Abstract:

Based on transcriptomic data of the desiccation-tolerant moss Syntrichia caninervis under prior 55 ℃ heat stress, this study employed real-time fluorescent quantitative PCR (RT-qPCR) to investigate the expression patterns of nine heat-responsive differentially expressed genes (ScLEA14, ScGSTF11, ScHSP70-17, ScHsfB4b, ScMYB117, ScGLK1, ScERF039, ScERF016, and ScbHLH104) under high temperature, drought-rehydration, and NaCl stress conditions. The aim was to validate the reliability of RNA-Seq data and provide theoretical support for subsequent functional studies on stress-resistant genes in S. caninervis. Results demonstrated that: (1) The expression profiles of all nine genes under high-temperature stress exhibited substantial concordance with RNA-Seq data, confirming the stability of transcriptomic sequencing. (2) Under extreme heat and drought-rehydration stresses, all genes were differentially induced, with three genes attaining peak expression levels following 24-hour drought treatment, while eight genes displayed more prominent transcriptional activation during the rehydration phase. (3) NaCl stress triggered significant upregulation of all nine thermotolerance-associated genes, with six genes demonstrating statistically robust induction. Thus, the results demonstrate that the three genes ScLEA14, ScMYB117, and ScERF016 are strongly induced under extreme high temperature, drought-rehydration, and NaCl-induced high salinity stress, highlighting their potential as key candidate genes for further investigation into stress resistance mechanisms.
