“…Superoxide dismutase: Superoxide dismutase is one of the most important scavenging enzymes and catalyzes the dismutation of superoxide radicals to active oxygen species hydrogen peroxide (Ehsani-Moghaddam et al, 2006;Hameed and Iqbal, 2014). The SOD activity was significantly higher in leaves of healthy plants of both the cultivars (Fig.…”

“…This is in agreement with results of Hernandez et al (2004), who has observed a significant decrease in SOD from Plum pox virus inoculated peaches, similarly Clarke et al (2002) in WClMV-infected Phaseolus vulgaris L., plants, Buonaurio and Montalbini (1993) in case of PVY infected tobacco plants, Ashfaq et al (2010) in Urdbean leaf crikle virus (ULCV) infected black gram and Zhuang et al (1993) in a resistant soybean infected with Soybean mosaic virus. Higher activity of SOD could be a strategy of the plant to restrict virus colonization, because the excess ROS can be removed (Govrin and Levine, 2000;Ehsani-Moghaddam et al, 2006) and vice versa when SOD was lower resulting in oxidative stress.…”

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.

“…Antioxidant level in plants and activities of ROS scavenging enzymes have been reported to be correlated with tolerance to different environmental stresses (Chaitanya et al 2002) including diseases (Ehsani-Moghaddam et al 2006) and agronomic factors (Novarro et al 2006). When plants are damaged they produce cytotoxic activated oxygen, which can disrupt normal metabolism through oxidative damage of lipids, proteins, and nucleic acids.…”

The present study was carried out to estimate the crude, hydrophilic and lipophilic antioxidant content of known and new advanced selections among June-bearing and day-neutral genotypes using Trolox equivalent antioxidant capacity method. Crude, hydrophilic and lipophilic extractions were prepared using 25 g of frozen fruits from each sample. In June-bearing strawberries, significant differences were observed among crude, hydrophilic and lipophilic antioxidant values of different selected genotypes. Mean of crude, hydrophilic and lipophilic antioxidants in June-bearings were estimated to be 20.4, 13.4 and 0.5 µmol TE g -1 FW, respectively, which were higher than those of the day-neutral genotypes (i.e., 13.2, 9.4 and 0.3 µmol TE g -1 FW). The present study revealed the importance of genetic background for determining the antioxidant potential in selected June-bearing genotypes and the possibility of production of new strawberry cultivars with higher levels of antioxidant capacity through breeding programs.

The effect of leaf infection by the fungus Mycosphaerella fragariae, on total superoxide dismutase activity and induction of SOD isozymes was studied under controlled conditions using four selected strawberry cultivars: Kent (HS, highly susceptible), Joliette (HR, highly resistant) and two advanced strawberry lines, SJ8976-1 and APF029-4 (MR, moderately resistant). Observations were made of conidia morphology of M. fragariae grown in strawberry leaf agar (SLA) at different stages of conidia development and of infective symptoms of the leaves after inoculation. Inoculation of strawberry leaves with M. fragariae increased protein content and SOD activities in all four cultivars. In all cases, total SOD increased 1 day (d) after inoculation, reaching a peak 2 d after inoculation, and slowly declining thereafter. Total SOD activity in Joliette, SJ8976-1 and APF029-4 two days after inoculation was 4376, 4433 and 4283 U g -1 FW, respectively, and significantly was lower for Kent (3656 U g -1 FW). From the electrophoresis profile of the strawberry cultivars, 2 newly synthesized isozymes were found in infected Joliette and SJ8976-1, (R f = 0.31 and 0.34), which are believed to be associated with leaf spot resistance.
