🌱Seedling emergence needs active mitochondria but that invites damage. Enter SPL2, a mitochondrial E3 ligase. It degrades outer membrane proteins to reduce ER-mitochondria tethering & mitophagy Light boosts SPL2. Mitophagy drops. Seedling pushes via soil #plantscience www.nature.com/articles/s41...

This study reveals a mechanism by which plants control mitochondrial quality during seedling emergence. The authors identify the protein SPL2, which tags damaged mitochondria for degradation, thereby ...
