Abstract

Tomato (Solanum lycopersicum L.) is a crucial vegetable crop worldwide, facing significant challenges due to climate change-induced heat stress. Elevated temperatures negatively impact tomato productivity by disrupting various physiological and reproductive processes. To mitigate these challenges, there is increasing interest in harnessing genetic resources from crop wild relatives (CWRs) through introgression breeding. This review explores recent advancements in understanding heat stress tolerance mechanisms in tomatoes and the prospects of introgressing heat tolerance genes from CWRs into cultivated tomato varieties. The complex responses of tomato plants to heat stress, focusing on reproductive traits, pollen viability, and physiological and biochemical adaptations are discussed. Additionally, highlight the genetic basis of heat tolerance and the role of various genes, QTLs, and enzymes in mediating heat stress responses. Furthermore, review emerging biotechnological approaches, including transcriptomics, proteomics, genome-wide association studies (GWAS), metabolomics, and advanced imaging techniques, for enhancing heat stress tolerance in tomatoes. Finally, we address the challenges and opportunities in introgression breeding and emphasize the importance of utilizing CWRs as valuable genetic resources for developing heat-tolerant tomato varieties
