TITTLE:Regulation of mitochondrial proteostasis in plant

ABSTRACT:

Mitochondrial function is controlled by two separate genomes. This feature makes mitochondria prone to proteotoxic stress in case a stoichiometric imbalance occurs between nuclear- and mitochondrial-encoded proteins. Such a proteotoxic stress is known to induce the mitochondrial unfolded protein response (UPRmt). Our research on UPRmt not only highlight the universal nature of key features of mitonuclear stress signaling pathways, but also indicate specific effectors and transcriptional circuits that are divergent between the plant and animal kingdoms. Our studies ascertains that the network of mitochondrial protein quality control pathways is conserved in plants and that hormone signaling is an essential mediator that regulates mitochondrial proteostasis.
