Table 1. Frequency and diversity of 5S rRNA gene copies in the complete filamentous fungal genomes studied here.
| Genome size, Mb | Total number of gene copies | Number of intact gene copies* | Number of distinct intact copy types* | Number of pseudogene copies | Proportion of intact copies/Mb | Proportion of pseudogene copies/Mb† | |
|---|---|---|---|---|---|---|---|
| A. nidulans | 31 | 52 | 36 (0.03) | 16 (0.03) | 16 | 1.16 | 0.52 |
| M. grisea | 40 | 71 | 38 (0.01) | 17 (0.02) | 33 | 0.95 | 0.83 |
| F. graminearum | 40 | 66 | 59 (0.09) | 24 (0.12) | 7 | 1.48 | 0.18 |
| N. crassa | 43 | 92 | 78 (0.07) | 29 (0.11) | 14 | 1.81 | 0.33 |

Results for comparisons of pseudogene frequency by using a two-tailed G test were significant for A. nidulans vs. F. graminearum (P = 0.05), M. grisea vs. F. graminearum (P = 0.007), and M. grisea vs. N. crassa (P = 0.02).
