Title	A chimeric gene (orf256) is expressed as protein only in cytoplasmic male-sterile lines of wheat
Journal	Plant Molecular Biology
Year	1994
Volume	26
Pages	535-539
Author	Song J Hedgcoth C
Abstract	Mitochondria derived from Triticum timopheevi have a chimeric gene, orf256, immediately upstream from coxI Antibodies to a peptide corresponding to a part of the encoded amino acid sequence of orf256 detect a 7 kDa protein on u-estern blots of mitochondrial proteins from cytoplasmic male-sterile (cms) wheat (T aestivum nucleus, T. timopheevi mitochondria) but not in mitochondrial proteins from T. aestivum, T. timopheevi, or cms plants restored to fertility by introduction of nuclear genes for fertility restoration. The 7 kDa protein appears to serve as a marker for cms wheat. Its occurrence as an integral protein of the inner membrane may indicate a cms effect through an influence on mitochondrial membrane function.
