FIG. 3.

Maximum likelihood mapping analysis with concatenated sequence and single-locus data by grouping of X. fastidiosa by subspecies: X. fastidiosa subsp. pauca (citrus and coffee), X. fastidiosa subsp. piercei (grape), X. fastidiosa subsp. sandyi (oleander), and X. fastidiosa subsp. multiplex (oak, peach, and almond). Values in the different regions of the equilateral triangle indicate support for possible tree topologies. Strong support for specific topologies is indicated by high values at single vertices of the triangle.
