Spatial expression pattern of MtD27 in M. truncatula roots and nodules. The MtD27 spatial expression pattern was analyzed in M. truncatula transgenic roots expressing an MtD27 promoter-reporter GUS construct. a Cross-section through a non-inoculated root. Arrowheads indicate casparian strips, which mark the endodermal cell layer. b Mock-treated control root. c Root treated with S. meliloti LCOs (10-9 M) for 3 h. d Root at four days post inoculation (dpi) with S. meliloti strain 2011. e Root at 7 dpi. f Longitudinal section through a root at 2 dpi. g Longitudinal section through a nodule primordium (7 dpi). The infection thread is indicated with an arrowhead. h Longitudinal section through an eighteen-day-old nodule. Scale bars are equal to 25 μm (a, f and g), 0.5 mm (b-e) and 50 μm (h). Sections were counterstained with Ruthenium Red
