Gluconacetobacter diazotrophicus is a diazotrophic endophyte that is a potential biofertilizer. Little is known about the mechanisms of G. diazotrophicus interaction with its host plants. We tested the effect of UV light, as an inducer of secondary metabolite accumulation, on the association between common bean ( Phaseolus vulgaris L.) seedling roots and G. diazotrophicus. UV light irradiation of seedlings 4 h prior to bacterial inoculation increased the number of bacterial cells associated with the roots by 5.65-fold with respect to a nonirradiated control (p < 0.05). Gluconacetobacter diazotrophicus associates with root hairs and root border cells. Aggregation of bacterial cells was observed in root structures from UV-induced seedlings. Secondary metabolite accumulation was also observed in roots from UV-irradiated seedlings.

Powdery Mildew Infection

The effect of silicon (Si) foliar applications on metabolic changes and powdery mildew infection in strawberry plants were determined. Silicon was used in the forms of potassium (K) and sodium (Na) salts. Foliar sprays containing 0, 250, 500, 750, and 1000 ppm of Si were applied. Strawberry plants showed no difference in response to the K or Na salts of Si during the seven weeks of experimental period. Plants treated with potassium and sodium silicate showed reduced severity of powdery mildew, increased chlorophyll content, and increased plant growth. Potassium and sodium silicate treatments also induced metabolic changes such as an increase in citric acid and malic acid levels, and a decrease in fructose, glucose, sucrose, and myoinositol content. The treated tissues also had higher ratios of (18:2 + 18:3)/18:1 in glycolipids and phospholipids and elevated amounts of membrane lipids in leaves and petioles. These results suggest that Si has beneficial effects on strawberry plants and may serve as an alternative to fungicides for controlling powdery mildew.
