Plant pathogens, including viruses, have a known negative impact on plant growth and development. Here, plant diseases caused by cactus virus X (CVX) are reviewed. CVX infects a range of plant species within the Cactaceae family. When expressed, symptoms include chlorosis, necrosis, and morphological alterations, such as the twisting of arms, but at times plants can be asymptomatic. CVX may be transmitted through contaminated grafting or cutting tools and can also occur as mixed infections with other viruses, including zygocactus virus X and pitaya virus X. CVX may also play a role in altering the plant's physiology. The virus can be detected by molecular assays, including polymerase chain reaction (PCR), and transmitted to indicator plants. Sanitation in both nurseries and fields is critical in controlling the spread of CVX. This paper highlights CVX as a potential production threat to some Cactaceae family members, particularly the now popular Hylocereus species or dragon fruits.

已知包括病毒在内的植物病原体会对植物的生长发育产生负面影响。在这里，回顾了由仙人掌病毒X（CVX）引起的植物病害。CVX感染了仙人掌科中的一系列植物。当表达时，症状包括萎黄，坏死和形态变化，例如手臂弯曲，但有时植物可能是无症状的。CVX可能通过受污染的嫁接工具或切割工具传播，也可能与其他病毒（包括仙人掌X和火龙果X病毒）混合感染而发生。CVX还可能在改变植物的生理过程中发挥作用。可以通过分子分析（包括聚合酶链反应（PCR））检测病毒，并将其传播给指示植物。苗圃和田间的卫生设施对于控制CVX的传播至关重要。本文重点介绍了CVX对某些仙人掌科成员的潜在生产威胁，特别是现在流行的Hylocereus物种或火龙果。
