Abstract

Increasing agricultural losses caused by insect infestations are a significant problem, so it is important to generate pest-resistant crop varieties to address this issue. Several reviews have examined aphid–plant interactions from an entomological perspective. However, few have specifically focused on plant resistance mechanisms to aphids and their applications in breeding for aphid resistance. In this review, we first outline the types of resistance to aphids in plants, namely antixenosis, tolerance (cell wall lignification, resistance proteins), and antibiosis, and we discuss strategies based on each of these resistance mechanisms to generate plant varieties with improved resistance. We then outline research on the complex interactions among plants, viruses, and aphids, and discuss how aspects of these interactions can be exploited to improve aphid resistance. A deeper understanding of the epigenetic mechanisms related to induced resistance, i.e., the phenomenon where plants become more resistant to a stress they have encountered previously, may allow for its exploitation in breeding for aphid resistance. Wild relatives of crop plants serve as important sources of resistance traits. Genes related to these traits can be introduced into cultivated crop varieties by breeding or genetic modification, and de novo domestication of wild varieties can be used to exploit multiple excellent characteristics, including aphid resistance. Finally, we discuss the use of molecular design breeding, genomic data, and gene editing to generate new aphid-resistant, high-quality crop varieties.

增强园艺作物的抗蚜性：育种展望

虫害造成的农业损失不断增加是一个重大问题，因此必须培育抗虫害作物品种来解决这一问题。一些综述从昆虫学的角度研究了蚜虫与植物之间的相互作用。然而，很少有综述特别关注植物对蚜虫的抗性机制及其在抗蚜育种中的应用。在这篇综述中，我们首先概述了植物对蚜虫的抗性类型，即抗蚜性、耐受性（细胞壁木质化、抗性蛋白）和抗生物性，并讨论了基于每种抗性机制培育具有更强抗性的植物品种的策略。然后，我们概述了有关植物、病毒和蚜虫之间复杂相互作用的研究，并讨论了如何利用这些相互作用的各个方面来提高蚜虫的抗性。深入了解与诱导抗性相关的表观遗传学机制（即植物对之前遇到的压力具有更强抗性的现象），可以在培育抗蚜品种时加以利用。作物的野生近缘植物是抗性特征的重要来源。与这些性状相关的基因可通过育种或基因改造引入栽培作物品种，而野生品种的全新驯化可用于利用包括抗蚜性在内的多种优良特性。最后，我们将讨论如何利用分子设计育种、基因组数据和基因编辑来培育抗蚜虫的优质农作物新品种。
