“…SOD activity following PMeV with SNP was the highest measured at each time point, and was significantly different from each treatment overall (p<0.05). This is consistent with previous reports that show that virus infection can induce SOD activity [50,51].…”

Seedlings of papaya (Carica papaya), cultivar Golden, were exposed to a nitric oxide donor, sodium nitroprusside (SNP), Papaya meleira virus (PMeV) and yeast (Saccharomyces cerevisiae, as a model fungal elicitor). The aim was to investigate the response of C. papaya to infection and the role of nitric oxide in this process. SNP alone led to a short lived (6 h) burst of peroxidase activity and a relatively low level thereafter, although higher than the control, whilst the virus PMeV caused a sustained increase for at least 30 days. In contrast, both SNP and PMeV treatments increased superoxide dismutase activity for at least 30 days. In general, concomitant addition of PMeV and SNP produced the highest increases in peroxidase and superoxide dismutase activity over the 30 day time course. Levels of phenolics were elevated after addition of SNP and histochemistry confirmed increased peroxidase and superoxide dismutase activity, especially around the phloem cell walls, suggestive of lignification. Carbohydrate content was also elevated after SNP treatment, in particular saccharose. Treatment with yeast produced increased peroxidase activity and phenolic and carbohydrate content in the plant tissues. These results demonstrate some of the defences elicited in Carica papaya in response to infection, and the role of nitric oxide in this process. The apparent systemic acquired resistance displayed suggests that artificial initiation of this process might be a useful future technique against PMeV in the horticultural industry.

“…Singlet oxygen (O 2 1 ) is a potent agent of oxidative damage that could also contribute to chlorotic symptom development (Fryer et al, 2002). The BBTV infection could in turn increases ROS generation in other cellular compartments (Diaz-Vivancos et al, 2008;Song et al, 2009) in association with respiratory and photorespiratory processes. These alternative ROS sources might contribute to the development of chlorotic symptoms.…”

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.

“…Cucumber mosaic virus (CMV), the most important cucumovirus studied, infects important crop species such as tomato, celery, pepper and cucumber, producing important economic losses [140] by affecting vital metabolic processes such as photosynthesis and respiration [21,140]. In that respect, long-term CMV-infection produced a strong decrease in net photosynthesis rate in cucumber and tomato plants, that correlated with a significant reduction in qP and Y(II) chlorophyll fluorescence parameters [140].…”

a b s t r a c tDuring plantevirus interactions, defence responses are linked to the accumulation of reactive oxygen species (ROS). Importantly, ROS play a dual role by (1) eliciting pathogen restriction and often localized death of host plant cells at infection sites and (2) as a diffusible signal that induces antioxidant and pathogenesis-related defence responses in adjacent plant cells. The outcome of these defences largely depends on the speed of host responses including early ROS accumulation at virus infection sites. Rapid host reactions may result in early virus elimination without any oxidative stress (i.e. a symptomless, extreme resistance). A slower host response allows a certain degree of virus replication and movement resulting in oxidative stress and programmed death of affected plant cells before conferring pathogen arrest (hypersensitive response, HR). On the other hand, delayed host attempts to elicit virus resistance result in an imbalance of antioxidative metabolism and massively stressed systemic plant tissues (e.g. systemic chlorotic or necrotic symptoms). The final consequence of these processes is a partial or almost complete loss of control over virus invasion (compatible infections).
