New insights into genome assembly at the chromosome‐level of Prunus tomentosa in evolution and cold tolerance

Year: 2025
Type: article
Abstract: This study assembled a high-quality chromosome-level genome of Prunus tomentosa, offering a vital resource for elucidating its genetic architecture, evolutionary relationships, and facilitating genome-assisted breeding efforts. Multi-omics integration revealed PtIMP3 and PtMIOX1L as key factors in cold tolerance of P. tomentosa. PtIMP3 drives the conversion of glucose-6-phosphate to myo-inositol, while PtMIOX1L catalyzes myo-inositol to d-glucuronic acid. Specifically, the high expression abundance of PtIMP3 and low expression abundance of PtMIOX1L resulted in high endogenous inositol levels in P. tomentosa. The application of myo-inositol enhanced the cold tolerance of cherry rootstocks by modulating reactive oxygen species concentrations and maintaining a stable relative water content. This finding supports the superior performance of P. tomentosa in adapting to extreme low-temperatures environmental conditions. These insights advance strategies for improving cold tolerance in horticultural crops, bridging fundamental research with practical applications in developing climate-resilient crops.
