Abstract

The expression of a mitochondrially encoded novel open reading frame appears to be causally related to the cytoplasmic male sterile (CMS) phenotype in most plants systems. However, how these novel protein(s) cause disruption of pollen development is unknown. Based on our preliminary data, we have proposed a hypothesis which suggests that, in sunflower, mitochondrial dysfunction is caused by the novel CMS specific ORF522 protein which is associated with the F1-F0-ATPase complex. We propose to investigate mitochondrial function in fertile, sterile and restored hybrid sunflowers, focussing on the assembly and function of the F1-F0-ATPase complex and the possible role of mitochondria in programmed cell death during male flower development.
