Tree peony (Paeonia suffruticosa Andr.) is a traditional Chinese flower, which prefers cool weather. However, high temperature in summer in the middle and lower reaches of the Yangtze River restricts its growth and development. In this study, osmotic regulation, antioxidant enzyme activities, and photosynthetic characteristics of tree peony in response to high-temperature stress were investigated. The results showed that high-temperature stress had destroyed the cell membrane, manifested as the increased relative electrical conductivity and malondialdehyde content. Moreover, high-temperature stress led to excessive accumulation of reactive oxygen species, thereby, activating antioxidant enzyme activities. Also, photosynthetic parameters and chlorophyll fluorescence parameters directly reflected the damage to the photosystem II reflection center under high-temperature stress. In addition, high-temperature stress led to stomatal closure and chloroplast damage. This study revealed the physiological responses of tree peony to high-temperature stress, laying a foundation for the promotion of tree peony in high-temperature areas and the improvement of high-temperature resistance.

“…The photosynthesis of plants is mainly measured by the values of Pn, Ci, Gs, and Tr. Studies show that the photosynthesis of plants will change with the degree and time of stress [21,29,30]. The Pn, Ci, Gs, and Tr of tree peony were significantly decreased under HT-treated.…”

“…In field conditions, the primary constraint on bud burst and flowering lies in the release of bud endodormancy. Artificial chilling and the application of phytohormones, such as gibberellins (GAs), garlic paste, 5-azacytidine (5-azaC), and ABA, were considered as effective strategies [15][16][17]. Additionally, several crucial factors, including TARGET OF EAT (PsTOE3), β-1,3-glucanase gene PsBG6, PsMYB1, and others, have been confirmed to be involved in the dormancy release process [15,18].…”

Tree peony (Paeonia suffruticosa Andr.) is a traditional Chinese flower with significant ornamental and medicinal value. Its growth and development process is regulated by some internal and external factors, and the related regulatory mechanism is largely unknown. Myelocytomatosis transcription factors (MYCs) play significant roles in various processes such as plant growth and development, the phytohormone response, and the stress response. As the identification and understanding of the MYC family in tree peony remains limited, this study aimed to address this gap by identifying a total of 15 PsMYCs in tree peony and categorizing them into six subgroups based on bioinformatics methods. Furthermore, the gene structure, conservative domains, cis-elements, and expression patterns of the PsMYCs were thoroughly analyzed to provide a comprehensive overview of their characteristics. An analysis in terms of gene structure and conserved motif composition suggested that each subtribe had similarities in function. An analysis of the promoter sequence revealed the presence of numerous cis-elements associated with plant growth and development, the hormone response, and the stress response. qRT-PCR results and the protein interaction network further demonstrated the potential functions of PsMYCs in the growth and development process. While in comparison to the control, only PsMYC2 exhibited a statistically significant variation in expression levels in response to exogenous hormone treatments and abiotic stress. A promoter activity analysis of PsMYC2 revealed its sensitivity to Flu and high temperatures, but exhibited no discernible difference under exogenous GA treatment. These findings help establish a basis for comprehending the molecular mechanism by which PsMYCs regulate the growth and development of tree peony.
