茉莉生殖发育与分子生物学特性研究分析

Study on Reproductive Development and MolecularBiological Characteristics of Jasminum sambac (L.) Aiton

茉莉花的观赏、茶用和药用价值均较高,是重要的花茶和香精原料,目前生产上使用的主要为双瓣茉莉,但双瓣茉莉经过多年的无性繁殖和长期使用会出现品种性退化,导致其抗性和产花量均降低。为全面了解茉莉生殖发育特性和分子生物学特性研究现状,本文综述了国内外关于茉莉雌、雄性生殖器官的发育,分子标记开发,遗传多样性分析及功能基因克隆等基础研究方面的进展,并对今后茉莉生殖发育和分子生物学特性方面的主要研究方向和研究重点进行了展望,以期为克服茉莉结实障碍,实现品种改良、种质创新和重要性状的分子解析及分子设计育种等提供一定的理论依据。

Jasmine [Jasminum sambac(L.) Aiton] has high values in ornament, tea and Chinese traditional medicine, and its flower is an important raw material for scenting jasmine tea and processing flavor. At present, the popularly planted cultivar is a type of double-petal jasmine. However, the cultivar will degenerate severely for a long-term of cultivation, leading to the decreases of flower yield and plant resistance. For full understanding the research status of jasmine reproductive developmental and molecular characteristics, this paper reviewed the fundamental research advances, including the development of male and female reproductive organs, molecular markers development, genetic diversity analysis, and functional gene clone. At the same time, the authors prospected the main research directions and key points underlying the characteristics of reproductive development and molecular biology, for the aim of providing theoretical reference to conquer the reproductive barriers and realize the goals of cultivar improvement, germplasm innovation, molecular analysis on some important traits and molecular design breeding of jasmine.
