|a Pinellia ternata, a valuable Chinese herb, suffers yield reduction due to "sprout tumble" under high temperatures. However, the mechanisms underlying its high-temperature stress remain poorly understood. NAM, ATAF1/2, and CUC2 (NAC) transcription factors regulate plant tissue growth and abiotic stress. Hence, there has been no comprehensive research conducted on NAC transcription factors in P. ternata. We identified 98 PtNAC genes unevenly distributed across 13 chromosomes, grouped into 15 families via phylogenetic analysis. Gene expression analysis revealed diverse expression patterns of PtNAC genes in different tissue types. Further studies revealed that PtNAC5/7/17/35/43/47/57/66/86 genes were highly expressed in various tissues of P. ternata and induced by heat stress, among which PtNAC66 was up-regulated at the highest folds induced by heat temperature. PtNAC66 is a nuclear protein that can selectively bind to the cis-responsive region NACRS but lacks the ability to activate transcription in yeast. For further research, PtNAC66 was cloned and transgenic Arabidopsis was obtained. PtNAC66 overexpression increased high-temperature tolerance compared to wild-type plants. Transcriptome profiling demonstrated that overexpression of PtNAC66 led to significant modification of genes responsible for regulating binding, catalytic activity, transcription regulator activity and transporter activity response genes. Additionally, PtNAC66 was found to bind the promoters of CYP707A3, MYB102 and NAC055, respectively, and inhibited their expression, affecting the high-temperature stress response in Arabidopsis. Our research established the foundation for functional studies of PtNAC genes in response to high-temperature forcing by characterizing the P. ternata NAC gene family and examining the biological role of PtNAC66 in plant high-temperature tolerance
