An on-line high-performance liquid chromatography-diode-array-detector-electrospray ionization-ion-trap-time-of-flight-mass spectrometry-total antioxidant capacity detection (HPLC-DAD-ESI-IT-TOF-MS-TACD) system was applied for the identification and evaluation of antioxidants in Rosa chinensis Jacq., an edible flower in food industry and a widely used traditional Chinese medicine. With the help of this platform, the HPLC fingerprint, mass fragmentations, and sample activity profiles against 1,1-diphenylpicryl-2-hydrazyl radical (DPPH•) and ferric reducing antioxidant power (FRAP) were recorded after one injection. Using this technique, 80 compounds were separated and identified by their LC/MS behaviors with the assistance of standard compounds. In addition, 11 different Rosa chinensis Jacq. samples were profiled and then quantified for their DPPH• and FRAP activities. Interestingly, a total of 52 compounds showed antioxidative effects against DPPH• and 61 were active against FRAP. The results demonstrated that the on-line system is a powerful technique for antioxidant discovery in Rosa chinensis Jacq. and other food resources.

Roses () are among the most cherished ornamental plants globally, yet they are highly susceptible to infections by , the causative agent of gray mold disease. Here we inoculated the resistant rose variety 'Yellow Leisure Liness' with to investigate its resistance mechanisms against gray mold disease. Through transcriptome sequencing, we identified 578 differentially expressed genes (DEGs) that were significantly upregulated at 24, 48, and 72 hours post-inoculation, with these genes significantly enriched for three defense response-related GO terms.

In recent years, the global rise in temperatures has led to drought and heat becoming major environmental stresses that limit plant growth. Previous research has demonstrated the potential of in augmenting plant stress resistance. However, specific studies on its effects and underlying mechanisms in cuttings of , and Planch are relatively limited.

In this study, smart films of EFS, EFS-SiO and EFS-SiO-CRE were successfully developed by using Euryale ferox starch (EFS), nano-SiO and Chinese rose extract (CRE). The Chinese rose flower had a high content of anthocyanins (1.73 mg/g) and CRE exhibited different colors in varying pH buffers (2-13).

Article Synopsis
- * A total of 100 MYB-related proteins were identified, primarily localized in the nucleus, and mapped across seven chromosomes, with evidence of collinear gene relationships indicating potential evolutionary duplication events.
- * The study found that Motif 3 is the most conserved across MYB-related genes, and specific treatments with ABA and MeJA can influence gene expression, particularly in petals, indicating a significant role for these factors in flower senescence and growth regulation.

This study explores the impact of natural flower extracts from , , and to enhance the aroma of dealcoholized Chardonnay wine, addressing the sensory deficiencies commonly associated with dealcoholized wine beverages (DWBs). The investigation revealed a richer bouquet of aromatic compounds, particularly higher alcohols, esters, and terpenes, which significantly elevated the aromatic profile of treated wines without altering their physicochemical properties. Principal Component Analysis (PCA) showed distinct aroma profiles between control and flower extract-DWBs, with the latter exhibiting enhanced floral and fruity characteristics.
