Title

Toxicity of Copper oxide nanoparticle on physiology and biochemistry of Solanum lycopersicum as evident by growth, photosynthetic pigment content and PS II photochemistry: toxicity alleviation by calcium

Abstract

Copper oxide nanoparticles (CuONPs) toxicity has greatly affected the environment and particularly plants , It cause rapid changes in plant morphology and physiology however the changes can be restored via exogenous supplementation of Calcium (Ca). Thus, the present work has been undertaken to elucidate the impacts of Ca supplementation on lessing the CuONPs toxicity in S. lycopersicum. The CuONPs at both the doses (500 and 1000 µM) showed significant reduction in growth, protein content, photosynthetic pigments, PS II photochemistry, contrastingly the reactive oxygen species (SOR and H2O2) were significantly raised as confirmed by in- vitro and in-vivo visualization of SOR and H2O2 that eventually leads to cell death. Now a days the nutrient management technique is widely been used for the release of plants from the toxic effect caused by the pollutants. In this study the toxicity alleviation is achieved by exogenous application of calcium (Ca). The Ca is a macronutrient that act as an signalling molecule and produces a remarkable enhancement in growth attributes, protein content, photochemistry of PS II. Besides physiological respnses Ca also reduced the ROS generation. So, the study concluded that, Ca not only shields growth and development of plants from CuONPs toxicity but also reduce the generation of ROS.

Key Words
