How Mitochondrial genes control CMS?


Mitochondrion is a semiautonomous organelle and power house of cell. The reported cms DNA sequences encode small transmembrane protiens that are 10-35 kda in size and cytotoxic. The specific accumulation of cytotoxic cms protiens with the tapetum frequently causes altred mitochondrial functions such as atp synthesis and chromosomal programmed cell death(pcd) in sporophytic and gametophytic cell leading to male sterility.
