For Anna-Lisa Paul, taking plants into a space is a way of understanding just what they’re made of. Challenged to survive outside their ancestral environment, plants leverage a unique genetic toolkit to adapt to new challenges; in the process, they reveal how they work. Usinc zero-g experiments, for example, Paul and her colleagues achieved a new understanding of how plants’ roots grow, upending a long-held theory that gravity holds the key. She is currently combining parabolic flight and orbital experiments with imaging and gene expression studies.
