“…Verhoeven et al [ 27 ] reported transmission of PCFVd for 11 out of 59 seedlings. However, Verhoeven et al [ 31 ] were not able to confirm the previously reported seed transmission for PCFVd in 179 seedlings of the same pepper variety and 158 seedlings of another variety. In addition, no seed transmission of PCFVd was reported in 46 seedlings by Yanagisawa and Matsushita [ 32 ].…”

“…For PSTVd, Matsushita and Tsuda [ 33 ] reported transmission for seven out of 2230 seedlings. In contrast, no seed transmission was reported by Lebas et al [ 34 ] and by Verhoeven et al [ 31 ] for 25 and 222 pepper seedlings. With regard to the other pospiviroids, no seed transmission was reported for columnea latent viroid (CLVd) [ 31 ], TASVd [ 31 ], TCDVd [ 33 ], and tomato planta macho viroid (TPMVd) [ 32 ], based on examination of 179, 217, 1105, and 46 seedlings, respectively.…”

“…Although the rate of seed transmission may be affected by the viroid variant, (a cultivar of) the host plant and environmental conditions, the substantially higher seed-transmission rates reported for experimentally produced seeds ( Table 3 and Table 5 ) raised the question of whether the industrial seed processing also may affect the transmission from seed to seedling. For pepper seeds, Verhoeven et al [ 31 ] did not find such an effect, when simulating industrial processing by postponing the date of sowing. Neither does industrial processing seem to abolish the viability of the viroids of infested seeds.…”

Several outbreaks of pospiviroids have been reported in pepper and tomato crops worldwide. Tracing back the origin of the infections has led to different sources. In some cases, the infections were considered to result from seed transmission. Other outbreaks were related to transmission from ornamental crops and weeds. Pospiviroids, in particular potato spindle tuber viroid, are regulated by many countries because they can be harmful to potatoes and tomatoes. Seed transmission has been considered an important pathway of introduction and spread. However, the importance of this pathway can be questioned. This paper presents data on seed transmission from large-scale grow-out trials of infested pepper and tomato seed lots produced under standard seed-industry conditions. In addition, it presents the results of a systematic review of published data on seed transmission and outbreaks in commercial pepper and tomato crops. Based on the results of the grow-out trials and review of the literature, it was concluded that the role of seed transmission in the spread of pospiviroids in practice is possibly overestimated.

First report of potato spindle tuber viroid isolated from pepper seeds produced in Vietnam

Potato spindle tuber viroid (PSTVd; genus Pospiviroid) was detected from pepper (Capsicum annuum) seeds produced in Vietnam, during an export inspection. The PSTVd isolate maintained its viability. To investigate the phylogenetic relationship between PSTVd-VN and other PSTVd variants isolated from other plants, the PSTVd isolate was classi ed into lethal and severe strains. Inoculated tomatoes (cv.Rutgers) caused severe stunting, with necrosis of the stems and leaf veins. Although the inoculated pepper plants were asymptomatic, the fruits were smaller than the healthy ones. To our knowledge, this is the rst report of PSTVd from pepper seeds produced in Vietnam. Full TextViroids are unencapsidated, single-stranded, circular RNA consisting of 246-401 nucleotides. Among plant pathogens, they are the smallest pathogens and belong to two families (Pospiviroidae and Avsunviroidae) (Flores et al. 2005). The genus Pospiviroid in the family Pospiviroidae consists of nine species, of which one is the potato spindle tuber viroid (PSTVd) (Full ICTV Report on the Genus Pospiviroid; https://ictv.global/report/chapter/pospiviroidae/pospiviroidae/pospiviroid).Although PSTVd was originally reported in North America, it has spread to Africa, Asia, Europe, and South America (Smith et al. 1997). In recent years, PSTVd has been identi ed in several countries, and new viroids are being continuously discovered (Kinoga et al. 2021;Matsushita et al. 2021;Sial and Khan 2018).PSTVd infects various host plants and causes stunting, leaf chlorosis, leaf epinasty, fruit distortion, and stem and leaf necrosis in tomatoes (Solanum lycopersicum) and potatoes (S. tuberosum) (Hadidi et al. 2003;Singh et al. 2003). Viroids spread mechanically through plant sap, grafting, and transmission through seeds and pollen (Matsushita et al. 2018). Among these, seed transmission is an important
