AB  - Taking advantage of advanced high performance liquid chromatography–electrospray tandem–mass spectrometry (HPLC–ESI–MS/MS), we screened daily changes in concentrations of endogenous phytohormones of in vitro grown potato (Solanum tuberosum L. cv. Désirée) shoot cultures and checked for possible connections between the rhythmicity of endogenous phytohormones and phototropic bending capacity of the same cultures. Studies done under diurnal 16 h light and 8 h darkness (diurnal) and continuous light (CL) conditions showed prominent daily rhythmicity of endogenous phytohormone levels in both light regimes. Phototropic bending in potato is known to be rhythmic only in the diurnal, whereas in CL conditions the bending response is present but without any daily rhythmicity. For all of the studied phytohormone groups significant differences between the diurnal and CL conditions were found. Changes in the concentration of indole auxins, indole-3-acetic acid (IAA) and its catabolite 2-oxindole-3-acetic acid (OxIAA), were the most prominent. Their levels clearly alternated with level of IAA being high in diurnal and OxIAA in CL conditions. Significant concentration changes were also observed for other phytohormones such as cytokinin ribosides, salicylic acid, abscisic acid and phaseic acid. Observed changes in daily phytohormone levels indicate strong and complex involvement of diverse phytohormone groups in realization of the phototropic bending response of potato shoots.

AB  - A number of scientific reports published to date contain data on endogenous levels of various phytohormones in potato (Solanum tuberosum L.) but a complete cytokinin profile of potato tissues, that would include data on all particular molecular forms of cytokinin, has still been missing. In this work, endogenous levels of all analytically detectable isoprenoid cytokinins, as well as the auxin indole-3-acetic acid (IAA), and abscisic acid (ABA) have been determined in shoots and roots of 30 day old in vitro grown potato (cv. Désirée). The results presented here are generally similar to other data reported for in vitro grown potato plants, whereas greenhouse-grown plants typically contain lower levels of ABA, possibly indicating that in vitro grown potato is exposed to chronic stress. Cytokinin N-glucosides, particularly N7-glucosides, are the dominant cytokinin forms in both shoots and roots of potato, whereas nucleobases, as the bioactive forms of cytokinins, comprise a low proportion of cytokinin levels in tissues of potato. Differences in phytohormone composition between shoots and roots of potato suggest specific patterns of transport and/or differences in tissue-specific metabolism of plant hormones. These results represent a contribution to understanding the hormonomics of potato, a crop species of extraordinary economic importance.
