PAL inhibitor evokes different responses in two Hypericum species.

Original language description

Accumulation of secondary metabolites (general phenols, naphthodianthrones and phloroglucinol hyperforin) in Hypericum perforatum and Hypericum canariense after application of the inhibitor (2-aminoindane-2-phosphonic acid, AIP) of the pivotal enzyme ofgeneral phenylpropanoid pathway (phenylalanine ammonia-lyase, PAL) was studied. Shoots of H. perforatum revealed more expressive growth depression, concomitantly with the inhibition of PAL activity (-60%) and decrease in soluble phenols and individual phenolic acids in response to AIP. Hypericins (hypericin, pseudohypericin and protohypericin) decreased while hyperforin increased in AIP-cultured H. perforatum. On the contrary, growth changes, decreases in soluble phenols and individual phenolic acids were less-visible in H. canariense. This was also reflected in restoration of PAL activity (+330%) and selected flavonoids even increased. Hypericins and hyperforin were present in several orders of magnitude lower amounts in comparison wit
