Plant-virus-host interaction is a complex process involving several players. A constant arms race between the hosts and viruses has led to their co-evolution. Reactive oxygen species (ROS) are important signaling molecules that regulate plant growth, development, and stress responses. Barley yellow dwarf virus (BYDV) has a wide host range and infects several plant species such as barley, rice, oats, wheat, etc. A recent study by Tian et al. (2024) has highlighted that the movement protein (MP) of BYDV is involved in manipulation of the host ROS pathway to promote viral multiplication as well as transmission. The findings display the multifaceted role of a viral protein that is otherwise involved in movement. The limited coding ability of viruses is compensated by their proteins having multiple roles in the modulation of several different host molecular pathways. This is one of the key reasons for viruses being successful pathogens despite their limited coding ability.
植物-病毒-宿主相互作用是一个复杂的过程，涉及到多个参与者。宿主和病毒之间的持续军备竞赛导致了它们的共同进化。活性氧（ROS）是调节植物生长、发育和应激反应的重要信号分子。大麦黄花叶病毒（BYDV）宿主范围广泛，感染多种植物，如大麦、水稻、燕麦、小麦等。最近 Tian 等人的研究（2024）强调，BYDV 的移动蛋白（MP）参与操纵宿主 ROS 途径，以促进病毒复制和传播。这些发现展示了病毒蛋白的多面性，该蛋白通常参与运动。病毒有限的编码能力通过其蛋白在调节多种不同宿主分子途径方面的多种作用得到补偿。这是病毒尽管编码能力有限，但仍能成为成功病原体的关键原因之一。
