植物温敏雄性不育分子机理研究进展(英文)

Research Advances in Molecular Mechanism of Thermo-sensitive Genic Male Sterility in Plants

温敏雄性不育在作物杂种优势利用上特别具有优越性。迄今,已在许多植物中发现温敏雄性不育系,并广泛用于两系法杂交育种。随着分子生物学的飞速发展,目前已从分子水平揭示温敏雄性不育的本质,为其进一步开发与利用奠定了基础。该研究从基因分子定位、基因差异表达等方面综述了植物温敏雄性不育的育性转换分子机理,并深入探讨了导致温敏雄性不育的基因差异表达的机制。

Thermo-sensitive genic male sterile （TGMS） lines have specific superiority in heterosis utilization of crops. So far, thermo-sensitive genic male sterile lines have been found in many plants and are widely used in two-line hybrid breeding. With the rapid development of molecular biology, the molecular nature of thermo-sensitive genic male sterility has been revealed, which lays the foundation for further devel- opment and utilization of thermo-sensitive genic male sterile lines. In this study, the molecular mechanisms of fertility conversion of plant thermo-sensitive genic male sterile lines were reviewed from gene molecular mapping and gene differential ex- pression, and the mechanisms of gene differential expression in thermo-sensitive genic male sterile lines were further discussed.
