Figure 3

Histochemical localization of MtGA2ox10 promoter activity in M. truncatula roots and nodules. (A–J) M. truncatula roots transformed using the MtGA2ox10pro::GUS construct and stained using X-Gluc as a substrate. (A) Uninoculated roots expressing red fluorescent protein (RFP) at 0 hpi. (B,C) Roots at 12 hpi. (D) Deformed root hairs at 12 hpi. Arrow denotes infection thread. (E) Roots at 24 hpi. (F–J) Nodules at different stages of development (5 dpi to 6 wpi). (G–J) S. medicae expressing a LacZ construct stained using Magenta-Gal as a substrate. Scale bars are 1 mm (A,B,H–J) or 200 µm (D–G).
