Cover Story: The Advanced Plant Habitat experiment 2 grew radish plants on the International Space Station (ISS) twice for 27 days each. Leaf punch (LP) samples and bulb tissue samples were compared with ground controls (GC) from the Kennedy Space Center (KSC) and lab plants. Genes characterizing general metabolism and stress responses were measured using qPCR and compared with RNA-seq and displayed stable transcription in LP samples in GC but decreased in ISS samples. RNA-seq resulted in different profiles than LP data, and RNA-seq of leaf samples displayed greater variety than qPCR data. Time analyses showed small changes in space and ground controls. This is the first study comparing developmental changes in space-grown plants with ground controls based on a comparison of RNA-seq and qPCR.
