“…This can be exemplified with the issue of diagnosing cotton leaf roll dwarf disease (CLRDD) in the US, which is caused by a variant of CLRDV, due to the symptom similarity with bronze wilt disease (19). Furthermore, the cotton aphid is a known vector of a multitude of other viruses in Polerovirus and other viral genera such as Potyvirus and Mandarivirus (20)(21)(22). Therefore, even with the matching broad symptomology and aphid transmission, these factors alone are not definitive in concluding on the shared etiological agent.…”

“…Since it was first recognized in Yunnan Province, China, in 2009 (Chen et al, 2014 ), CYVCV has been reported in all major citrus‐growing provinces of China. It is easily transmitted by grafting, contaminated tools, Dialeurodes citri , and several aphid species (Afloukou et al, 2021 ; Zhang et al, 2018 ; Zhang, Liu, Wang, Wang, He, et al, 2019 ; Zhang, Liu, Wang, Wang, Zhou, & Zhou, 2019 ). Currently, CYVCV is considered the most important virus affecting lemon production in China (Wang, 2022 ).…”

Citrus yellow vein clearing virus (CYVCV) is an emerging virus that causes serious economic damage to the lemon industry worldwide. The coat protein (CP) of CYVCV is a strong RNA silencing suppressor and is associated with the severity of symptoms in citrus, yet the interaction between CP and host factors remains unknown. In this study, the 40S ribosomal subunit protein S9‐2 (ClRPS9‐2) was identified as a CP‐binding partner using the yeast two‐hybrid system from a lemon (cv. Eureka) cDNA library, and the interaction between CP and ClRPS9‐2 was demonstrated by in vivo methods. The results suggest that the N‐terminal 8–108 amino acid sequence of ClRPS9‐2 is crucial for its interaction with CP and may be associated with the nuclear localization of ClRPS9‐2. The accumulation and silencing suppressor activity of CP were reduced by transient expression of ClRPS9‐2 in Nicotiana benthamiana. Reverse transcription‐quantitative PCR analysis showed that the content of CYVCV in ClRPS9‐2 transgenic Eureka lemon plants was approximately 50% of that in CYVCV‐infected wild‐type plants 1 month after inoculation, and mild yellowing and vein clearing symptoms were observed in the transgenic plants. These findings demonstrate that ClRPS9‐2 plays a role in host defensive reactions, and the enhanced resistance of transgenic plants to CYVCV may be associated with the up‐regulation of salicylic acid‐related and R genes.

“…It caused particularly serious damage, resulting in reduced tree vigor, lower yields, and decreased marketability of fruit production. and it is easily transmitted by grafting, contaminated tools, Dialeurodes citri, and several aphid species ( Zhang et al., 2018 ; Zhang, et al., 2019 ; Afloukou et al., 2021 ), which may further make the spread of the disease quick and extensive. Therefore, it is necessary to pay attention to the virus and exploit useful methods to control this virus.…”

Reactive oxygen species (ROS) are closely related to the antiviral immune response of plants, while virus can regulate ROS through various pathways to facilitate their own infection or replication. Citrus yellow vein clearing virus (CYVCV) is one of the most devastating viruses affecting lemon (Citrus limon) industry worldwide. However, the pathogenesis of CYVCV remains poorly understood. In this study, direct interaction between the coat protein (CP) of CYVCV and the ascorbate peroxidase 1 of lemon (ClAPX1) was confirmed for the first time by yeast two-hybrid, Bimolecular Fluorescence Complementation, and Co-immunoprecipitation assays. Transient expression of CP in lemon and Nicotiana benthamiana significantly enhanced the enzyme activity of the ClAPX1, and then inhibited the accumulation of H2O2. In addition, overexpression of ClAPX1 in lemon by transgene significantly promoted CYVCV accumulation and depressed the expression of most genes involved in jasmonic acid (JA) signaling pathway. Correspondingly, ClAPX1 silencing by RNA interference inhibited CYVCV accumulation and increased the expression of most genes involved in JA signaling pathway. To our knowledge, this is the first report that viruses regulate ROS by targeting APX directly, thereby suppressing host immune response and promoting viral accumulation, which may be mediated by JA signaling pathway.
