Is there genetic variation in mycorrhization of Medicago truncatula?

ABSTRACT: Differences in the plant's response among ecotypes or accessions are often used to identify molecular markers for the respective process. In order to analyze genetic diversity of Medicago truncatula in respect to interaction with the arbuscular mycorrhizal (AM) fungus Rhizophagus irregularis, mycorrhizal colonization was evaluated in 32 lines of the nested core collection representing the genetic diversity of the SARDI collection. All studied lines and the reference line Jemalong A17 were inoculated with R. irregularis and the mycorrhization rate was determined at three time points after inoculation. There were, however, no reliable and consistent differences in mycorrhization rates among all lines. To circumvent possible overlay of potential differences by use of the
