Cytokinins in shoot apices of Brassica napus plants during vernalization

Popis výsledku v původním jazyce

The putative role of cytokinins in processes leading to reproductive development of plants was investigated by analysing the shoot apical parts of a winter cultivar of oilseed rape (Brassica napus L. var. oleifera, cv. Górczański). The endogenous cytokinin levels were measured by liquid chromatography?tandem mass spectrometry (LC?MS) in the shoot apices of vegetative plants (grown at 20/17 °C with a 16/8 h day/night regime) and vernalized plants (56 days at 5/2 °C with a 16/8 h photoperiod) at differenttimes during floral transition. During vernalization, the content of all isoprenoid cytokinins increased significantly, coinciding well with the onset of the early stages of reproductive development. Cytokinin levels reached their maxima when most of the plants became irreversibly reproductive (after 42 days of cold treatment). cis-Zeatin riboside (unequivocally identified by quadrupole-time-of-flight MS) accounted for ca. 87?89% of the total isoprenoid cytokinin content in control and
