Résumé

cytokinin receptors

histidine kinase

Key words: Catharanthus roseus

A full length cDNA (CrCKR1) encoding a hybrid histidine kinase was isolated from a Catharanthus roseus cDNA library. The kinase belongs to the subfamily of cytokinin receptors represented by CRE1/AHK4/WOL in Arabidopsis thaliana. In cell suspensions, the expression of CrCKR1 is not affected by various stress and hormonal treatments but is stimulated in cells continuously exposed to cytokinin. In plants, CrCKR1 is strongly expressed only in the petals of mature flowers. These data suggest that CrCKR1 could take part in the mechanisms leading to the production of secondary metabolites in C. roseus.
