Study examining low-speed clinorotation of brachypodium distachyon and arabidopsis thaliana. Microgravity profoundly affects plant biology, disrupting normal gravitropic responses while enhancing phototropism. Gene expression, cell wall structure, and reproductive processes are all modified. Understanding these adaptations is crucial for developing sustainable food production systems for long-duration space missions.
Study examining low-speed clinorotation of brachypodium distachyon and arabidopsis thaliana. Plant growth and development were significantly altered in microgravity conditions. Root gravitropism was disrupted with random directional growth. Phototropic responses remained functional but were enhanced. Gene expression patterns differed substantially from ground controls. Cell wall synthesis and structure were modified. Flowering time and reproductive success varied among species tested.
