¹Genomic tags were extracted from the M. grisea draft genomic sequence as described in the text.
²Significant tags are those with ≥ 2 copies per tag in RL-SAGE and ≥ 4 copies per tag in MPSS.
³Non-significant tags are those with one copy per tag in RL-SAGE and ≤ 3 copies per tag in MPSS.
⁴Significant antisense tags are those with ≥ 2 copies per tag in RL-SAGE and ≥ 4 copies per tag in MPSS matched to the annotated genes
