Effects of Space low dose radiations on metabolome of ediable plants
Abstract
Growing edible plants in future space missions will be fundamental for providing fresh and appropriate dietary intake for astronauts and allowing a sustainable food supply that represents a substantial cargo problem on space missions. Exposure to ionizing radiations may affect space travelers but also other living organism on these missions such as plants. Since plants are sessile organisms, they have developed highly efficient protective strategies to avoid the harmful effects of the ultraviolet radiations, however, they have always evolved under the protective atmosphere and cosmic radiation may affect their growth, reproduction, primary and secondary metabolism. The production of secondary metabolites may be protective, neutral or toxic for human consumption. Our study focuses on the quantification of secondary metabolites of edible plants that have been grown on our dispositive (Marsimulator) providing chronic low dose radiation simulating a travelling to Mars (600-800μm/day) without solar radiation incident.
