Resumo

How the diversity of alternatively spliced isoforms contribute to adaptation to extreme environments is a fundamental topic in evolutionary biology. Located on the shores of Lake Tuz, Turkey, where soils accumulate high concentrations of multi-ion salts, Schrenkiella parvula is a robust salt-tolerant extremophyte model for investigating multiple abiotic stresses. In recent years, fundamental genomic resources have been created for S. parvula. However, transcript diversity enabled by alternatively spliced isoforms and their spatiotemporal presence and interactions are poorly explored. We investigated the potential molecular mechanisms and expression patterns at the isoform level associated with multiple salt stresses in S. parvula. Using full-length reference transcripts generated by Iso-Seq and a spatiotemporal expression profile generated from 107 RNA-Seq samples including different tissues and developmental stages, we quantified the expression of > 70,000 isoforms and identified those that respond to tissue-specific saline stress. Differentially expressed isoforms were enriched in functional categories related to metabolic, biosynthetic and homeostasis processes, transport, protein folding and stress response. We built a global co-expression network to deduce the main metabolic pathways and isoform-specific tissue responses that may govern salinity tolerance throughout the lifecycle of this extremophyte. Insight gained from this work will advance our knowledge about the adaptive evolution of extremophytes, especially in the face of climate change.
