abstract：:The cold-sensitive mutant strain of Neurospora crassa, crib-1 (PJ30201) has a conditional defect in ribosome biosynthesis. At 10 °C this mutant underproduces the small (37S) ribosomal subunit. Experiments were done to study rRNA synthesis in crib-1 after a shift from the permissive (25 °C) to the nonpermissive tempera...
