Divergence time estimation of Gymnosporangium species using the rDNA dataset.
The chronogram was obtained from the molecular clock analysis using BEAST. The Ravenelia (Raveneliaceae, Pucciniales) fossil was served as a reliable calibration point to estimate the divergent time of Gymnosporangium species. Species with aecial host on Malus species were indicated in red color. The estimated divergence time of telial and aecial hosts were indicated below the geographic time scale. In addition, the potential number of telial and aecial host genera was pointed out following the name of the species based on Kern (1973) and our study.
