additional information |
hairy root lines of Coleus blumei carrying HPPR or rosmarinic acid synthase (RAS) RNAi suppression and overexpression constructs are established using Agrobacterium rhizogenes-mediated transformation. Hairy root lines showing undetectable HPPR or RAS mRNA levels displayed strongly reduced rosmarinic acid contents with reduction of up to 92% compared to control hairy root lines. An increase of rosmarinic acid levels up to 176% occurs in overexpression hairy root lines with equally increased HPPR transcript levels while RAS overexpression results in co-suppression effects with reduced rosmarinic acid levels |
