Project description:Purpose:We aimed to characterize genome-widely the miRNA population and phasiRNA-generating genes/loci in litchi (Litchi chinensis). Multiple high throughput sequencing strategies, including sRNA sequencing, parallel analysis of RNA ends (PARE) sequencing, and strand-specific RNA-seq, were applied in combination with thorough bioinformatics analyses using a variety of computational methods.

Project description:Background: Litchi has high commercial value for its bright color and rich nutrients. However, it deteriorates with the pericarp turning brown within 1-2 days after harvest. The factors that mediate litchi fruit senescence are complicated. MicroRNAs act as negative regulators involving in almost every physiological process. To understand the mechanism of litchi fruit senescence and pericarp browning from miRNA level, five small RNA libraries and a degradome library from the pericarp of litchi fruit stored at ambient and post cold shelf-life were sequenced. Results: By aligning the sRNA reads onto litchi unigene assembly, 296 miRNAs belonging to 49 known miRNA families were first identified from litchi. In addition, eleven litchi-specific miRNAs were identified. Among these, 167 known miRNAs were identified to cleave 197 targets, and three litchi-specific miRNAs were found to have five targets. Through combined analysis of stem-loop quantitative real-time polymerase chain reaction (qRT-PCR) and transcriptome profiling, 14 miRNA-target pairs were found to be actively involved in litchi fruit senescence-related processes, including energy regulation, anthocyanin metabolism, hormone signaling, and pathogen-infection defense. Conclusions: A network of miRNA-target that regulates litchi fruit senescence has been proposed, revealing the miRNA-mediated regulation in senescent litchi fruit. This will aid to develop new strategies to postpone the senescence of litchi fruit and other horticultural products.

Project description:To improve the gene annotation and address a series of biological questions, we generated 490,502,822 clean reads of RNA-Seq data from nine tissue types of 'sijimi' longan, including root, stem, leaf, flower_bud, flower, young fruit, pericarp, pulp, and seed, and used them for mapping, and annotation of the longan genome sequence. About 53.55 ~79.40 % of the unique RNA sequences from nine RNA-seq data could be mapped to the genome. RNA-Seq data confirmed a majority of annotated introns, identified thousands of novel alternatively spliced mRNA isoforms, extend gene, SNP and indel, indicative of more functional variation than represented by the gene set alone, and a collection of potentially new and longan-specific gene. A comparative analysis of differential expression in the gene family at the nine different developmental stages showed that most of significant differentially expressed genes were mainly involved in the metabolic pathway, plant- pathogen interaction, and biosynthesis of secondary metabolities, which was fully consistent with the standpoint of D. longan specise containing a lot of plant pahtogen resistant genes, and in particular containing high levels of polyphenolic compounds

Project description:Lychee (Litchi chinensis Sonn.) is a popular fruit worldwide. Lychee downy blight, caused by Peronophythora litchii (P. litchii), is one of the major diseases in lychee. In this study, we conducted a P. litchii infection experiment on the lychee leaves of GW and SFZ, and analyzed the mRNA in the treated leaves using transcriptome RNA sequencing technology. Our research will provide a preliminary basis for the prevention and control of lychee downy blight.
