Gap in direct plant growth data for Martian regolith

Synthesizes citations on Martian soil mineralogy and reconstructions of past aqueous environments, identifying the key gap that few direct plant growth experiments using actual or simulated Martian regolith have been performed. Papers by Schuerger et al., Bibring et al., Gendrin et al., Arvidson et al., and Christensen et al. inform this inference.
