ABSTRACT
We have cloned and sequenced the two intervening transcribed spacers in the rDNA repeat unit of three Aspergillus species--A. nidulans, A. awamori and A. wentii. The A. wentii and A. awamori spacers are almost identical and share a high degree of homology with the A. nidulans spacers. All spacers have a high G-C content (66%-76%) and the potential of forming complex secondary structures, which may indicate that they play a role in the maturation of pre-rRNA molecules.
