Effects of conditional IPT-dependent cytokinin overproduction on root architecture of Arabidopsis seedlings

Cytokinin (CK) has been known to inhibit primary root elongation and suggested to act as an auxin antagonist in the regulation of lateral root (LR) formation. While the role of auxin in root development has been thoroughly studied, the detailed and overall description of CK effects on root system mo...
