Quantification of Mitochondrial DNA Copies in Central Cells of Antirrhium majus

Abstract:

The mitochondrial DNA (mtDNA) copies of Antirrhinum majus were measured by quantitative PCR method. The results showed that the mean volume of central cell of A. majus was (61570±732) μm³ with (783±25) mtDNA copies. There were similar ratio of volume to mtDNA copy between central cell and egg cell. It was presumed that the abundant mtDNA in central cell might reserve for the early development of endosperm cells.
