Project description:We performed RNA-seq and Ribo-seq analyses to elucidate the translation in seeds at 85 and 115 DAF. We also completed a data-independent acquisition (DIA)-based proteomic analysis, while also examining relevant lipid metabolites.

Project description:Seeds germination is seriously sensitive to salt stress. The mechanism in response to salt stress during seed germination is still little known. In this study, two genotypes of hulless barley lk621 and lk53 were selected to investigate the molecular mechanism of seeds salinity response during germination stage through RNA-seq and iTRAQ technologies

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:To determine the effect of different temperature on strawberry after harvest, physiological indicator analysis and proteomics analysis were conducted on ripened strawberry (‘Sweet Charlie’) fruit stored at 4 °C, 23 °C, and 37 °C (±2) for 10 or 20 days. Results showed that 4 °C maintained a better visual quality of strawberry, and the weight loss and firmness remained stable within 3 days. Low temperature negatively affected anthocyanin but positively affected soluble sugars. Though anthocyanin content was higher with increasing temperature, anthocyanin synthesis related proteins were downregulated. Higher indole-acetic acid (IAA) content in seeds and lower abscisic acid (ABA) content were found in berry at 4 °C. Antioxidant related proteins were upregulated during storage, showing a significant up-regulation of POD at 4 °C, and AsA-GSH cycle related proteins and heat shock proteins (HSPs) at 37 °C. In addition, overexpressed sugar phosphate/phosphate translocator, 1-aminocyclopropane-1-carboxylate oxidase and aquaporin PIP2-2 had a positive effect in response to low temperature stress for containing higher protopectin content and POD activity.

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 °C 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.

Project description:Panax notoginseng (Burk) F.H. Chen is an importantly economical and medicinal plant of the family Araliacease, and its seeds are obviously characterized by the recalcitrance and after-ripening process. an isobaric tag for relative and absolute quantification (iTRAQ) and RNA-seq was used to analyze the proteomic changes and transcriptomic in seeds of P. notoginseng during the after-ripening process .

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.
