Figure 4.

Phylogenetic analysis of 27 sequence types (ST) and the summary of source and count of isolates. Light wheat panel shows phylogenetic tree based on the concatenated sequences of the 7 housekeeping genes, the scale bar refers to a phylogenetic distance of 0.002; light yellow panel shows the sequence alignment of the 7 housekeeping genes, highlighting bases that are not the most common base in that position with red dots representing adenine (A), blue dots representing cytosine (C), green dots representing guanine (G), and purple dots representing thymine (T); and the light gray panel shows the sample source and isolate counts for each ST, with red squares indicating disease-related isolates and green squares indicating asymptomatic (ASX) isolates. The numbers in each square represent the isolate count for the corresponding category. The shade of each square represents the proportion (or frequency) of the total isolate count (isolate count/total isolates) for each sequence type (ST).
