Sida Golden Mosaic Virus, an Emerging Pathogen of Snap Bean (Phaseolus vulgaris L.) in the Southeastern United States

Sida golden mosaic virus (SiGMV) was first detected from snap bean (Phaseolus vulgaris L.) in Florida in 2006 and recently in Georgia in 2018. Since 2018, it has caused significant economic losses to snap bean growers in Georgia. This study, using a SiGMV isolate field-collected from prickly sida (S...

description Sida golden mosaic virus (SiGMV) was first detected from snap bean (Phaseolus vulgaris L.) in Florida in 2006 and recently in Georgia in 2018. Since 2018, it has caused significant economic losses to snap bean growers in Georgia. This study, using a SiGMV isolate field-collected from prickly sida (Sida spinosa L.), examined the putative host range, vector-mediated transmission, and SiGMV-modulated effects on host–vector interactions. In addition, this study analyzed the phylogenetic relationships of SiGMV with other begomoviruses reported from Sida spp. Host range studies confirmed that SiGMV can infect seasonal crops and perennial weed species such as snap bean, hollyhock (Alcea rosea L.), marsh mallow (Althaea officinalis L.), okra (Abelmoschus esculentus (L.) Moench), country mallow (Sida cordifolia L.), prickly sida (S. spinosa), and tobacco (Nicotiana tabacum L.). The incidence of infection ranged from 70 to 100%. SiGMV-induced symptoms and virus accumulation varied between hosts. The vector, Bemisia tabaci Gennadius, was able to complete its life cycle on all plant species, irrespective of SiGMV infection status. However, SiGMV infection in prickly sida and country mallow positively increased the fitness of whiteflies, whereas SiGMV infection in okra negatively influenced whitefly fitness. Whiteflies efficiently back-transmitted SiGMV from infected prickly sida, hollyhock, marsh mallow, and okra to snap bean, and the incidence of infection ranged from 27 to 80%. Complete DNA-A sequence from this study shared 97% identity with SiGMV sequences reported from Florida and it was determined to be closely related with sida viruses reported from the New World. These results suggest that SiGMV, a New World begomovirus, has a broad host range that would allow its establishment in the farmscapes/landscapes of the southeastern United States and is an emerging threat to snap bean and possibly other crops.
