Proportional growth of <i>Pythium</i> species on a minimal medium (MM) containing various carbon sources to its growth on V8 juice agar.

*Clades denominations are based on Lévesque & de Cock [1414]. Species: Pyap = Pythium aphanidermatum, Pyar = Py. arrhenomanes, Pyir = Py. irregulare, Pyiw = Py. iwayamai, Pyuu = Py. ultimum var. ultimum, Pyus = Py. ultimum var. sporangiiferum, and Pyve = Py. vexans. **Values represent proportional diameter growth means of each isolate on carbon sources relative to its growth on V8 juice agar (± standard error).
