“…Mistletoe comes directly into contact with apple trees through haustoria, during which it may become systemically infected with ACFSVd and transmit the viroid from infected to uninfected trees [ 10 ]. Domesticated goats have been reported to transmit viroids when their horns were rubbed against viroid-infected trees [ 80 , 81 ]. Transmission via goats could have facilitated the long-range spread of viroids among cultivated and wild plants and vice versa, as well as among graft-incompatible plants.…”

Studies on the ways in which viroids are transmitted are important for understanding their epidemiology and for developing effective control measures for viroid diseases. Viroids may be spread via vegetative propagules, mechanical damage, seed, pollen, or biological vectors. Vegetative propagation is the most prevalent mode of spread at the global, national and local level while further dissemination can readily occur by mechanical transmission through crop handling with viroid-contaminated hands or pruning and harvesting tools. The current knowledge of seed and pollen transmission of viroids in different crops is described. Biological vectors shown to transmit viroids include certain insects, parasitic plants, and goats. Under laboratory conditions, viroids were also shown to replicate in and be transmitted by phytopathogenic ascomycete fungi; therefore, fungi possibly serve as biological vectors of viroids in nature. The term “mycoviroids or fungal viroids” has been introduced in order to denote these viroids. Experimentally, known sequence variants of viroids can be transmitted as recombinant infectious cDNA clones or transcripts. In this review, we endeavor to provide a comprehensive overview of the modes of viroid transmission under both natural and experimental situations. A special focus is the key findings which can be applied to the control of viroid diseases.

“…The PLMVd infection was initially thought to be restricted to Prunus spp., where the incidence and economic impact may be remarkable in distinct parts of the world (Di Serio et al, 1999;Flores et al, 2003;. In the last years the viroid has been detected in other fruit trees including apricot, plum, sweet cherry, pear and mango and, also, in grapevine (Kyriakopoulou et al, 2017). In addition, PLMVd infection in kaki and Johnsongrass has been recently reported (Oksal et al, 2021).…”

“…Further, HSVd (hop stunt viroid) and CEVd (citrus exocortis viroid) viroid transmission has been reported due to domesticated goats (Capra hircus) and additionally when the horns of these goats rubbed against trees that are infected with viroids such as PLMVd [36,37].Such goat-mediated transmission could have resulted in long-range dissemination of viroids amongst wild and cultivated plants and reciprocally in addition to amongst plants that are graft-incompatible.…”

Plant diseases are responsible for over 10% loss in global food production and have serious impacts on world-wide food security across several countries. Amongst these diseases, those caused by viroids are highly significant, accounting for extensive damage to crops every year and pose a major economic threat to agricultural crops. Combined infections with viroids, plant viruses and their satellites further exacerbate the situation. Vector transmission of viroids necessitates the use of pesticides, thus incurring high costs in addition to eliciting several detrimental effects on the ecosystem due to the noxious outcomes of pesticide use. The current review addresses the major economic impacts of viroids on crops, costs to the world economy and impacts on regions, farmers and consumers in addition to describing remediation measures to mitigate the losses caused by these subviral agents. Also described are issues relating to the pros and cons of pesticide use, the compelling need towards sustainable agricultrual practices while reducing pesticide use. In particular, the role of RNAi and genome editing technologies towards amelioration of agricultural loss is discussed.
