Outline of Final Research Achievements |
For the purpose of development of production system for functional RNA from methanol using methylotrophic yeasts which have strong methanol-inducible gene expression and can grow at high cell density, we investigated formation and dynamics of RNA granules, P-bodies and stress granules (SGs), which are involved in storage and degradation of mRNA. We also analyzed intracellular dynamics of mRNAs which are highly transcribed during growth on methanol. Formation of P-bodies was observed under various stress conditions and during growth on methanol, but SGs were observed only under high-temperature condition. Furthermore, we revealed that a stress responsive regulator Hog1 is recruited to SGs under high-temperature condition.
