“…Major symptoms of PVY in potato include mild mosaic on leaves and necrosis of leaves and tubers. Yield losses due to PVY infections are between 40 and 70 % [20]. The genome of PVY consists of a ?ssRNA of *10 kb containing an open reading frame (ORF) encoding a single polyprotein precursor of 350 kDa [33].…”

Potato virus Y (PVY) and potato virus X (PVX), the RNA viruses of two different genera results into synergistic interactions on mixed infection. In this study, a N-Wi strain of PVY and a PVX strain that is asymptomatic on potato were used to study their interactions during mixed infection in Nicotiana benthamiana and Nicotiana tabacum with reference to symptom expression, level of coat protein (CP) using ELISA and suppressor gene using real time PCR under high temperature (26-40°C) and low temperature (5-25°C) conditions. Both mixed and single infection caused severe necrosis and death of N. benthamiana plants. Single infection of these viruses in N. tabacum showed mild symptoms but mixed infection caused more severe symptoms. Synergistic symptoms were more pronounced under low temperature conditions than at high temperature. In low temperature conditions, the CP level of PVX in N. benthamiana was twofold higher than PVY and both the viruses reached at peak at 28 dpi in single virus infection. When PVY and PVX inoculated together, the CP levels of both the viruses increased and reached to the peak earlier (within 7-14 days) than that in the single virus inoculation. Although, the CP level of PVX was higher than PVY in mixed infection, at later stage (28 dpi) both the CP level declined to the similar level. The level of p25 suppressor gene was higher than HCPro in single inoculation. However, under mixed inoculation of PVY and PVX, expression of p25 was declined to the level of HC-Pro when the CP levels of both the virus also were observed to decline. The expression pattern of CP and suppressor gene was different in plants when mixed infection was created by inoculation of one virus followed by the other. This study showed the level of CP and suppressor gene of specific strain of PVY and PVX during their mixed infection in tobacco.

“…PVX is transmitted through contact. It causes mild mottle mosaic symptoms in potato and accounts for 15-30 % yield losses [3,20]. The PVX genome contains a large 5 0 ORF-1 coding for the 65K protein, a putative component for RNA replication and it is translated directly from genomic RNA [24,38].…”

“…The disease is also managed through seed treatment with benomyl, carbendazim, thiabendazole, pencycuron, penflufen 240 FS and Thiophinate methyl 45%+ pyaclostrobin 5 % FS (Banyal, 2002;Thind et al, 2002;Lal et al, 2014;Lal et al, 2016). Two chemicals viz., Boric acid and Pencycuron are frequently used by Indian farmers to management black scurf of potato (Khurana et al, 2001). Thifluzamide is comes under the chemical group of Thiazolecarboxamides and its target site is Succinate dehydrogease complex II in respiratory chain and affect the fungal respiration (FRAC, 2017).…”

“…During the primary infection, the seed tubers are asymptomatic, but symptoms become visible at secondary stage (Chatzivassiliou, 2008). PLRV causes a prominent upright characteristic rolling, chlorosis or reddening, and roughness in the texture of potato plant leaves (Khurana, 2004). The PLRV infected plant remains stunted in growth producing reduced number and size of tubers (Nawres, 2013 (Dabijev et al, 2005;Kerlan, 2009;Kostiw, 2011).…”

Polerovirus: potato leaf roll virus (PLRV), Potyvirus: potato virus Y (PVY) and Potexvirus: potato virus X (PVX) is more destructive and well distributed throughout the Pakistan. Incidence has been reported to be as high as 90%, 25%, and ≥ 15%, respectively in the potato growing regions. To find out the source of resistance, twenty-nine virus free potato varieties were grown under field conditions with good agricultural practices. The disease severity of PLRV, PVY and PVX was recorded to determine the level of resistance of the potato varieties according to the disease rating scale. Infectivity and biological assay of all twenty-nine varieties were done in green house on potato, Datura stramonium, Nicotiana glutinosa and Physalis floridana. Non-inoculated plants were served as control. Leaf samples from potato varieties were collected for serological detection of PLRV, PVY and PVX by Double antibody sandwich Enzyme-Linked Immunosorbent Assay (DAS-ELISA). Out of twenty nine varieties, none of the variety was resistant to PLRV although three varieties; Mirrato, 394021-120 and Orla were moderately resistant. Only FD 48-4 and TPS 9813 showed resistance to PVX and PVY. While FD 3-10, FD 9616 and FD 37-13 were moderately to PVX and PVY. Rest of the varieties was found susceptible to all three viruses.
