  • a Calculations are essentially the same as described for Table 2. The P. chrysosporium homolog with the highest alignment score was reported for each P. placenta gene. Scores, percent identity, and related alignment parameters for all genes are listed in Table S1 of the supplemental material. With one exception (galacturonic acid reductase), transcripts of the corresponding P. chrysosporium gene exhibited relatively lower accumulation ratios and a concomitantly higher false discovery rate (4) probability (far right column). Underlined P. chrysosporium models correspond to genes with >50 cDNA tags in medium containing powdered oak (43). Data are ranked according to the P. placenta ratio, from highest to lowest. *, detection of corresponding peptides by MS/MS in BMA medium filtrate.
