本章介绍了如何更深入地了解植物的有性生殖，特别是减数分裂的过程，应导致更好地利用种质在作物育种作为应对气候变化。它解释了为什么减数分裂重组是产生新品种的核心。来自拟南芥的知识将通过旨在改变作物物种减数分裂重组的实验来实施和评估，最初使用密切相关的芸苔属和谷类作物大麦，总体目标是为植物育种者提供修改重组和潜在开发新品种的知识。
This chapter describes how a deeper understanding of sexual reproduction in plants, specifically the processes of meiosis, should lead to better use of germplasm in crop breeding as a response to climate change. It explains why meiotic recombination lies at the heart of generating novel varieties. Knowledge fromArabidopsis thalianawill be implemented and assessed by experiments aimed at altering meiotic recombination in crop species, initially using the closely related brassicas and the cereal crop barley, with the overall aim of providing the plant breeder with the knowledge to modify recombination and potentially develop new varieties.
