Increasing exposure to unfavorable temperatures and water deficit imposes major constraints on most crops worldwide. Despite several studies regarding coffee responses abiotic stresses, transcriptome modulation due simultaneous stresses remains poorly understood. This study unravels transcriptomic under the combined action of drought temperature in leaves from two traded species: Coffea canephora cv. Conilon Clone 153 (CL153) C. arabica Icatu. Substantial changes were found, especially response combination that cannot be explained by an additive effect. A large number genes involved stress responses, with photosynthesis other physiologically related usually being negatively affected. In both genotypes, encoding for protective proteins, such as dehydrins heat shock positively regulated. Transcription factors (TFs), including MADS-box genes, down-regulated, although genotype-dependent. contrast Icatu, only a few drought- heat-responsive DEGs recorded CL153, which also reacted more significantly terms enriched GO terms, suggesting high ability cope stresses. research provides novel insights into molecular mechanisms underlying leaf heat, revealing their influence gene expression.
