Eruca sativa Rocket Science RNA-seq

Metadata Updated: December 7, 2023

In the Rocket Science citizen science project Eruca sativa (salad rocket) seeds stored for six months on board of the International Space Station caused delayed crop establishment. Here we investigated the physiological and molecular mechanisms underpinning the spaceflight effects on dry seeds. We found that Space seed germination vigor was reduced and aging sensitivity increased but the spaceflight did not compromise seed viability and the development of normal seedlings. Comparative analysis of the transcriptomes (using RNASeq) in dry seeds and upon controlled artificial aging treatment (CAAT) revealed differentially expressed genes (DEGs) associated with spaceflight and ageing. DEG categories enriched by spaceflight and CAAT included transcription and translation with reduced transcript abundances for 40S and 60S ribosomal subunit genes. Among the spaceflight-up DEGs were Heat Shock Protein (HSP) DNAJ-related chaperones a Heat Shock Factor (HSFA7a-like) and components of several DNA repair pathways (e.g. ATM DNA ligase1). The response to radiation category was especially enriched in spaceflight-up DEGs including HSPs catalases and the transcription factor HY5. The major finding from the physiological and transcriptome analysis is that spaceflight causes vigor loss and partial ageing during air-dry seed storage for which space environmental factors and consequences for seed storage during spaceflights are discussed.
