“…Analysis of the cytokinin content in these plants compared to the relative gene expression of the transgene clearly shows that overexpression of IPT or CKX has an effect on levels of the different cytokinin metabolites. This is in agreement with previous studies using P ssu-ipt or 35S:CKX1 transgenic tobacco plants (Synková et al 1999 , 2003 , 2006 ; Werner et al 2001 , 2008 ; Polanská et al 2007 ). These studies also show that an alteration of the endogenous cytokinin content has a tremendous effect on morphological level (root/shoot formation, chloroplast ultrastructure) but also functionally (effect on photosynthesis, sink-source relationship).…”

“…Our hypothesis is that cytokinins might affect the regulation of gene expression, since it was shown that cytokinins can influence chlorophyll biosynthesis (Reski 1994 ) and the electron transport chain (Synková et al . 2003 ).…”
