Abstract

Functional analysis of natural variation in the model species Arabidopsis thaliana has enabled the cloning of many glucosinolate biosynthesis and hydrolysis genes. Variation in these genes is central to understanding the ecological role of the glucosinolate-myrosinase defense system, and allows us to dissect the evolutionary and ecological forces that shape polymorphism at underlying loci. These same genes are also variable in other crucifer species, suggesting the presence of recurring selection, possibly mediated by insects. By utilizing the genomic tools available in A. thaliana to investigate these loci fully, it might be possible to generate detailed evolutionary or ecological models to apply to other species.

摘要

对模式植物拟南芥自然变异的功能分析，已使许多芥子油苷生物合成和水解基因得以克隆。这些基因的变异对于理解芥子油苷 - 黑芥子酶防御系统的生态作用至关重要，并且使我们能够剖析塑造潜在基因座多态性的进化和生态力量。这些相同的基因在其他十字花科物种中也存在变异，这表明可能存在反复的选择，可能是由昆虫介导的。通过利用拟南芥中可用的基因组工具来全面研究这些基因座，有可能生成详细的进化或生态模型以应用于其他物种。
