In general, symptoms of GBNV infection, which include chlorosis, mottle, lesions, stunted growth, necrotic rings, and bud necrosis, are very similar regardless of the infected host or virus isolate (Mandal et al., 2012).
In peanut: "Initially, mild chlorotic spots appear on young quadrifoliate leaves, and subsequently necrosis and chlorotic rings develop. In rainy and post-rainy seasons, necrosis of the terminal bud is the main characteristic symptom. Secondary symptoms such as stunting, axillary shoot proliferation, and malformation of leaflets are common. Plants infected early are bushy, stunted, and die prematurely. If plants older than one month are infected, the symptoms are restricted to a few branches only" (Mandal et al., 2012).
In tomato: Symptoms include necrotic rings on leaf, stem necrosis, concentric rings and patchy color on fruit (Manjunatha, 2008; Mandal et al., 2012). Necrosis of the foliage often leads to collapse of a stem or of the whole plant resembling symptoms of blight. In general, tomato plants infected at an early stage often collapse and die. (Akram et al., 2012).
In potato: Symptoms of infection are characterized by stem/petiole necrosis, foliar spotting/deformation/necrosis and stunting of the plant (Kaushal et al., 2010). Necrosis of foliage often leads to collapse of a stem or the entire plant. In general, potato plants infected at an early stage often collapse and die. (Akram et al., 2012; Pundhir et al., 2012).
In bean, pea, and other legumes: GBNV infection induces chlorotic and necrotic spots on leaves, browning in veins, stem necrosis, ring spots on fruits and pods (Akram et al., 2012).
