The white dead nettle (Lamium album L.) is a herb that was successfully subjected to in vitro micropropagation followed by ex vitro adaptation back to the natural habitat. The L. album micropropagation system offers a combination of factors (light intensity, temperature, carbon dioxide level, humidity) that are limiting for plant growth and bioactive capacity. Here, we performed comparative investigation on the primary and secondary metabolism in fully expanded L. album leaves during the consecutive growth in in vivo, in vitro, and ex vitro conditions. The micropropagation did not affect the...
