Cell wall modifications and gravitational adaptation shape plant spaceflight responses

This reasoning chain connects mechanistic insights from terrestrial studies on plant cell wall composition, gravity resistance, and gravitropism to the observed changes in Arabidopsis root cell walls under spaceflight. It links established roles of the cell wall in gravity sensing, evolutionary adaptation for terrestrialization, and known genetic and developmental mediators to the epitope and secondary wall changes reported in space-exposed roots.
