Outline of Final Research Achievements |
Because proliferating cells pay a high cost to the biogenesis of ribosomes, it is important to control the number of ribosomes adjusting to the environment. To understand how the number of ribosomes is adjusted to the environmental growth conditions, we measured the fraction of mRNA of the ribosome protein genes out of the total mRNA (r-fraction) by using DNA microarray in various culture conditions and mutants. As a result, the control mechanism specific for ribosomal protein genes and the global mechanism for the whole genome worked cooperatively to cause the change of the r-fraction.
