摘要/Abstract

摘要：

自170多年前爱尔兰大饥荒爆发以来，由致病疫霉（Phytophthora infestans）危害导致的晚疫病一直是全球马铃薯产业中最严重的威胁之一，每年造成的产量损失与防治成本以百亿美元计，该病害也位列我国7种一类农作物病害之一。经过过去数十年的不懈研究，研究人员在晚疫病的致病分子机制与田间防控策略等方面已取得了一些重要进展。然而，为满足我国农业减药增效的国家需求，如何确保绿色、高效、可持续的晚疫病防治已成为推进马铃薯产业发展所必须解决的技术问题。本文简要概括了当前马铃薯-致病疫霉分子互作领域的研究进展，总结了从地区微观到大陆宏观尺度上晚疫病防治策略，并探讨了未来作物抗性遗传改良与新型植保技术在晚疫病可持续治理中的作用。

Abstract:

Over 170 years after the infamous Irish Potato Famine, potato late blight (PLB) caused by Phytophthora infestans remains the single most devastating disease of global potato production, causing up to 10 billion USD in yield loss and management costs. Through decades of research, growers and agronomists in the field as well as laboratory scientists have made significant progress in understanding the molecular pathogenesis process of this critical pathosystem and effective management strategies to control PLB. Yet, the need to feed an ever-increasing global population under changing climate demands continued improvement in efficient and sustainable PLB management schemes that can be implemented across a broad economic spectrum. In this review, we briefly summarize the current understanding of the molecular interaction between P. infestans and its host plants, highlight the current integrated pest management strategy to control PLB on local and continental scales, and discuss the potential of further improvement of sustainable PLB control through genetic enhancement of crop resistance and emerging crop protection technologies.
