| Summary: | Calcite processed particles (CaPPs, Megagreen<sup>®</sup>) elaborated from sedimentary limestone rock, and finned by tribomecanic process were found to increase photosynthetic CO<sub>2</sub> fixation grapevines and stimulate growth of various cultured plants. Due to their processing, the CaPPs present a jagged shape with some invaginations below the micrometer size. We hypothesised that CaPPs could have a nanoparticle (NP)-like effects on plants. Our data show that CaPPs spontaneously induced reactive oxygen species (ROS) in liquid medium. These ROS could in turn induce well-known cellular events such as increase in cytosolic Ca<sup>2+</sup>, biotic ROS generation and activation of anion channels indicating that these CaPPs could activate various signalling pathways in a NP-like manner. |
