Abstract

Grass inflorescences produce grains, which are directly connected to our food. In grass crops, yields are mainly affected by grain number and weight; thus, understanding inflorescence shape is crucially important for cereal crop breeding. In the last two decades, several key genes controlling inflorescence shape have been elucidated, thanks to the availability of rich genetic resources and powerful genomics tools. In this review, we focus on the inflorescence architecture of Triticeae species, including the major cereal crops wheat and barley. We summarize recent advances in our understanding of the genetic basis of spike branching, and spikelet and floret development in the Triticeae. Considering our changing climate and its impacts on cereal crop yields, we also discuss the future orientation of research.

在小麦科花序中,形式服从功能。
草的花序产生谷物,这些谷物与我们的食物直接相关。在禾草作物中,产量主要受粒数和重量的影响;因此,了解花序形状对谷类作物育种至关重要。在过去的二十年中,由于丰富的遗传资源和强大的基因组学工具的可用性,一些控制花序形状的关键基因已经被阐明。本文综述了小麦科植物的花序结构,包括主要的谷类作物小麦和大麦。本文综述了小麦科植物穗分枝的遗传基础以及小穗和小花发育的最新进展。考虑到气候变化及其对谷类作物产量的影响,我们还讨论了未来的研究方向。

期刊介绍: Breeding Science is published by the Japanese Society of Breeding. Breeding Science publishes research papers, notes and reviews related to breeding. Research Papers are standard original articles. Notes report new cultivars, breeding lines, germplasms, genetic stocks, mapping populations, database, software, and techniques significant and useful for breeding. Reviews summarize recent and historical events related breeding. Manuscripts should be submitted by corresponding author. Corresponding author must have obtained permission from all authors prior to submission. Correspondence, proofs, and charges of excess page and color figures should be handled by the corresponding author.
