Gypsophytes and the use of Martian Gypsum: A review of their potential for agriculture on Mars
Gypsophytes are plants that thrive on gypsum soils on Earth. They possess some adaptive traits that could constitute pre-adaptations to the conditions for potential cultivation in a controlled habitat on Mars.

| Sumario: | Gypsophytes are plants that thrive on gypsum soils on Earth. They possess some adaptive traits that could constitute pre-adaptations to the conditions for potential cultivation in a controlled habitat on Mars. Martian agriculture should utilize substrates obtained directly from the planet itself. However, the detection of perchlorates in the soil of Mars raises doubts about this possibility. These molecules are distributed globally and in concentrations toxic to both humans and plants. The polar winds may preserve some Martian gypsum outcrops from the effects of perchlorates. If so, using this Martian gypsum as a growing substrate for gypsophytes may be a viable option. In the medium term, implementing gypsophyte adaptations on staple crops would also be possible using CRISPR-Cas9 and/or other gene-editing technologies. According to the literature reviewed, Gypsophila struthium subsp. struthium shows a high degree of colonization capacity and high resistance to drought. This taxon serves as an ecological facilitator for other species, and its germination appears to be favored by the presence of gypsum. Several experimental results suggest it would be worthwhile to test the cultivation of this and other plants on reliable simulants or Martian gypsum through sample return missions or on a mission that would perform the cultivation on Mars itself. |
