Project description:Ramie fibers extracted from the stem barks have been utilized for thousands years in China, and its biosynthetic mechanism is poorly understood. Here, we have characterized and compared the expression profiling of the barks from the top and middle part of stem where the secondary cellular walls (SCWs) of fiber cell have not initiated growth and was thickening, respectively; resulting in 4,520 differential expression (DE) protein-coding transcripts (PCTs), 1,287 DE long noncoding RNAs (lncRNAs), 88 DE miRNAs and 78 DE circular RNAs (circRNAs). Among the 4,520 DE PCTs, 75 were identified to be the homolog of the Arabidopsis SCW-biosynthetic genes. Overexpression of whole_GLEAN_10014861 (a homolog of SND1) in Arabidopsis caused a significant up-regulation in the expression of AtMYB46 and AtMYB83 that are two key regulators for SCW biosynthesis, thus conferring more fiber cells, along with a remarkable thickening in the SCWs of these cells. Bioinformatic prediction revealed 14 of the 75 homolog targeted by 16 noncoding RNAs (including 8 miRNAs and 8 lncRNAs), and two involved in the competing endogenous RNAs networks, indicating a complex regulatory network for the SCW biosynthesis of bast fiber in ramie. This study provides important insights into the bast fiber biosynthesis of ramie.

Project description:According to a previous study on the microscopic examination of stem barks in ramie, bast fibers from different parts of stem bark showed distinct differences at the developmental level: specifically, the barks in the top part of stem (TPS) did not initiate fiber growth, whereas barks in the middle part of stem (MPS) had a large number of fibers with thickening secondary walls. We have performed the Proteome analysis for the tissues of TPS and MPS, and then carried out the comparison of Proteomic level of proteins between two tissues, thereby to identified differentially Proteomic proteins. These datasets represent the raw UHPLC spectra for Proteome of ramie TPS and MPS.

Project description:Transcriptome analysis of root development related genes in terrestrial and hydroponic ramie. Ramie seedlings were cultivated in soil, and in hydroponic with the shoot-cutting propagation method. The root samples from hydrophonic ramie were collected from the early stage (5-day-old seedling) and the late stage (30-day-old seedling) of acquatic roots induction. The roots of ramie seedling cultivated in soil were also collected for comparative analysis. Our study represents the detailed analysis of ramie root transcriptomes with biologic replicates.

Project description:Drought is a main environment stress which severely inhibits the stem growth of ramie and lead to a decrease of the fiber yield. The mechanisms of ramie responding to drought stress are poorly understood. Using Illumina sequencing, approximately 4.8 million (M) 21-nt cDNA tags were sequenced in the cDNA library derived from the drought-stressed ramie (DS), and about 4.7 M were sequenced in the cDNA library constructed from the control ramie under well water condition (CO). The tags generated from two libraries were aligned with ramie transcriptome to annotate their function and a total of 23,912 and 22,826 ramie genes were matched by these tags of DS and CO library, respectively. Comparison of gene expression level between CO and DS ramie based on the differences of tag frequencies appearing in two libraries revealed that 1101 and 505 genes were respectively up- and down- regulated under drought stress. Pathway enrichment analysis identified a set of significantly enriched pathways of DEGs. A series of candidate genes and pathways that may contribute to drought tolerance in ramie will be helpful for further improving ramie drought tolerance ability.

Project description:Cadmium (Cd)-contamination in soil has been becoming a major environmental problem in China. Ramie, a fiber crop, was frequently proposed to be used as the crop for phytoremediation of Cd-contaminated farmlands. However, high level Cd accumulation can cause a great inhibition of growth in ramie. To understand the potential mechanism for this phenomenon, the ramie genes involved in the Cd stress response were identified using Illumina pair-end sequencing in two Cd-stressed plants (CdS1 and CdS2) and two control plants (CO1 and CO2) in this study. Approximately 48.7, 51.6, 41.2, and 47.1 million clean sequencing reads generated from the libraries of CO1, CO2, CdS1, and CdS2, respectively, were De novo assembled to yield 56,932 non-redundant unigenes. A total of 26,686 (46.9%) genes were annotated for their function. Comparison of gene expression levels between CO and CdS ramie revealed 155 differentially expressed genes (DEGs). Sixteen DEGs was further confirmed their expression difference by real-time quantitative PCR (qRT-PCR). Among these 16 DEGs, 2 genes encoding GA2-oxidase which is a major enzyme for deactivating bioactive gibberellins (GAs) were found with a markedly up-regulated expression, which is possibly responsible for the growth inhibition of Cd-stressed ramie. Pathway enrichment analysis revealed that a pathway (Cutin, suberine and wax biosynthesis) was markedly enriched by DEGs. The discovery of these Cd stress-responsive genes and pathways will be helpful for further understanding the mechanism of Cd-stressed response and improving the ability of Cd stress tolerance in ramie.
