Fig. 1From: A rare non-canonical splice site in Trema orientalis SYMRK does not affect its dual symbiotic functioning in endomycorrhiza and rhizobium nodulationTrema orientalis accession RG33 and Parasponia andersonii accession WU1 differ in mycorrhizal colonisation. A Comparison of mycorrhization efficiency in the root system of P. andersonii WU1 (blue) and T. orientalis RG33 (red) at 2, 4 and 6 weeks post-inoculation with Rhizophagus irregularis DOAM197198. F%: The frequency of mycorrhiza in the root system. M%: the intensity of mycorrhizal colonisation in the root system. A%: Arbuscule abundance in the root system. B a%: Averaged arbuscule abundance detected in 50 randomly selected 1 cm infected segments of a root system. Error bars represent the SE of 10 biological replicates for each 50 × 1 cm root segment that has been analysed. Analysis was done according to Trouvelot et al. (1986) [26]. C Toluidine blue-stained P. andersonii and D T. orientalis root segment visualising R. irregulates arbuscules 6 weeks post-inoculation. Size bar = 10 μmBack to article page
