Niche differentiation and evolution of the wood decay machinery in the invasive fungus Serpula lacrymans

摘要

A Weight loss of target strains on different wood types. Percent weight loss indicates the dry weight lost after 60 days of inoculation. Significant differences are indicated according to Kruskal–Wallis rank sum test (P < 0.05). B Experimental set up of the competition experiment. C Proportions of competitors recovered from substrate in a pairwise competition setup containing equal amounts of wood blocks inoculated with strain pairs. A proportion of 0.5 indicates no gain or loss of substrate, while proportions > 0.5 indicate substrate gain by competitor B and proportions < 0.5 indicate substrate gain by competitor A. Significant deviation from equal outcome (0.5) was tested using a χ2 goodness of fit test (df = 1). Bold: P ≤ 0.05; Bold*P < = 0.01. A.x. Antrodia xantha, F. p. Fomitopsis pinicola, C.p. Coniophora puteana. Sample sizes for each pair ranged from 19 to 48 observations (Supplementary Table S1).
