Abstract

Ustilaginoidea virens, the causative agent of rice false smut (RFS), has become a globally significant pathogen, infecting rice during the booting stage by targeting floral tissues and forming smut balls that reduce yield and grain quality. It also produces mycotoxins, posing health risks to humans and animals. Fungicide resistance and the pathogen's unique infection strategy complicate management, prompting intensified research into host-pathogen interactions and sustainable control measures. This review provides a comprehensive synthesis of the biology, infection dynamics, and host interactions of U. virens, focusing on its unconventional pathogenic mechanisms and the heightened vulnerability of rice floral tissues. It uniquely emphasizes host resistance's molecular and biochemical underpinnings, exploring how the pathogen modulates host pathways and how rice plants mount structural and chemical defenses. The review also discusses recent advances in genetic resistance, including QTL identification, resistance screening parameters, and the integration of resistance genes into breeding programs. By highlighting promising donor sources and outlining future research directions, this review serves as a critical resource for developing sustainable and targeted strategies to mitigate the RFS impact.

从侵染到抗性：稻曲病及其对水稻的影响综述

稻瘟病菌Ustilaginoidea virens是水稻假黑穗病（rice rice rice rice rice rice rice， RFS）的病原菌，在水稻孕穗期侵染水稻，以花组织为目标，形成黑穗病球，降低产量和籽粒品质。它还会产生真菌毒素，对人类和动物的健康构成威胁。杀菌剂耐药性和病原体独特的感染策略使管理复杂化，促使人们加强对宿主-病原体相互作用和可持续控制措施的研究。本文综述了该菌的生物学、感染动力学和寄主相互作用，重点介绍了其非常规致病机制和水稻花组织的高易感性。它独特地强调寄主抗性的分子和生化基础，探索病原体如何调节寄主途径以及水稻植物如何建立结构和化学防御。本文还讨论了遗传抗性的最新进展，包括QTL鉴定、抗性筛选参数和抗性基因整合到育种计划中。通过强调有希望的捐助来源和概述未来的研究方向，该审查是制定可持续和有针对性的战略以减轻可再生燃料标准影响的关键资源。

期刊介绍： Physiological and Molecular Plant Pathology provides an International forum for original research papers, reviews, and commentaries on all aspects of the molecular biology, biochemistry, physiology, histology and cytology, genetics and evolution of plant-microbe interactions. Papers on all kinds of infective pathogen, including viruses, prokaryotes, fungi, and nematodes, as well as mutualistic organisms such as Rhizobium and mycorrhyzal fungi, are acceptable as long as they have a bearing on the interaction between pathogen and plant.
