Nanotitania Exposure Causes Alterations in Physiological, Nutritional and Stress Responses in Tomato (Solanum lycopersicum).

ABSTRACT: Titanium dioxide nanoparticles (nanotitania: TiO₂NPs) are used in a wide range of consumer products, paints, sunscreens, and cosmetics. The increased applications lead to the subsequent release of nanomaterials in environment that could affect the plant productivity. However, few studies have been performed to determine the overall effects of TiO₂NPs on edible crops. We treated tomato plants with 0.5, 1, 2, and 4 g/L TiO₂NPs in a hydroponic system for 2 weeks and examined physiological, biochemical, and molecular changes. The dual response was observed on growth and photosynthetic ability of plants depending on TiO₂NPs concentrations. Low concentrations (0.5-2 g/L) of TiO₂NPs boosted growth by approximately 50% and caused significant i
