In page Arabidopsis thaliana:

"

Ongoing research on A. thaliana is being performed on the International Space Station by the European Space Agency. The goals are to study the growth and reproduction of plants from seed to seed in microgravity.[1][2]Plant-on-a-chip devices in which A. thaliana tissues can be cultured in semi-in vitro conditions have been described.[3] Use of these devices may aid understanding of pollen-tube guidance and the mechanism of sexual reproduction in A. thaliana.[citation needed]
