Mango wilt is one of the most important diseases affecting mango production, yet the physiological mechanisms underlying host responses to this fungal infection are poorly known. The disease attenuation displayed by some mango cultivars might be related to higher antioxidant capacities in leaves. To test this hypothesis, the activities of a range of
enzymes (e.g. superoxide dismutase and catalase) and metabolites (e.g. ascorbate and glutathione) involved in the antioxidant system, as well as some markers for oxidative stress (e.g. hydrogen peroxide and malondialdehyde equivalents), were evaluated for 30 days after the inoculation of mango plants withCeratocystis fimbriata. Tommy Atkins plants
displayed higher values for the upward, downward and radial fungal colonization of the stem tissues than Uba plants.
In contrast to the working hypothesis, Tommy Atkins plants exhibited more prominent increases in enzyme activities
and metabolite concentrations related to oxidative stress responses. These increases were minimal, if any, in Uba
plants. These results suggest that Tommy Atkins plants are less effective at restraining fungal spread through vascular
tissues and thus trigger leaf antioxidant defences to cope with the developing stress. |
