Project description:The pink-flowered strawberry is very popular in China due to its appreciation and economic benefits and its flower has rich red petal with varying degrees, which is provided by anthocyanins accumulation. To better understand the functions of miRNAs, sRNAome, transcriptome and degradome sequencing were used to explore the target genes of miRNAs in flower development and coloring of pink-flowered strawberry. Nine small RNA libraries and a mixed degradome library from flower petals at different developmental stages were constructed and sequenced in this study. A total of 739 known miRNAs and 964 newly identified miRNAs were identified via small RNA sequencing, and their 2816 target genes were cleaved by 639 miRNAs based on the degradome data. There were 317 different expression miRNAs among flower development in pink-flowered strawberry regulated 2134 different expression target genes, which significantly enriched in the transcriptional regulation, phenylpropanoid biosynthesis and plant hormone signal transduction. Furthermore, integrated microRNAomic and transcriptomic analyses suggested that 98 miRNAs were targeted several transcription factors related to anthocyanin accumulation, in which 26 were targeted to MYBs, 12 bHLHs, 14 NACs, and 19 SPLs. And that, twenty seven different expression miRNAs may affect anthocyanin biosynthesis by regulating 23 targets participated in hormone signal transduction pathway in pink-flowered strawberry. The qRT-PCR analysis confirmed the expression changes of 21 miRNA-target pairs showed an opposite trend. Moreover, a co-expression regulatory network was constructed based on differentially expressed miRNA-targets according to the degradome data. Overall, we conducted a comparative analysis uncovered the regulatory functions of microRNAs in flower development and color changes of pink-flowered strawberry via multiple factors, including anthocyanin biosynthesis, hormone signaling and regulation factors. This work not only expands the knowledge of miRNAs affecting the coloration in strawberry, but also provides rich resources for future functional studies.

Project description:The pink salmon (Oncorhynchus gorbuscha) is a commercial anadromous fish species of the family Salmonidae. The species has a peculiar life cycle that includes spawning migration from marine to freshwater environments, which is accompanied by significant adaptive changes in the body, both the physiological and biochemical. This study described and revealed the variability of blood plasma proteomes of female and male pink salmon collected from three different biotopes - marine, estuarine and riverine - that the fish pass through spawning migration. Identification and comparative analysis of pink salmon blood plasma protein profiles were performed using proteomic and bioinformatic approaches. Blood proteomes of female and male spawners collected from different biotopes were qualitatively and quantitatively distinguished. Females differed primarily by proteins associated with reproductive system development (certain vitellogenin and choriogenin), lipid transport (fatty acid binding protein) and energy production (fructose 1,6-bisphosphatase), and males - by proteins involved in blood coagulation (fibrinogen), immune response (lectins) and reproductive processes (vitellogenin). Differentially expressed sex-specific proteins were implicated in proteolysis (aminopeptidases), platelet activation (β- and γ-chain fibrinogen), cell growth and differentiation (a protein containing the TGF_BETA_2 domain) and lipid transport processes (vitellogenin and apolipoprotein). The results obtained are of fundamental and practical importance, providing to the existing knowledge of biochemical adaptations to spawning of pink salmon, representative of the economically important migratory fish species.

Project description:Pink-flowered strawberry is a new promising ornamental flower derived from intergeneric hybridization (Fragaria × Potentilla) with bright color, prolonged flowering period and edible fruits. However, the transcriptional events underlying anthocyanins biosynthesis pathway have not been fully characterized in its petal coloration. The pigment compounds accumulated in its fruits were the same as cultivated strawberry, but different from in its flowers. To gain insights into the regulatory networks related to anthocyanin biosynthesis and identify key genes, we performed an integrated analyses of the transcriptome and metabolomes involved in red petals at three development stages (Bud stage (L), Coloration beginning stage (Z) and Big bud stage (D)) of pink-flowered strawberry. Transcript and metabolite profiles were generated through high-throughput RNA-sequencing and high-performance liquid chromatography coupled with mass spectrometry, respectively. The results showed that the main pigments of red and dark pink petals were anthocyanins, among which cyanidins were the main compounds. There were no anthocyanins detected in white-flowered hybrids. A total of 50 285 non-redundant unigenes were obtained from the transcriptome databases, among which 59 differentially expressed genes could be identified as putative homologues of flower coloration related genes. Based on a comprehensive analysis relating pigmentation compounds to gene expression profiles, the mechanism of flower color formation was examined in pink-flowered strawberry. Furthermore, a new hypothesis explaining the lack of color phenotype of the white-flowered strawberry hybrids from the level of the transcriptome. The expression patterns of FpDFR gene and FpANS gene corresponded to the accumulation patterns of cyanidin contents in pink-flowered strawberry hybrids with different shades of pink; Whereas other anthocyanin biosynthesis genes were weakly related flower color deepened. Moreover, FpANS, FpBZ1 and FpUGT75C1 genes were the key factors that lead to the inability to accumulate anthocyanins in the white petals of PFS hybrids. Meanwhile, the competitive effect of FpFLS gene and FpDFR gene may further inhibit anthocyanin synthesis. The data presented herein are important for understanding of the molecular mechanisms underlying the petal pigmentation and will be powerful for integrating into novel genes that are potential targets for breeding new valuable pink-flowered strawberry cultivars.

Project description:The present work characterizes the response of co-habited Atlantic (Salmo salar), chum (Oncorhynchus keta) and pink salmon (Oncorhynchus gorbuscha) to sea lice infections. Atlantic and pink salmon anterior kidney samples were profiled at three time points over nine days after the start of an experimental infection. Chum salmon anterior kidney was profiled at day six post infection only. All three species were also profiled at six days post exposure for skin responses of the pectoral fin, typically associated with lice infection.
