A unique two-gene gametophytic male sterility system in sorghum involving a possible role fo RNA editing in fertility restoration

Article Abstract:

Cytoplasmic male sterility (CMS) is required to produce F1 hybrid grain sorghum. The sorghum line IS1112C has a male sterility-inducing cytoplasm when introduced into nuclear background without fertility restoration genes. The formation of orf107, a chimeric open reading frame, results from an mtDNA chimeric configuration. Orf107 transcription is driven by three promoters; and fertility restoration is exacted via a unique two-gene gametophytic system, requiring the action of Rf3 and Rf4 genes. It is possible that Rf4 may confer the restitution of normal editing frequency.

Mitochondrial gene organization and expression in petunia male fertile and sterile plants

Article Abstract:

Details regarding gene structure and expression of the petunia CMS-associated fused gene (pcf) locus and its fertile homologues in Petunia, are reported. The cytoplasmic male sterility (CMS)-associated region of Petunia seem to carry novel recombinant genes, possibly created by unusual spontaneous recombination events. Restorer genes may occur due to recognition of a sequence in the DNA, RNA or protein product of a novel mitochondrial gene.
