花序结构的改变对于小麦和大麦的成功驯化至关重要，小麦和大麦是小麦族的核心成员，为人类饮食提供必需的谷物。对支持驯化相关性状的基因和等位基因的研究为小麦族花序发育的分子调控提供了有价值的见解，并且对结构修饰形式的进一步研究也被证明同样富有成效。所鉴定的基因参与多种生物过程，包括转录调控、激素生物合成和代谢、转录后和翻译后调控，其通过改变侧部器官（称为小穗和小花）的发育和育性来改变花序结构。测序能力和突变群体的产生的最新进展正在加速影响花序发育的基因的鉴定，这是重要的，因为这种性状的遗传变异有望成为优化粮食生产的宝贵资源。这篇综述评估了我们对小麦和大麦花序发育基因的理解的最新进展，目的是强调发育生物学改进对优化主要作物植物农艺性状的重要性。本文综述了小麦族（包括主要作物小麦和大麦）花序构型遗传调控的研究进展。我们专注于驯化相关的关键性状，以及最近的研究，已使用修改形式的花序结构，以确定调控小穗和小花发育的基因。
Modifications of inflorescence architecture have been crucial for the successful domestication of wheat and barley, which are central members of the Triticeae tribe that provide essential grains for the human diet. Investigation of the genes and alleles that underpin domestication‐related traits has provided valuable insights into the molecular regulation of inflorescence development of the Triticeae, and further investigation of modified forms of architecture are proving to be equally fruitful. The identified genes are involved in diverse biological processes, including transcriptional regulation, hormone biosynthesis and metabolism, post‐transcriptional and post‐translational regulation, which alter inflorescence architecture by modifying the development and fertility of lateral organs, called spikelets and florets. Recent advances in sequencing capabilities and the generation of mutant populations are accelerating the identification of genes that influence inflorescence development, which is important given that genetic variation for this trait promises to be a valuable resource for optimizing grain production. This review assesses recent advances in our understanding of the genes controlling inflorescence development in wheat and barley, with the aim of highlighting the importance of improvements in developmental biology for optimizing the agronomic performance of staple crop plants. This review summarizes the recent advances on the genetic regulation of inflorescence architecture in the Triticeae tribe, including the staple crops of wheat and barley. We focus on the key domestication related traits, and recent studies that have used modified forms of inflorescence architecture to identify genes regulating spikelet and floret development.
