To put the information content in perspective, we also did simulations in which 43 random sequence data sets of length 100 nt (for flanking exons) and 109 (total number of introns analyzed) random data sets of length 29 nt (for conserved intron regions) were generated at the nucleotide frequencies of Euascomycetes rRNA and the information content of these was calculated.
The present data for the 300 - 337 spliceosomal introns, for example, when mapped on the Euascomycetes tree published in Bhattacharya et al.
The expected nucleotide probabilities were estimated from the observed nucleotide frequencies over all sites for 80 Euascomycetes rRNA sequences (A = 26%, C = 22%, G = 27%, T = 25% [ 12 ] ). The nucleotides were turned upside-down when the observed frequency was less than expected [ 45 ] . A total of 43 spliceosomal intron sites, for which 50 nt of both upstream and downstream exon sequence are available, were included in this analysis.
With our data set of 49 (two diatom-specific introns were excluded from this analysis) different spliceosomal intron sites in the SSU and LSU rRNAs of Euascomycetes (alignment available at http://www.rna.icmb.utexas.edu/ANALYSIS/FUNGINT/(for registration details please see http://www.rnq.icmb.utexas.edu/cgi-access/access/locked.cgi), we first tested for the presence of a proto-splice site flanking the introns [ 12 ] . In this chi-square analysis, the null hypothesis specified that nucleotide usage in 50 nt of exon sequence upstream and downstream of the different intron insertion sites was random and dependent on the nucleotide composition of Euascomycetes SSU and LSU rRNA sequences in general.
The large population sizes of unicellular eukaryotes may prevent widespread intron spread due to secondary mutations that lead to their loss from populations [ 42 ] . Interestingly, the lichenized Euascomycetes, which are particularly rich in both spliceosomal and group I introns in their nuclear rRNA, are typically extremely slow-growing taxa many of which have small population sizes [e.g.
