A family of optional group-I introns was found near the 3′ end of the nuclear small subunit rRNA genes in 61 out of 70 isolates of the deuteromycete mycorrhizal fungusCenococcum geophilum. DNA sequence polymorphisms among the introns (termedCgSSU introns) from ten of the isolates were studied. The sequences, ranging in size from 488 to 514 nucleotides, were from 93.2% to 99.6% similar to each other. Mutations were less common in predicted base-paired regions (33% of all mutations) than in free… CONTINUE READING
