This study aimed to explore the formation mechanism of P. qiui leaf and flower color by quantitative evaluation and correlating the factors affecting the coloration of leaves and petals. Leaves from eight developmental stages, and petals from five developmental stages of P. qiui were collected for determination of color parameter, cellular pH, anthocyanin, anthoxanthin, chlorophyll, and carotenoid contents, and it was found that anthocyanins and chlorophylls were closely related to leaf coloration, with anthocyanins being the determinant of leaf red color, while anthocyanidins and anthoxanthins affect the petal coloration, with anthocyanins being more influential. High-performance liquid chromatography (HPLC) analysis showed that leaves contain peonidin-3,5-di-O-glucoside (Pn3G5G), peonidin-3-O-glucoside (Pn3G), and cyanidin-3,5-di-O-glucoside (Cy3G5G), and petals contain Pn3G5G, Pn3G, Cy3G5G, and pelargonidin-3,5-di-O-glucoside (Pg3G5G), with Pn3G5G being the most abundant in both leaves and petals. qRT-PCR analysis revealed that PqDFR, PqANS, and PqMYB113 significantly and positively correlated with anthocyanin accumulation in leaves, and PqF3H promoted anthocyanin accumulation to a greater extent in petals. The findings of this study can provide a theoretical reference for the cultivation of new tree peony varieties and germplasm innovation.","PeriodicalId":15757,"journal":{"name":"Journal of Fruit and Ornamental Plant Research","volume":"5 1","pages":"0-0"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147879474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its prolonged dormancy period or incomplete dormancy release results in low germination rates and extended reproduction cycles, which severely hinders the development of related industries. The <italic>DELAY OF GERMINATION1</italic> (<italic>DOG1</italic>) gene functions as a pivotal factor in seed dormancy regulation. However, it is still unknown how the <italic>DOG1</italic> gene mediates seed dormancy in <italic>P. lactiflora</italic>. In this study, the function and regulatory mechanism of the <italic>PlDOG1</italic> gene were comprehensively analyzed. Through cloning the <italic>PlDOG1</italic> gene and its promoter sequence, it was revealed that the encoded protein possesses a characteristic DOG1 superfamily conserved domain and exhibits high similarity with the <italic>DOG1</italic> gene in other plants, as demonstrated by phylogenetic analysis. Functional studies indicated that <italic>PlDOG1</italic> delays the release of seed dormancy. Moreover, employing Y1H, EMSA, and Dual-LUC assays, we demonstrated that PlARF2 specifically binds to the <italic>PlDOG1</italic> promoter and enhances its transcriptional activity. This creates a new framework for the interaction between the auxin signaling pathway and <italic>DOG1</italic>. The 'PlARF2-<italic>PlDOG1'</italic> regulatory model identified in this study provides a key target for molecular breeding in <italic>P. lactiflora</italic>, offering significant practical value for overcoming technical bottlenecks in <italic>P. lactiflora</italic> seedling cultivation. Additionally, it provides a theoretical basis for understanding the molecular interaction network of auxin and plant hormones in the dormancy regulation of plant seed, significantly advancing seed biology theory and guiding genetic enhancements in horticultural crops.","PeriodicalId":15757,"journal":{"name":"Journal of Fruit and Ornamental Plant Research","volume":"5 1","pages":"0-0"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147886137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have indicated that trehalose and the <italic>trehalose-6-phosphate synthase</italic> (<italic>TPS</italic>) gene family regulate plants' stress resistance, yet their roles in thermotolerance in rose remain uncharacterized. We previously identified <italic>RcTPS7b</italic> as a putative heat-responsive gene in <italic>Rosa chinensis</italic> 'Slater's Crimson China'. This study aimed to investigate whether exogenous trehalose enhances heat tolerance in rose, and elucidate the functional role of <italic>RcTPS7b</italic> in heat stress regulation. The results showed that exogenous application of 5 mmol/L trehalose significantly enhanced rose's heat tolerance by reducing the heat damage index, elevating superoxide dismutase (SOD) activity, and preserving the efficiency of Photosystem II (PSII).

The growth and physiological responses of seedlings under plastic greenhouse cultivation were investigated from June to September. The results showed that the survival rate of seedlings reached 100%, and seedling growth and biomass were the best under SH2, with higher plant height and leaf area than that under other treatments. Water content of seedlings exhibit not difference between three shading levels, and leaves had the highest water content and total soluble sugar content. The chlorophyll content in the leaf increased, but malondialdehyde content decreased with increasing shading layers. Mineral content were in the following order: calcium > potassium > magnesium > sodium, and the translocation factor decreased with increasing shading layers. Antioxidant enzyme activities were in the following order: SOD > PPO > POD > CAT; their activities decreased with increasing shading layers, except for that of PPO. Various correlation existed between physiological response and seedling growth. Shade improved seedling quality through a series of physiological responses under plastic greenhouse conditions.

Variations in the flower color of chrysanthemum are abundant, which is an important feature related to its ornamental and commercial value. However, few reports have elucidated the inheritance of the flower color and pigmentation of chrysanthemum. In this study, an F1 hybrid population, including 319 hybrids of small-flowered chrysanthemum cultivars with different flower color, was constructed. The genetic variation rules for some color and pigment-related traits were discussed based on major gene and polygene mixed inheritance analyses. Both the total anthocyanin and carotenoid contents were controlled by 2 pairs of additive dominant major genes and the heritability of the major genes was 70.44% and 86.03%, respectively. Based on the high-density genetic map constructed for the hybrid population, QTL analysis for the above traits was carried out by using the interval mapping method. A total of 25 related QTLs and 517 closely linked markers were detected, including 3 QTLs controlling the total anthocyanin content and 2 QTLs controlling the total carotenoid content, all of which were major QTLs. Furthermore, 17 unigenes related to pigments were identified via BLAST searches with <italic>Chrysanthemum nankingense</italic> genome. For such genes, the collinearity was observed in four chromosome level genomes, including three genomes of the genus <italic>Chrysanthemum</italic> and the first genome of cultivated chrysanthemum.
