Project description:Rubus chingii Hu, indigenous to China, is very rich in flavonoids. With the exception of anthocyanin, fruit flavonoids were much higher than most berries including other raspberry species, which partly contributed to its high phenolics and antioxidant capability. In contrast to other raspberries, anthocyanin and other flavonoids decreased as fruit matured. We investigated four typical phases of fruit maturation using transcriptomics, proteomics and metabolomics. The results indicate that the down-regulation of phenylpropanoid, flavonoid and anthocyanin biosynthesis are responsible for the metabolic decrease. The down-regulation of RcCHS (CL6140.Contig5) and RcCHI (Unigene14858 and Unigene22344) at gene and protein levels were associated with decreases of naringenin/naringenin chalcone respectively. Down-regulation of RcLAR (CL9527.Contig3) at gene and protein levels was consistent with decreases of afzelechin/epiafzelechin, catechin/epicatechin, and gallocatechin/epigallocatechin. However, multiple genes/proteins involved in the enzymatic pathways were divergent and differently regulated, e.g. Rc4CL genes/proteins were down-regulated while Rc4CL-like was maintained at constantly low levels.

Project description:Scurrula chingii (W.C. Cheng) H.S. Kiu is a stem hemiparasite of the genus Scurrula in the family Loranthaceae distributed in southwest China and northern Vietnam. Here, we report and characterize the complete plastid genome sequence of S. chingii to provide genomic resources useful for the phylogenetic studies of Santalales. The plastome of S. chingii is 122,764 bp in length, consisted of a large single-copy region (70,726 bp), a small single-copy region (6,091 bp), and a pair of inverted repeat regions (22,974 bp). The GC content of the whole plastome is 37.2%. It contains 109 genes, including 69 CDS (protein-coding genes), eight rRNAs, and 32 tRNAs. The alignment of 14 species complete chloroplast genomes of Loranthaceae was implemented and a phylogenetic tree was constructed using maximum-likelihood (ML) method, which revealed that S. chingii clustered with Scurrula parasitica and Taxillus thibetensis as a monophyletic group.

Project description:Rubus chingii HU, is a medicinal and nutritious fruit, which is very rich in flavonoids. However, the biosynthesis of its flavonoids is poorly understood. This study examined flavonoids and the genes/proteins at four fruit ripening phases using LC-MS/MS and qPCR. Six major kinds of anthocyanins, primarily consisted of flavanol-anthocyanins, which differed in form or concentration from other Rubus species. In contrast to other known raspberries species, R. chingii had a decline in flavonoids during fruit ripening, which was due to down-regulation of genes and proteins involved in phenylpropanoid and flavonoid biosynthesis. Unexpectedly, anthocyanin also continuously decreased during fruit maturation. This suggests that anthocyanins are not responsible for the fruit's reddish coloration. Flavanol-anthocyanins were derived from the proanthocyanidin pathway, which consumed two flavonoid units both produced through the same upstream pathway. Their presence indicates a reduction in the potential biosynthesis of anthocyanin production. Also, the constantly low expression of RchANS gene resulted in low levels of anthocyanin biosynthesis. The lack of RchF3'5'H gene/protein hindered the production of delphinidin glycosides. Flavonoids primarily comprising of quercetin/kaempferol-glycosides were predominately located at fruit epidermal-hair and placentae. The proportion of receptacle/drupelets changes with the maturity of the fruit and may be related to a decrease in the content of flavonoids per unit mass as the fruit matures. The profile and biosynthesis of R. chingii flavonoids are unique to Rubus. The unique flavonol pathways of R. chingii could be used to broaden the genetic diversity of raspberry cultivars and to improve their fruit quality.
