“…4a). This result is in accordance with the results of Tobacco mosaic virus infected tobacco (Lagrimini and Rothstein,1987), plum pox virus infected peaches, apricots (Diaz-Vivancos et al, 2006), Beans yellow mosaic virus infected beans (Radwan et al, 2010), Potato virus Y infected potato (Milavec et al, 2001), tomato and bell pepper infected with Tobacco mosaic virus and Tomato mosaic tobamo virus (Madhusudhan et al, 2009), Cucumber mosaic virus and Zucchini yellow mosaic virus infected Cucumis sativus and Cucurbita pepo plants ( Riedle-Bauer, 2000), Tobacco mosaic virus infected tobacco plants (Kiraly et al, 2002), Tomato yellow leaf curl virus infected tomato plants (Dieng et al, 2011), Banana bunchy top virus infected cultivars of banana (Devanathan et al, 2005), geminivirus infected Capsicum annum (Meena et al, 2008) and cotton with CLCuBuV (Siddique et al, 2014). Virus infection appears to stimulate POX activity in all hosts in (Wood, 1990).…”

“…The AOX is proposed to be responsible for chlorophyll degradation and POX levels increase during senescence (Kuroda et al, 1990). So, there is a correlation between the decrease in chlorophyll content and increase in POX activity in the green leaves infected with virus (Milavec et al, 2001). Also, POX is known to catalyze the final polymerization step of lignin synthesis and is directly associated with the increased ability of systemically protected tissues to lignify (Chittoor et al, 1999).…”

A B S T R A C TVirus infection can result in the alteration of physiological, biochemical and metabolic processes within plants leading to symptom development. Banana bunchy top virus (BBTV) is one of the most destructive viral diseases in Tropical Asia, Pacific Indian Oceania (PIO) regions and Africa leading to 100% yield loss in banana and plantains. Though molecular characterization and their diversity were studied in depth in recent years, information on physiological and biochemical changes during banana-BBTV interaction is still not convincingly explained. Therefore, the present investigation was conducted to find out the quantifiable changes in physiological and biochemical parameters such as proteins, pigment and carbohydrate content, phenolic compounds, polyphenol oxidase (PPO), peroxidase (POX), ascorbate peroxidase (APX), guaiacol peroxidase (GPX), catalase (CAT) and superoxide dismutase (SOD) activities in leaves of banana cultivars Grand Nain (AAA) and Virupakshi (AAB). The amount of carbohydrate contents, phenolic compounds, PPO, POX, APX, GPX, CAT were significantly higher in BBTV infected leaves of both the cultivars over the healthy, whereas total protein content, pigments and SOD activity showed an opposite trend. Overall the results suggest that BBTV infection induces significant changes in enzyme levels leading to irreversible symptom development. Further studies would lead to identification of biochemical markers for studying plant-virus compatible and incompatible interactions.

“…These results were opposite to data presented for other pathosystems. Milavec et al (2001) reported an inverse correlation between the chlorophyll content and the activity of soluble and ionic-bound peroxidases in 4-weeks old potatoes at 5-7 dpi with Potato virus Y. However, in our time-course study the decrease in the activity of soluble POX ( Figure 5) was found to correspond with the previously reported decrease in the content of chlorophylls and carotenoids (Kyseláková et al 2011).…”

(2013): Reactive oxygen and nitrogen species and hormone signalling in systemic infection of pea by Pea enation mosaic virus. Plant Protect. Sci., 49: 105-119.The physiological responses of pea plants during 40 days of compatible interaction with Pea enation mosaic virus (PEMV) were evaluated. PEMV induces systemic changes in the concentration of phytohormones. At 5 days post inoculation (dpi), a simultaneous increase in abscisic acid (ABA) level and a decrease in salicylic acid (SA) level was observed, which is known to be involved in the suppression of hypersensitive reaction. In our pathosystem it preceded the virus presence in the systemic leaves. PEMV induces the accumulation of ABA, SA and Hsp70 and enhances peroxidase (POX) activity at 15 dpi, when it is already transmitted throughout the plant. The formation of enations was preceded by a local accumulation of nitric oxide, which was followed by the appearance of reactive oxygen species, mostly in the vicinity of leaf veins. Such heterogeneity suggests involvement of these molecules in the control of hyperplasia and tissue differentiation.

“…Results of this study however, contrasts with those of White and Blakke (1992), who reported increased level of protein in barley infected with WSMV and BSMV separately. Milavec et al (2001) and Hemida (2005) have also documented increases in the protein content in potato-PVY NTN and Vicia faba-BYMV combination. Significant reductions in fibre and fat observed in this study is consistents with those of Mofunanya et al (2008) in T. occidentalis-TeMV combination andOwolabi et al (2010) in Ivy gourd-MWMV combination.…”

The reaction of Amaranthus hybridus to Telfairia mosaic virus (TeMV) infection was investigated. Infected and healthy (control) leaf samples were obtained, pulverized and analyzed to determine the nutritional quality of the vegetable due to TeMV infection. Results obtained revealed that the virus caused significant (p<0.05) reductions in fibre (50.9%), fat (49.7%) and protein (32.5%) in infected samples compared to healthy ones. The virus also engendered significant reductions in the contents of Na, P, Fe, Mg, Cu and Ca with marginal reduction for K in infected samples when compared to the healthy. The TeMV caused significant reduction in phytic acid while infection led to increases in total oxalate, soluble oxalate and hydrocyanide acid. The virus caused significant reductions (p<0.05) in vitamin A (55.43%), C (43.1%), B 1 (34.6%), B 2 (26.6%), B 6 (17.8%) and B 3 (13.1%), respectively while, reduction in vitamin E was insignificant. The reaction of amino acids profile of Amaranthus hybridus to TeMV infection revealed significance decrease in methionine (35.3%), valine (34.1%), cysteine (31.9%), arginine (26.1%), isoleucine (25.9%), glycine (22.8%), lysine (17.3%), threonine (15.0%), phenylalanine (12.1%) and leucine (11.8%). Increases in infected samples were obtained for glutamic acid (19.8%), aspartic acid (9.5%) and proline (8.9%). Amaranthus hybridus reaction to TeMV infection revealed marked reductions in the nutritional quality of the vegetable that is a major source of nutrient for both rural and urban dwellers.
