Abstract

Gibberellins are produced by all vascular plants and several fungal and bacterial species that associate with plants as pathogens or symbionts. In the 60 years since the first experiments on the biosynthesis of gibberellic acid in the fungus Fusarium fujikuroi, research on gibberellin biosynthesis has advanced to provide detailed information on the pathways, biosynthetic enzymes and their genes in all three kingdoms, in which the production of the hormones evolved independently. Gibberellins function as hormones in plants, affecting growth and differentiation in organs in which their concentration is very tightly regulated. Current research in plants is focused particularly on the regulation of gibberellin biosynthesis and inactivation by developmental and environmental cues, and there is now considerable information on the molecular mechanisms involved in these processes. There have also been recent advances in understanding gibberellin transport and distribution and their relevance to plant development. This review describes our current understanding of gibberellin metabolism and its regulation, highlighting the more recent advances in this field.

赤霉素生物合成的研究现状。

摘要

赤霉素是由所有维管束植物以及与植物相关的病原体或共生体的几种真菌和细菌产生的。自首次在真菌Fusarium fujikuroi中合成赤霉素的实验以来的60年中，有关赤霉素生物合成的研究已取得进展，可提供有关这三个王国中激素产生独立发生的途径，生物合成酶及其基因的详细信息。赤霉素在植物中起激素的作用，影响其浓度受到严格调节的器官的生长和分化。当前在植物中的研究特别集中在通过发育和环境线索来调控赤霉素的生物合成和失活的调控上，并且现在关于这些过程中涉及的分子机制的信息很多。在了解赤霉素的运输和分布及其与植物发育的相关性方面，最近也取得了进展。这篇评论描述了我们目前对赤霉素代谢及其调控的理解，
