  1. (a) Approximate position indicated in kb; (b) also contains atypical 18s and 28s; (c) 18s and 5.8s are of S-type and 28s is divergent (65% A-type and 75% S-type); (d) 18s is missing from these units; (e) 3 tandem repeats of 5s. Data compiled from [5] and PlasmoDB. (f) Most of these ESTs clustered with homologous loci of both chromosomes 5 and 7.
