FIG 3.

Volatiles detected in at least two-thirds of all Coccidioides strains in spherule (A) or mycelial (B) cultures, with VOCs in boldface type detected in both life cycles and those in italic type detected in statistically significantly different abundances between life cycles (P < 0.05). Open shapes indicate VOCs with at least a 2-fold-higher relative abundance than in medium blanks, and solid shapes indicate VOCs with at least a 10-fold-higher relative abundance. Strains are color-coded as blue for C. immitis and red for C. posadasii. The percentages of listed VOCs detected in each strain and the percentages of strains producing each VOC are noted at the bottom and right sides of each chart, respectively. Compound identifications: 97, acetic acid; 239, 1-hexanol; 255, 2-hexen-1-ol; 383, limonene; 428, 2,4,6,-trimethylpyridine; 820, 2-butyl-1-octanol.
