Project description:Fragaria vesca, a diploid woodland strawberry with a small and sequenced genome, is an excellent model for studying fruit development. The strawberry fruit is unique in that the edible flesh is actually enlarged receptacle tissue. The true fruit are the numerous dry achenes dotting the receptacleM-^Rs surface. Auxin produced from the achene is essential for the receptacle fruit set, a paradigm for studying crosstalk between hormone signaling and development. To investigate the molecular mechanism underlying strawberry fruit set, next-generation sequencing was employed to profile early-stage fruit development with five fruit tissue types and five developmental stages from floral anthesis to enlarged fruits. This two-dimensional data set provides a systems-level view of molecular events with precise spatial and temporal resolution.

Project description:To identify miRNAs involved in senescence of strawberry fruit, two independent small RNA libraries and one degradome library from strawberry fruits stored at 20 M-BM-0C for 0 and 24 h were constructed. A total of 18,759,735 and 20,293,492 mappable small RNA sequences were generated in the two small RNA libraries, respectively, and 88 known and 1224 new candidate miRNAs were obtained. Among them, 94 miRNAs were up-regulated and 64 were down-regulated in the senescence of strawberry fruit. Through degradome sequencing, 103 targets cleaved by 19 known miRNAs families and 55 new candidate miRNAs were identified. 14 targets, including NAC transcription factor, Auxin response factors (ARF) and Myb transcription factors, cleaved by 6 known miRNA families and 6 predicted candidates, were found to be involved in regulating fruit senescence. sample 1: Examination of small RNA in strawberry fruits stored at 20 M-BM-0C for 0; sample 2: Examination of small RNA in strawberry fruits stored at 20 M-BM-0C for 24 h

Project description:Background: MiRNAs and phasiRNAs are negative regulators of gene expression. These small RNAs have been extensively studied in plant model species but only 10 mature microRNAs are present in miRBase version 21 and no phasiRNAs have been identified for the legume model Phaseolus vulgaris. Thanks to the recent availability of the first version of the common bean genome, degradome data and small RNA libraries, we are able to present here a catalog of the microRNAs and phasiRNAs of this organism and, particularly, new protagonists of the symbiotic nodulation events. Results: We identified a set of 185 mature miRNAs, including 121 previously unpublished sequences, encoded by 307 precursors and distributed in 98 families. Degradome data allowed us to identify a total of 181 targets for these miRNAs. We reveal two regulatory networks involving conserved miRNAs, known to play crucial roles in the well-establishment of nodules, and novel miRNAs specific of the common bean suggesting a specific action of these sequences. In parallel, we identified 125 loci that potentially produce phased small RNAs and 47 of them present all the characteristics to be triggered by a total of 31 miRNAs, including 14 new miRNAs identified in this study. Conclusions: We provide here a set of new small RNAs, which contribute to the broader scene of the sRNAome of Phaseolus vulgaris. Thanks to the identification of the miRNA targets from degradome analysis and the construction of regulatory networks between the mature microRNAs, we draw up here the probable functional regulation associated with the sRNAome and particularly in N2-fixing symbiotic nodules.

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.
