however, few instances of these proteins have been described in plants. Arabidopsis
(Arabidopsis thaliana) PROHIBITIN 3 (PHB3) is involved in stress responses and
developmental processes, but it is unknown how these roles are achieved at the molecular
level in the nucleus. In this study, we show that nucleo-mitochondrial PHB3 plays an
essential role in regulating genome stability and cell proliferation. PHB3 is up-regulated by …
