Abstract

Plants are an important component of the controlled ecological life-support system (CELSS) for future long-term spaceflight and the International Space Station. Therefore, it is critical to understand the susceptibility of plants to pathogen infection in microgravity. An increase in both hyphal growth and sporangia formation in Phycomyces blakes in microgravity has been described. Plant cell walls, a critical barrier for pathogen invasion, have been reported to undergo changes in microgravity including changes in the wall structure. For example, a decrease in the crystalline cellulose content and an increase in the hemicellulose content in cell walls of plants grown in clinostats and in microgravity have been reported. Based of these previous reports, we hypothesize that susceptibility of plants to pathogen infection in microgravity would be increased relative to the ground control.
