Changes in cytokinin content and altered cytokinin homeostasis in AtCKX1 and AtCKX2-overexpressing centaury (Centaurium erythraea Rafn.) plants grown in vitro
Original language description
The plant hormones cytokinins (CKs) regulate a number of physiological processes. Their homeostasis is controlled by the rate of de novo synthesis and the rate of catabolism. The aim of this work was to analyze the content of total as well as individualgroups of endogenous CKs in AtCKX1 and AtCKX2-overexpressing centaury (Centaurium erythraea Rafn.) plants grown in vitro. Transgenic CKX plants represent a suitable model system for studying physiological and morphological processes controlled by CKs. Inthis work we clearly demonstrate a significant effect of AtCKX transgenes on CK metabolism in transgenic centaury plants. However, shoots and roots of only one AtCKX1 line and three AtCKX2 lines with a significant reduction of bioactive CKs were obtained. We also show that changes in the CKs metabolism considerably affected endogenous indole-3-acetic acid (IAA) levels in plant tissues. All analyzed transgenic AtCKX centaury lines exhibited decreased amount of endogenous IAA in shoots as
