According to the paper, microgravity can cause too much or too little water in root zones, and the effects of this problem can be seen in transcriptomic studies
where gene expression in space plants indicates possible hypoxic stress. The author's reference Bakshi et al. (2023) in relation to the possibility of engineering
focused on CAX2 leading to flood-resistant plants.

transporter CATION EXCHANGER 2 regulates cytosolic calcium homeostasis, hypoxic signaling, and response to flooding in Arabidopsis thaliana. New Phytologist,
240(5), 1830-1847.
Bakshi et al. found that cax2 mutants (knockout) had greater base levels of Ca2+ in the cytosol and a greater induction of the Ca2+
signal, which led to a greater response to hypoxic stress from flooding of the root zone. These plants exhibited less reduction in growth and a greater adaptation
to flooding than did wild-type plants.
