Cytological characterization of a thermo-sensitive cytoplasmic male-sterile wheat line having K-type cytoplasm of Aegilops kotschyi
Male sterility is an important tool for obtaining crop heterosis. A thermo-sensitive cytoplasmic male-sterile (TCMS) line was developed recently using a new method based on tiller regeneration. In the present study, we explored the critical growth stages required to maintain thermo-sensitive male sterility in TCMS lines and found that fertility is associated with abnormal tapetal and microspore...

متن کاملGenetic Mapping of an Aegilops tauschii–derived Hessian Fly Resistance Gene in Common Wheat
Hessian fl y [Mayetiola destructor (Say)] is a major threat to wheat (Triticum aestivum L.) production in the eastern United States. Cultivar releases containing major Hessian fl y resistance genes have proven effective in minimizing losses caused by this pest. Nevertheless, the ephemeral nature of major gene resistance necessitates the identifi cation of novel sources of resistance. Hessian fl...
متن کاملMitochondrial DNA heteroplasmy in wheat, Aegilops and their nucleus-cytoplasm hybrids.
A mitochondrial (mt) transcriptional unit, nad3-orf156, was studied in the nucleus-cytoplasm hybrids of wheat with D/D2 plasmons from Aegilops species and their parental lines. A comparative RFLP analysis and sequencing of the random PCR clones revealed the presence of seven sequence types and their polymorphic sites were mapped. All the hybrids possessed the paternal copies besides the materna...
متن کاملRadiation hybrid mapping of the species cytoplasm-specific (scsae) gene in wheat.
Radiation hybrid (RH) mapping is based on radiation-induced chromosome breakage and analysis of chromosome segment retention or loss using molecular markers. In durum wheat (Triticum turgidum L., AABB), an alloplasmic durum line [(lo) durum] has been identified with chromosome 1D of T. aestivum L. (AABBDD) carrying the species cytoplasm-specific (scsae) gene. The chromosome 1D of this line segr...
