Characterization of new maize genes putatively involved in CK metabolism and their expression during osmotic stress in relation with cytokinin levels

Original language description

In this study, we for the first time described expression profiles of the entire gene families of CK biosynthetic and degradation genes in maize during development and stress responses. Transcript abundance of particular genes is discussed in relation tothe levels of different CK metabolites. cis-Zeatin and its derivatives were found to be the most abundant CKs in young maize seedlings. We hypothesize that this zeatin isomer could play a crucial role in the abiotic stress response and that it originated independently to de novo biosynthesis in stressed tissues most probably by elevated specific RNA degradation. By enhancing their CK levels plants could perhaps settle to a reduction of growth rates maintained by abscisic acid accumulation in stressed tissues. A second role for cytokinin receptors in sensing turgor response is hypothesized besides their documented function in CK signaling.
