Global gene expression analysis of pigeonpea with male sterility conditioned by A cytoplasm.

Cytoplasmic male sterility(CMS), a maternally inherited trait, provides a promising means to harness yield gains associated with hybrid vigor. In pigeonpea [Cajanus cajan (L.) Huth], nine types of sterility-inducing cytoplasm have been reported, of which A and A have been successfully deployed in hybrid breeding.
