Figure 3 in Agrobacterium-mediated gene delivery and transient expression in the red macroalga Chondrus crispus

Figure 3: Histochemical staining and low-power microscopic analysis of Chondrus thallus segments for transient expression of GUS 7 days after co-cultivation. (A) Pin-pricked thalli co-cultivated without bacteria, (B) pin-pricked thalli co-cultivated with untransformed LBA4404 bacteria, (C) unwounded and untransformed thalli, (D) pin-pricked thalli co-cultivated with LBA4404/pRI 910 (no GUS gene), (E) thalli transformed with LBA4404 (pCAMBIA 1301), scale bar: 1 cm.
