Description	Oral presentation at the symposium of the Czech Plant Experimental Biology Society "11. dny fyziologie rostlin", presented by Alena Kuderova in Olomouc, Czech Republic, July, 2007. Cytokinin (CK) has been known to inhibit primary root elongation. We examined the effects of conditional CK overproduction on root architecture and lateral root primordia (LRP) development, and considered its temporal aspect during the early root development of Arabidopsis thaliana. For that purpose, we employed the pOp/LhGR system to induce ectopic IPT overexpression at designated developmental points. Our findings also suggest a negative role of CKs in the regulation of asymmetric auxin distribution during LRP development.
