Papaver somniferum L. (poppy) is a pharmaceutically important plant valued for its alkaloids (morphine, codeine, narcotine, laudanosine, papaverine, oripavine) that relieve pain, reduce spasms, ease agitation, induce sleep, and lessen anxiety. As global temperatures continue to rise, plants are encountering growing difficulties in their growth, development, and metabolic balance. Over time, plants have evolved systems to tolerate heat. Information on the function of genes underlying the response to high temperature is critical for developing adaptation strategies and for identifying or developing cultivars with phenotypic plasticity. However, the genes and molecular pathways associated with elevated temperature responses in poppy remain largely unexplored, and no transcriptomic study has characterized the temperature-dependent regulation in poppy at different temperature gradients. In this study, transcriptomic profiling of seedling-stage poppy cultivar ‘Çelikoğlu’ exposed to three temperatures (21, 26, and 30°C) was conducted. Compared to control (21°C), 8524 differentially expressed genes (DEGs) were identified at 26°C, 9852 at 30°C, and 1441 between 26 and 30°C. Gene ontology and KEGG analyses revealed enrichment in pathways including photosynthesis, RNA modification, amino acid and carbohydrate biosynthesis, and chaperone transport. The genes related to abiotic stress, cell wall formation, and cytokinin signaling represent potential genes involved in temperature-responsive regulatory processes. The occurrence of temperature-sensitive changes in the expression of genes within benzylisoquinoline alkaloid (BIA) biosynthetic pathways indicates a potential regulatory role for temperature at the transcriptomic level in secondary metabolism. Our findings highlight candidate genes that may contribute to stress tolerance and will guide future breeding efforts aimed at enhancing poppy’s thermal resistance.
