AFLP Analysis of Mitochondrial DNA from a Cytoplasmic Male Sterility Line and its Maintainer in Pepper （Capsicum annuum L.）

Cytoplasmic male sterility （CMS） is a maternally inherited trait characterized by the inability of a plant to produce functional pollen, which is widespread among higher plants. CMS system is a valuable tool for plant brc, ders to utilize in hybrid seed production and for molecular biologists to study the interaction between nuclear and mitochondrial genomes. Investigations into the molecular mechanism of CMS in several species have revealed that the incompatible nuclear-mitochondrial interactions leading to new chimeric mitochondrial genes such as T-urfl3 for Texas male sterility cytoplasm in maize, pcfin petunia, orf522 in sunflower, orf107 in sorghum and orf244 gene in Brassica may be responsible for CMS （Dewey et al., 1986; 1987; Young and Hanson,1987; Nivison and Hanson, 1989; Kohler et al., 1991; Moneger et al., 1994; Tang et al., 1996; Handa et al., 1995; Singh and Brown, 1991）.
