RT-PCR analysis to detect transcripts of MtPT4 , MtBCP1 and MtSCP1 in colonized cortical cells. RNA from cortical cells from two independent mock-inoculated M. truncatula root systems (LM-M1 and LM-M2) and cortical cells containing arbuscules from M. truncatula/G. versiforme mycorrhizal root systems (LM-Gv1 and LM-Gv2) was used. Cortical cells were obtained by laser microdissection (LM). *Two rounds of PCR were carried out for TC106954. A M. truncatula elongation factor 1α (TC106485) was included as endogenous control.
