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:For exploring whether mRNA m6A modification participates in the regulation of strawberry fruit ripening, we performed m6A-seq in woodland strawberry fruit at three different development stages, including the S6 stage (almost 15 days post-anthsis (DPA)), the RS1 stage (21 DPA), and the RS3 stage (27 DPA), with three biological replicates. mRNA methylome analysis reveals that m6A methylation prevalently distributes in the strawberry transcriptome and highly enrichs in the coding sequence, stop codon and 3’ untranslated region.

Project description:‘Crumbly’ fruit is a developmental disorder in red raspberry (Rubus idaeus) that results in malformed fruit with poor adherence of drupelets to one another. In terms of quality and yield, crumbly fruit has become a serious problem in the raspberry industry resulting in unsaleable fruit and waste. A microarray experiment, using pools of progeny from a segregating mapping population (Glen Moy x Latham) with either 'normal' or 'crumbly' fruit at three different fruit developmental stages ('closed'; 'open'; 'green'), identified several genes that were differentially expressed between the crumbly and non-crumbly phenotypes within three quantitative trait loci (QTL) identified. Analysis of gene function highlighted the importance of processes that compromise ovule fertilization as triggers of the crumbly fruit phenotype.

Project description:Histone modifications mediate between genes and environment in plant growth and developmental events. To characterize the histone modification signatures in strawberry, we performed ChIP-seq experiments for seven histone marks in the immature and mature fruits, and leaves of the woodland strawberry F. vesca ('Ruegen'). The seven histone marks include H3K9/K14ac, H3K27ac, H3K4me1, H3K4me3, H3K36me3, H3K27me3 and H3K9me2. In addition, to reveal the effect of the histone deacetylase FvHDA6, H3K9/K14a was profiled in FvHDA6-OE fruits.

Project description:With the development of high throughput sequencing technologies, plenty of non-coding RNAs (ncRNAs) have been discovered to play important roles in diverse plant biological processes. Although these ncRNAs extensively exist in plant, their biological functions are still remained to characterize. To obtain a comprehensive understanding of long non-coding RNA (lncRNA) function in strawberry fruit ripening progress, we performed transcriptomic analyses on the diploid strawberry Fragaria vesca in a time-course during fruit ripening. Here, we have identified 25,613 lncRNAs based on RNA-seq data from poly(A)-depleted libraries and rRNA-depleted libraries. Among them, most of lncRNAs exhibit stage-specific expression pattern. Functional analysis on F.vesca endogenous FRUIT RIPENING-RELATED LONG ANTISENSE INTERGENIC RNA (FRILAIR) in octaploid strawberry Falandi, we found that overexpression FRILAIR can compete miR397 to regulate its target laccase genes (LACs), and it may contribute to strawberry ripening. Our findings demonstrate that FRILAIR can act as a competing endogenous RNA (ceRNA) by disturbing miR397 to repress expression level of LACs, and would be valuable for strawberry ripening.

Project description:The aim of this study was to determine the role of genes encoding polygalacturonases in strawberry fruit softening. To this purpose, several transgenic lines, cv. Chandler, were generated: plants with PG genes FaPG1 or FaPG2 downregulated, alone or in combination, by antisense transformation. Plants were grown in a confined greenhouse and fruits were harvested at the stage of full ripeness (100% of fruit surface red). The results obtained indicate that the silencing of these genes reduced fruit softening at similar level but there is not a sinergistic effect on fruit firmness.

Project description:We used Illumina sequencing to investigate the global transcriptomic expression of hormonal pathway genes in ABA initiated strawberry receptacle ripening. Expression profiles of hormone synthetic and signaling genes further demonstrated the positive roles of ABA and GA, and the negative role of auxin in receptacle ripening. We also evaluated the transcript profiling of ethylene and JA pathway genes, and the results suggested that both ethylene and JA participated in receptacle ripening. Furthermore, two novel miRNAs and three conserved miRNAs were identified and validated to target genes in ABA and auxin pathways, respectively. Our analyses reveal the molecular mechanism of hormonal regulation during strawberry receptacle ripening. The data also provide an abundant of genetic information for molecular manipulation on non-climacteric fruit ripening. Sample 1: CK0 (Strawberry fruit two weeks after athesis treated with water, set as day 0); Sample 2: CK5 (fruit treated with water on day 5); Sample 3: CK8 (fruit treated with water on day 8); Sample 4: ABA5 (fruit treated with ABA on day 5); Sample 5: ABA8 (fruit treated with ABA on day 5); Sample 6: NDGA5 (fruit treated with water on day 5); Sample 7: NDGA8 (fruit treated with NDGA on day 8).

Project description:In contrast to climacteric fruits such as tomato, the knowledge on key regulatory genes controlling the ripening of strawberry, a non-climacteric fruit, is still limited. NAC transcription factors mediate different developmental processes in plants. Here, we identified and characterized FaRIF (Ripening Inducing Factor), a NAC transcription factor that is highly expressed and induced in strawberry receptacles during ripening. Functional analyses based on stable transgenic lines aimed at silencing FaRIF by RNA interference, either from a constitutive promoter or the ripe receptacle-specific EXP2 promoter, as well as overexpression lines showed that FaRIF controls critical ripening-related processes such as fruit softening and pigment and sugar accumulation. Physiological, metabolome and transcriptome analyses of receptacles of FaRIF-silenced and overexpression lines point to FaRIF as a key regulator of strawberry fruit ripening from early developmental stages, controlling abscisic acid (ABA) biosynthesis and signaling, cell wall degradation and modification, the phenylpropanoid pathway, volatiles production, and the balance of the aerobic/anaerobic metabolism. FaRIF is therefore a target to be modified/edited to control the quality of strawberry fruits.
