^aMaize-wheat divergence time range of 50 to 80 Mya, with 60 Mya the most likely was from Wolfe et al. [34].
^bDivergence of Aveneae from Triticeae assumed to occur close to the time of divergence of Poeae from Triticeae which was estimated at 25 Mya by Gaut [37].
^cTriticum-Hordeum divergence estimated at 11.4 +/- 0.6 Mya by Huang et al. [36].
^dValue from linear regression of MEGA calculated viral divergence times with host plant divergence times assuming origin at zero.
^eValues shown are calculated from linear regression correlation and MEGA values.
