| description | In China, <i>Prunus mume</i> is a famous flowering tree that has been cultivated for 3000 years. <i>P. mume</i> grows in tropical and subtropical regions, and most varieties lack cold resistance; thus, it is necessary to study the low-temperature response mechanism of <i>P. mume</i> to expand the scope of its cultivation. We used the integrated transcriptomic and metabolomic analysis of a cold-resistant variety of <i>P. mume</i> ‘Meiren’, to identify key genes and metabolites associated with low temperatures during flowering. The ‘Meiren’ cultivar responded in a timely manner to temperature by way of a low-temperature signal transduction pathway. After experiencing low temperatures, the petals fade and wilt, resulting in low ornamental value. At the same time, in the cold response pathway, the activities of related transcription factors up- or downregulate genes and metabolites related to low temperature-induced proteins, osmotic regulators, protective enzyme systems, and biosynthesis and metabolism of sugars and acids. Our findings promote research on the adaptation of <i>P. mume</i> to low temperatures during wintering and early flowering for domestication and breeding. |
