Abstract
We are seeking to improve our understanding of the role of the nucleus in controlling mitochondrial genome expression in higher plants. We will investigate the molecular mechanism(s) by which nuclear restorer of fertility genes (Rf1 and Rf2) regulate the expression of the novel ORF522 gene which appears to be causally related to the male sterile phenotype in sunflower. Transcription, processing and translation of the ORF522 transcript will be investigated in two series of fertile, sterile and restored hybrid lines of sunflower. The molecular function of the Rf1 and Rf2 gene products will be defined and if time allows preliminary attempts will be made to isolate corresponding cDNA clones.
