植物赤霉素矮化突变体研究进展

赤霉素(GAs)在植物种子萌发、茎的伸长和花的发育等方面起着非常重要的作用。近年来，随着研究手段和技术不断进步，对赤霉素(GA)生物合成和信号传导过程中相关基因的研究取得了惊人的进展。与GA有关的矮化突变体主要有GA缺陷型和不敏感型两类，本文对与GA生物合成和信号传导过程中有关的这两类矮突变体的研究进展进行综述。对这些这些突变体的研究促进了对赤霉素生物合成和信号传导途径的认识，同时为赤霉素更好地利用提供了科学依据。

The deveplment of dwarf mutants related gibberellin

Gibberellins(GAs) play an important role in many aspects of plant growth and development,such as seed germination,stem elongation and flower development. In recent years,with the development of research methods and technology,great progresses had been made in identifying many genes related gibberellin biosynthesis and gibberellin signal transduction pathway. There are two kinds dwarf mutants mainly related gibberellin,one is gibberellin deficient dwarf mutants,and the other is gibberellin insensitive dwarf mutants. The development of two kinds dwarf mutants involved in gibberellin biosynthesis and signal transduction pathway were summarized. The work is helpful to understand gibberellin biosynthesis and signal transduction pathway,in the same time,the development can be used as science theory for taking advantage of gibberellin in production.
