In Planta Recapitulation of Isoprene Synthase Evolution from Ocimene Synthases.

abstract：:Most mitochondrial proteins are synthesized in the cytosol of eukaryotic cells as precursor proteins carrying N-terminal extensions called transit peptides or presequences, which mediate their specific transport into mitochondria. However, plant cells possess a second potential target organelle for such transit peptid...
