“…Thus, if vectors are less successful in transmitting BBTV in a field environment, their overall impact on yield could significantly differ from what would be predicted from laboratory findings. It is not uncommon for virus infection to have a negative impact on plants by limiting their growth (Wilfert Eckel & Lampert, 1993;Miteva et al, 2005). However, to our knowledge, this is the first study to compare morphological and growth characteristics between BBTV-infected and healthy control banana plants.…”

Field experiments were conducted in Oahu, Hawaii, to investigate the effects of banana bunchy top virus (BBTV) infection on growth and morphology of banana (Musa acuminata). The time interval between aphid inoculation of BBTV and the initial appearance of disease symptoms (i.e. incubation period) was also determined. Plants infected with BBTV showed a significant reduction in petiole size (i.e. length and distance), plant canopy and height, leaf area, pseudostem diameter and chlorophyll content compared with control plants. Growth differences between virus-infected and control plants were not observed until 40-50 days after the plants were inoculated with viruliferous aphids. Other growth parameters such as petiole width and leaf production were not statistically different between infected and control plants. The incubation period of banana bunchy top disease or appearance of symptoms ranged from 25 to 85 days after aphid inoculation. However, PCR assays provided earlier detection of BBTV in banana plants compared with visual symptoms.

“…It is not uncommon for virus infection to have a negative impact on plant especially by limiting their growth characteristics (Miteva et al, 2005). One explanation for leaf area decrease in inoculated plants could be due to the reduction in the amount of assimilate availability (Ayres, 1992).…”

This study was carried out to determine physiological and biochemical changes in C. moschata inoculated with a Nigerian strain of MWMV isolated from Lagenaria breviflora in Calabar, Nigeria. The virus infection resulted in significant (p#0.05) reductions in plant height, leaf area and number of leaves produces with highest percentage difference of 39.3% (42 PID), 60.9% (35 PID) and 25.7% (49 PID), respectively. There was a significant (p#0.05) difference in chlorophyll content between inoculated and healthy plants. The chlorophyll content of inoculated plants at all stages of growth was lower compared with the healthy plants. Chlorophyll b content was higher than Chl a in both inoculated and healthy plants. Chlorophyll a, b and total Chlorophyll were significantly reduced in inoculated plants when compared with the healthy ones. Of the twelve photochemicals screened, alkaloids, glycosides, saponins, tannins, terpenoids, steroids, polyphenols and reducing sugars were present while phlobatanins, anthraquinones and hydroxymethyl anthraquinones were absent. Moroccan watermelon mosaic virus engendered reductions in alkaloids (32.1%), reducing sugars (42.0%), saponins (33.6%), terpenoids (25.0%) and steroids (15.0%) and increase in inoculated samples of glycosides (14.8%) and flavonoids (12.5%). Effect of MWMV on proximate compositions of C. moschata revealed significant p#0.05) reductions in lipid (25.0%) and ash (14.6%) and significant (p$0.05) increases in protein (23.4%) and fibre (10.5%). Effect of the virus on carotene, vitamin A and C were insignificant. Infection of MWMV also led to significant decreases in the contents of K (48%), Fe (28.6%), Zn (25.0%) and Mg (22.0%), while Cu recorded 100% increase in inoculated samples. Marginal increase in Ca and P were recorded in inoculated samples. Infection of MWMV on antioxidants caused significant increase in inoculated samples of hydrocyanic acid and insignificant increases in total and soluble oxalate and phytic acid. Increases recorded in the antioxidant contents in plants inoculated with MWMV resulted in reduced bioavailability of minerals in the vegetable. Reduction in chlorophyll contents in inoculated plants would be a major factor explaining poor growth of host plants with attendant reductions in mineral elements of C. moschata. Changes in physiological and biochemical parameters induced by MWMV altered vital metabolic processes of C. moschata.

“…Environmental stresses of both biotic and abiotic nature produce characteristic changes in physiology and metabolic processes of higher plants (Miteva et al, 2005). Among these stresses, infection by the pathogens causes substantial alterations of biochemical changes leading to harmful effects on plant health.…”

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.
