New Beginnings: Mitochondrial Renewal by Massive Mitochondrial Fusion

Trends Plant Sci. 2017 Aug;22(8):641-643. doi: 10.1016/j.tplants.2017.06.005. Epub 2017 Jun 13.

Abstract

Massive mitochondrial fusion (MMF) in germinating arabidopsis seeds, together with earlier studies, suggests a significant role for MMF in the life cycle of flowering plants. MMF is likely to facilitate nucleoid transmission, mitochondrial DNA (mtDNA) recombination, and the homogenization of mitochondrial components, thus providing a type of quality control for mitochondrial populations in new generations.

Keywords: massive mitochondrial fusion; mitochondria; mitochondria quality control; nucleoid transmission.
