|a Mesoporous silica nanoparticles (MSNs) of 50 nm diameter particle size with a pore size of approximately 14.7 nm were functionalized with amino groups (Am-MSNs) and the effects of exposure to these positively charged Am-MSNs on each of the life cycle stages of Arabidopsis thaliana were investigated. After growth in half strength MS medium amended with Am-MSNs (0-100 μg/mL) for 7 and 14 days, seed germination rate and seedling growth were significantly increased compared with untreated controls. The seedlings were then transferred to soil and irrigated with Am-MSNs solutions every 3 days until seed harvesting. After four weeks growth in soil, Am-MSNs treated plants showed up-regulation of chlorophyll and carotenoid synthesis-related genes, an increase in the content of photosynthetic pigments and an amplification of plant photosynthetic capacity. All these changes in plants were closely correlated with greater vegetative growth and higher seed yield. In all the experiments, 20 and 50 μg/mL of Am-MSNs were found to be more effective with respect to other treatments, while Am-MSNs at the highest level of 100 μg/mL did not result in oxidative stress or cell membrane damage in the exposed plants. To the best of our knowledge, this is the first report evaluating both physiological and molecular responses following exposure to plants of these specific Am-MSNs throughout their whole life cycle. Overall, these findings indicate that following exposure Am-MSNs play a major role in the increase in seed germination, biomass, photosynthetic pigments, photosynthetic capacity and seed yield in A. thaliana
