Summary
Mitochondrial DNA ofSpirodela oligorhiza (duck weed) was analyzed with restriction enzymes. The genome size appears to be at least 250 kbp. Four different PstI fragments were cloned. These four clones contain a sequence which is reiterated about 100-fold on theSpirodela mitochondrial DNA. Hybridization analysis showed that a similar sequence is present onZea mays mitochondrial DNA, although much less reiterated here. The presence of these reiterated sequences might contribute to the physical heterogeneity of plant mitochondrial DNA.
