Enhanced rooting (in PGR-free and auxin-treated plants) led to elevation of the monoterpenoid/sesquiterpenoid ratio in the essential oils of aerials. On the contrary, root inhibition and intensive callusogenesis [combined cytokinin (CK) and auxin treatments] reduced this ratio more than twice, significantly enhancing sesquiterpenoid production. Both morphogenic types displayed sesquiterpenoid domination in the underground tissues, which however differed qualitatively from the sesquiterpenoids of the aerials, excluding the hypothesis of their shoot-to-root translocation and implying the possible role of another signaling factor, affecting terpenoid biosynthesis . Inhibited rooting also resulted in a significant drop of endogenous isoprenoid CK bioactive-free bases and ribosides as well as CK N-glycoconjugates and in decreased trans-zeatin (transZ):cis-zeatin (cisZ) ratio in the aerials. Marked impairment of the structural organization of the photosynthetic apparatus and chloroplast architecture were also observed in samples with suppressed rooting. It is well known that in the plant cell monoterpenoid and transZ-type CKs biogenesis are spatially bound to plastids, while sesquiterpenoid and cisZ production are compartmented in the cytosol. In the present work, interplay between the biosynthesis of terpenoids and CK bioactive free bases and ribosides in A. alba in vitro via possible moderation of chloroplast structure has been hypothesized.
