传统上，通过收集种子作物的长期观测数据并将种子与环境变量相关联来研究桅杆播种的机制。生态基因组学的重大进展将通过阐明肥大性状的遗传基础和自然选择在塑造这些性状中的作用，提高我们对肥大进化的理解。在这里，我们总结了在遗传水平上研究肥大的进化的三个重要方面：哪些性状支配肥大，这些性状是否是遗传调控的，以及哪些类群在这些性状上表现出广泛的变异。然后，我们介绍了最近的研究的分子机制的masting。这些研究测量了自然条件下基因表达的季节性变化，以量化多种环境因素如何结合联合收割机来调节花的开始，这在许多主枝植物物种中是种子作物两年变化的最大贡献者。我们表明，壳斗科提供了特殊的机会，因为它的多样性在表型和遗传水平和现有的记录基因组序列的进化调查。这篇文章是“植物同步种子生产的生态学和进化”主题的一部分。
The mechanisms underlying mast seeding have traditionally been studied by collecting long-term observational data on seed crops and correlating seedfall with environmental variables. Significant progress in ecological genomics will improve our understanding of the evolution of masting by clarifying the genetic basis of masting traits and the role of natural selection in shaping those traits. Here, we summarize three important aspects in studying the evolution of masting at the genetic level: which traits govern masting, whether those traits are genetically regulated, and which taxa show wide variation in these traits. We then introduce recent studies on the molecular mechanisms of masting. Those studies measure seasonal changes in gene expression in natural conditions to quantify how multiple environmental factors combine to regulate floral initiation, which in many masting plant species is the single largest contributor to among-year variation in seed crops. We show that Fagaceae offers exceptional opportunities for evolutionary investigations because of its diversity at both the phenotypic and genetic levels and existing documented genome sequences. This article is part of the theme issue ‘The ecology and evolution of synchronized seed production in plants’.
