Heterogeneity of 5S RNA in fungal ribosomes

EU Selker, JN Stevens, and RL Metzenberg

Neurospora crassa has at least seven types of 5S RNA genes (alpha, beta, gamma, epsilon, delta, zeta, and eta) with different coding regions. A high resolution gel electrophoresis system was developed to separate minor 5S RNA's from the major 5S RNA (alpha). A study of several Neurospora crassa strains, four other species in the genus Neurospora, members of two closely related genera, and three distantly related genera demonstrated that 5S RNA heterogeneity is common among fungi. In addition, different 5S RNA's are present in Neurospora ribosomes. The finding that fungal ribosomes are structurally heterogeneous suggests that ribosomes may be functionally heterogeneous as well.
