The pBI101-CRE/LOX-RUBY system. A. Schematic of the all-in-one CRE/LOX-RUBY system to trace cell lineage in vivo. B. Schematic of plasmid vector pBI101-CRE/LOX-RUBY. C, D. Images of the pBI101-WOX11_pro-CRE/LOX-RUBY transgenic line, showing positive red betalain signal in adventitious roots developed from detached leaves. Seedlings were germinated on DEX-free ½ MS medium, grown for 12 days, and first-pair leaves were detached and cultured on B5 medium with 10 μM DEX treatment (+ DEX) for 7 days. Two independent lines were analyzed and showed the same results. Scale bars, 1 mm in (C, D)
