Fig. 4. Phylogram illustrating relationships among sequences of X. fastidiosa amplified from symptomatic grape samples in southern New Mexico (B, C, H, I, and L) versus other reported X. fastidiosa isolates. Sequences from New Mexico grape samples are most closely related to New Mexico 1 isolate from chitalpa.
