| Zusammenfassung: | Copyright © 2018 Elsevier Masson SAS. All rights reserved. The seagrass Zostera marina L. shows optimal growth in marine water and reduced growth under low salinity conditions. However, little is known about the molecular mechanisms underlying its adaptation to high salinity in Z. marina. In this study, transcriptomic analyses were performed using RNA-seq of the following two groups with different NaCl content: the CK group (seagrasses grown in the absence of NaCl) and the NaCl group (seagrasses grown in the presence of 400 mM NaCl for 6 h). Approximately 316 million high-quality reads were generated, and 87.9% of the data were mapped to the reference genome. Moreover, differentially expressed genes between the CK and NaCl groups were identified. According to a functional analysis, the up-regulated genes after the NaCl treatment were significantly enriched in nitrogen metabolism, calcium signalling and DNA replication while the down-regulated genes were significantly enriched in photosynthesis. A comparative transcriptomic analysis detected many differentially expressed genes and pathways required for adaptation to NaCl stress, providing a foundation for future studies investigating the molecular mechanisms of salt adaptation in Z. marina. We discuss how molecular changes in these processes may have contributed to the NaCl adaptation |
