Targeted metabolite and molecular profiling of carotenoids in rose petals: A step forward towards functional food applications.

Given the increasing consumer demand for natural and functional foods, rose petals offer a promising novel ingredient for food innovation, especially yellow and orange rose petals rich in carotenoids, making them ideal for food processing and color retention. Despite their potential, the metabolic profile of carotenoids in roses has not yet been fully explored. Therefore, the present study aimed to provide a comprehensive analysis of carotenoid metabolism in rose petals during three developmental stages.

Multi-omics analyzes of Rosa gigantea illuminate tea scent biosynthesis and release mechanisms.

Rose is an important ornamental crop cultivated globally for perfume production. However, our understanding of the mechanisms underlying scent production and molecular breeding for fragrance is hindered by the lack of a reference genome for tea roses. We present the first complete telomere-to-telomere (T2T) genome of Rosa gigantea, with high quality (QV > 60), including detailed characterization of the structural features of repetitive regions.

Identification and QTL Analysis of Flavonoids and Carotenoids in Tetraploid Roses Based on an Ultra-High-Density Genetic Map.

Roses are highly valuable within the flower industry. The metabolites of anthocyanins, flavonols, and carotenoids in rose petals are not only responsible for the various visible petal colors but also important bioactive compounds that are important for human health. In this study, we performed a QTL analysis on pigment contents to locate major loci that determine the flower color traits.
