Proline plays a crucial role in plant growth, development, and defense against various biotic and abiotic stresses. This study investigates the expression of proline transporter (ProT) genes in tomato (Solanum lycopersicum) under cold stress. Using Istek F1 seedlings, plants were exposed to cold treatment at +4°C for 24 hours, and RNA was extracted from leaf and root tissues. Gene expression analysis via RT-qPCR revealed tissue-specific responses, with most SlProT genes being downregulated in the leaves, except for SlProT2, which showed a 2.38-fold increase, suggesting its vital role in cold tolerance. In contrast, SlProT3 was significantly repressed in both tissues, especially in roots, where its expression dropped by 2.88-fold. The findings highlight the differential regulation of SlProT genes under cold stress and provide insights into the role of proline transporters in enhancing plant resilience against environmental stresses. These results offer a foundation for further studies on improving crop tolerance to abiotic stresses through the manipulation of proline transport pathways.
