Spatial expression pattern of MtCCD7 and MtCCD8 in M. truncatula nodule primordia and mature nodules. Expression patterns were analyzed in M. truncatula transgenic roots expressing promoter-reporter GUS constructs. a Longitudinal section through a root expressing the pMtCCD7::GUS construct 2 days post inoculation (dpi) with S. meliloti strain 2011. b Longitudinal section through a root expressing the pMtCCD8::GUS construct at 2 dpi. Arrowhead points at an infection thread growing inside the root hair cell. c Longitudinal section through a mature nodule expressing the pMtCCD7::GUS construct. d Longitudinal section through a mature nodule expressing the pMtCCD8::GUS construct. Scale bars are equal to 50 μm. Sections were counterstained with Ruthenium Red
