赤霉菌分子生物学研究进展

Recent Advances in The Molecular Biology of Gibberella fujikuroi

过去 1 0年中 ,由于基因克隆、遗传转化等分子生物学方法与技术的应用 ,对赤霉菌中赤霉素生物合成基因的克隆、鉴定、异源表达及其表达调控等分子生物学研究取得了很大进展。现从赤霉菌的转化系统、赤霉素生物合成基因克隆。

The ascomycetous filamentous fungus Gibberella fujikuroi , a pathogenic to plant, is important in commercial production and academy research of gibberellins which were identified as natural plant hormone controlling the plant development such as stem elongation and seed germination. However, the molecular biology of this fungus has been underdeveloped. Based on the transformation system, genes cloning, molecular biosynthetic pathway of gibberellins and the regulation of the corresponding genes, some biomolecular aspects about Gibberella fujikuroi were summarized in this paper.
