| 中文摘要: |
| 植物细胞质雄性不育是指植物的生殖器官不能产生雄配子，而雌器官发育正常， 可接受外来花粉正常结实的一种生物学现象。细胞质雄性不育是由核基因和线粒体基因互作共同起作用，影响了植物花药的绒毡层和正在进行减数分裂的细胞，从而导致植物体花粉产生败育。在生产上细胞质雄性不育对于作物杂种优势的利用、杂交种的制种都有重要意义。雄性不育现象无论是在遗传方向还是分子水平上一直以来都是科学家们研究的热点，深入研究细胞质雄性不育的机制有利于更有效地在生产上加以利用。对近年来植物细胞质雄性不育中发现的细胞质雄性不育基因的来源及分类、细胞质雄性不育与杂种优的相互关系、细胞质雄性不育的机理及目前发现的细胞质雄性不育基因进行概述，并探讨了植物细胞质雄性不育研究的发展前景。 |
| 英文摘要: |
| Plant cytoplasmic male sterility refers to a biological phenomenon in which the reproductive organs of plants cannot produce male gametes, while female organs develop normally and accept normal pollen. Cytoplasmic male sterility is a combination of nuclear gene and mitochondrial gene interaction, affecting the tapetum of plant anthers and cells undergoing meiosis, resulting in abortion of plant pollen. In the production of cytoplasmic male sterility for the utilization of crop heterosis, hybrid seed production is of great significance. Male sterility has always been a hotspot for scientists in both genetic and molecular levels. The in-depth study of cytoplasmic male sterility is beneficial for more efficient use in production. The origin and classification of cytoplasmic male sterility genes found in plant cytoplasmic male sterility in recent years, the relationship between cytoplasmic male sterility and hybrid traits, the mechanism of cytoplasmic male sterility and the current discovery of cytoplasmic male sterility genes and explored the development prospects of plant cytoplasmic male sterility research. |
