Peanut AhmTERF1 Regulates Root Growth by Modulating Mitochondrial Abundance.

ABSTRACT: Mitochondria are responsible for energy generation, as well as key metabolic and signaling pathways, and thus affect the entire developmental process of plants as well as their responses to stress. In metazoans, mitochondrial transcription termination factors (mTERFs) are known to regulate mitochondrial transcription. mTERFs have also been discovered in plants, but only a few of these proteins have been explored for their biological functions. Here, we report a role in root growth for mitochondria-associated protein AhmTERF1 in peanut (Arachis hypogaea L.). Overexpressing AhmTERF1 significantly stimulated the growth of peanut hairy roots and transgenic Arabidopsis. Surprisingly, AhmTERF1 is predominantly expressed in the root meristem where it increases m
