• In addition, ProACT:CRL5/WT showed a cytokinin-resistant phenotype for crown root initiation, and also up-regulated the expression of two negative regulators of cytokinin signaling, OsRR1 and OsRR2, which were downregulated in crl5
• Furthermore, ERF3-regulated RR2 expression was involved in crown root initiation, while the ERF3/WOX11 interaction likely repressed RR2 during crown root elongation.
• The expression of ERF3 and WOX11 only partially overlapped, underlining a spatio-temporal control of RR2 expression and crown root development.
