Purification of Mitochondria from Arabidopsis

Plant cells contam different subcellular compartments, which serve distinct phystologrcal functions. One of these organelles, the mitochondrion, provides most of the nonphotosynthetrc energy required m the cell. Mitochondria contain their own genome(s), but encode only a small number of vita1 gene products. Simrlar plastids, the majority of the organellar proteins are nuclear encoded, and imported into these organelles.
