UNLABELLED: Chilling Tolerant Divergence 1 (COLD1) gene consists of Golgi pH Receptor (GPHR) as well as Abscisic Acid-linked G Protein-Coupled Receptor (ABA_GPCR), which are the major transmembrane proteins in plants. This gene expression has been found to be differentially regulated, under various stress conditions, in wild Saccharum-related genera, Erianthus arundinaceus, compared to commercial sugarcane variety. In this study, Rapid Amplification of Genomic Ends (RAGE) technique was employed to isolate the 5' upstream region of COLD1 gene to gain knowledge about the underlying stress regulatory mechanism. The current study established the cis-acting elements, main promoter regions, and Transcriptional Start Site (TSS) present within the isolated 5' upstream region (Cold1P) of COLD1, with the help of specific bioinformatics techniques. Phylogenetic analysis results revealed that the isolated Cold1P promoter is closely related to the species, Sorghum bicolor. Cold1P promoter-GUS gene construct was generated in pCAMBIA 1305.1 vector that displayed a constitutive expression of the GUS reporter gene in both monocot as well as dicot plants. The histochemical GUS assay outcomes confirmed that Cold1P can drive expression in both monocot as well as dicot plants. Cold1P's activities under several abiotic stresses such as cold, heat, salt, and drought, revealed its differential expression profile in commercial sugarcane variety. The highest activity of the GUS gene was found after 24 h of cold stress, driven by the isolated Cold1P promoter. The outcomes from GUS fluorimetric assay correlated with that of the GUS expression findings. This is the first report on Cold1P isolated from the species, E. arundinaceus.SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s13205-023-03650-8.
