Abstract
Aerial exposure tolerance has been long considered as an important trait for the life survival under acute environmental stress. In this study, we utilized RNA-seq-based transcriptomic profiling to characterize the molecular responses of grand jackknife clam in response to aerial exposure. This assembly yielded 190,856 unigenes with an average length of 1147â¯bp, a minimum length of 201â¯bp, and a maximum length of 51,869â¯bp, with an N50 length of 1875â¯bp. After differential expression analysis, a total of 1344 genes were captured significantly differentially expressed, and were categorized into antioxidant/oxidative stress response, immune alteration, and apoptosis. GO and KEGG analyses revealed that signal transduction, immune response, cellular component organization or biogenesis, and energy production processes were the most highly enriched pathways among the genes that were differentially expressed under aerial exposure stress. All these pathways could be assigned to the following biological functions in the aerial exposure tolerant Solen grandis: signaling, transporter activity, macromolecular complex, cellular component organization or biogenesis, and molecular transducer activity. This study highlighted candidate genes linked to stress response during aerial exposure and provide a useful resource for further work on gills tissue or for selection of aerial exposure tolerant phenotypes.
