Multi-omics contribute to fragrance formation mechanism analysisįragrance is one of the most distinctive ornamental characteristics of ornamental plants. Moreover, ChlH and POLGAMMA2 changed chlorophyll synthesis and chloroplast ultrastructure by working with several structural genes, which were confirmed by virus-induced gene silencing and transient overexpression analyses. Numerous candidate DEGs (especially ChlH and POLGAMMA2) were screened out by comparative transcriptome. measured pigment content and observed leaf anatomical structure of yellow-leaf and green-leaf progenies derived from a hybrid population, and found that yellow-leaf individuals were deficient in chlorophyll and the chloroplast structure. To shed light on the regulatory mechanisms of the yellow-leafed Forsythia, Zhang et al. Moreover, yeast one-hybrid (Y1H) and dual‐luciferase reporter assays (DLR) showed that DhMYB2 and DhbHLH1 combined with the promoter regions of five structural genes ( DhF3’H1, DhF3’5’H2, DhDFR, DhANS, and DhGT4) to activate their transcription. Furthermore, 29 DEGs involved in anthocyanin biosynthesis were screened by transcriptome and their expression patterns are similar to those of DhMYB2 and DhbHLH1. found that DhMYB2 and DhbHLH1, related to anthocyanin biosynthesis, are highly expressed in purple floral tissues. Their study provided a novel insight into flower coloration mechanism in Rosa. Thirty-five differentially expressed genes (DEGs) play a role in the upstream pathway of anthocyanin biosynthesis, regulating the total amount of C圓G5G and Pn3G5G, and RrAOMT regulates the ratio of C圓G5G and Pn3G5G through methylation and determines the color of the petals. explored the mechanism of flower color formation in Rosa rugosa through a combination of chemical and transcriptome analysis. Multi-omics contribute to color formation mechanism analysisĬyanidin 3,5-O-diglucoside (C圓G5G) and peonidin 3,5-O-diglucoside (Pn3G5G) were the primary anthocyanins in rose petals, whose total content and proportion play a role in the depth and hue of the petals, respectively. simsii mitochondrial genomes, which is useful for the study of population genetics and evolution in Rhododendron and other genera in Ericaceae. The results of genome collinear alignment and phylogenetic tree analyses verified that there was gene rearrangement between R. 88 simple sequence repeats (SSR) and five genes ( nad1, nad2, nad4, nad7, and rps3) were identified and developed as a molecular marker. assembled a mitochondrial genome of Rhododendron × pulchrum with a length of 816,410 bp and 64 mitochondrial genes. With the help of multi-omics, numerous transcription factors (TFs) and candidate genes associated with heat stress response and aroma compounds were identified based on the genome, transcriptome and metabolome integration analysis, which lays the foundation for genetic improvement of jasmine flowers.Īnother well-known ornamental plant, Rhododendron, is used extensively in gardens. sambac, and its divergence from Osmanthus fragrans and Olea europaea occurred approximately 31.1 million years ago. Only an ancient whole-genome duplication event was occurred in J. sambac cultivar ‘Danbanmoli’ was assembled by Qi et al., with a size of 520.80Mb and 353,363 predicted genes.
Jasmine is famous for its strong fragrance and is used as raw material for scented tea and essence. Genome sequencing is an important step toward correlating genotypes with phenotypic characters. To explore this interesting research direction, this editorial showcases recent findings and novel insights into “Application of Multi-Omics” to broaden our current understanding of genetic mechanisms responsible for important agronomic, ornamental and resistance traits in ornamental plants and beverage crops. However, the study of single omics has great limitations, and there is an urgent need to apply multi-omics to the study of ornamental plants and beverage plants. With the rapid development of sequencing technology, omics research has been applied to ornamental plants and beverage plants, resulting in a large amount of omics data, such as genome, transcriptome, proteome, metabolome, etc. Ornamental plants contribute to the beautification of the environment, and beverage plants are the raw materials for people’s favorite beverages, both of which play an indispensable role in human production and life.
