C) and epigallocatechin (D) contents in CsDFR and CsANR transgenic lines as well as control tobacco plants. Data is the mean of three replications with error bars indicating ± SD. Statistical significance is indicated as (*) for P<0.05.
