Next-Generation Sequencing Facilitates Quantitative Analysis of Two Kinds of Chenopodium quinoa Transcriptomes

Project description:We generated 95.37 Gb of high-quality sequencing data (~7.95 Gb per sample). The analysis showed differences of transcriptomes between the common white sweet quinoa and the yellow bitter quinoa. We identified numerous differentially expressed genes that exhibited distinct expression patterns. These genes have known or potential roles in taste of quinoa fruit.Therefore, we are appealing candidates for further investigation of the gene expression and associated regulatory mechanisms related to the accumulation of bitter saponins in C. quinoa fruits.

Genome-wide analysis of CqCrRLK1Ls and CqRALFs in Chenopodium quinoa

Project description:Quinoa (Chenopodium quinoa) is a highly nutritious crop showing a remarkable tolerance to multiple abiotic stresses. The Catharanthus roseus RLK1-like kinase (CrRLK1L) family is involved in multiple processes during plant growth and stress responses. However, little is known about the members of the CqCrRLK1L subfamily and their biological functions. In this study, up to 26 CqCrRLK1L members were identified in quinoa genome. To systematically investigate their tissue-specific expression pattern and gene expression profiles in response to abiotic stresses, different quinoa samples including leaf, pistil, stamen, root, and leaf treated with NaCl were harvested for transcrioptome analysis with three biological replicates for each sample. Finally,we mapped about 30 million sequence reads per sample to the quinoa genome (NL-6) and combining the four different tissues (leaf, pistil, stamen, and root), totally 40382 genes were detected, accounting for 69% of total genes in quinoa. The expression of most CqCrRLK1Ls genes were detected in all four kind of tissues, and they showed tissue-specific expression pattern. In salt-treated leaves, we observe that about 6-thosands genes changed their expression, with log2FoldChange < -1 or >1 and p value <0.05. And four CqCrRLK1L genes largely altered their transcript levels, implying that these genes are involved in the regulation of salt stress response in quinoa. The present study provides a base for future research on elucidating the varied biological functions of CqCrRLK1Ls and their contributions to stress responses.

Quinoa gene expression under shoot or root heating

Project description:Quinoa is a highly nutritious seudocereal crop that is not well adapted to heat. Improving understanding of quinoa responses to heat would help expand its cultivation to regions with warmer climates. This study profiled gene expression of quinoa plants from accession QQ74 (PI 614886) treated with high tempreatures during anthesis of the main panicle, which lasted 11 days. Heat was applied in four different treatments to profile gene expression changes from root or shoot heating. Treatments were: 1. control with both roots and shoots at 22°C, 2. heated roots with roots at 30°C and shoots at 22°C, 3. heated shoots with roots at 22 °C and shoots at 35°C, and 4. heated roots and shoots with roots at 30°C and shoots at 35°C. Healthy leaves from 3 plants per treatment were sampled from the mid section of the plants, during the first (day 1) and last day (11) of heat treatment, at Zeitgeber time 2. Gene expression of each of the three heat treatments was compared to control using the Kallisto-Sleuth pipeline. These gene expression profiles of quinoa under heat are made available as a community resource to improve understanding of quinoa responses to heat.

Next Generation Sequencing Facilitates Quantitative Analysis of Chenopodium quinoa Transcriptomes

Project description:We generated 70.9 Gb of high-quality sequencing data (~7.88 Gb per sample) and catalogued the expression profiles of 54，238 annotated Chenopodium quinoa genes in each sample. These genes have known or potential roles in the roots, stems, and leaves of quinoa. Therefore, we are appealing candidates for further investigation of the gene expression and associated regulatory mechanisms.

Quinoa seed proteome - Characterization of quinoa seed proteome combining different protein precipitation techniques: Improvement of knowledge of nonmodel plant proteomics

Project description:A shotgun proteomics approach was used to characterize the quinoa seed proteome. To obtain comprehensive proteomic data from quinoa seeds three different precipitation procedures were employed: MeOH/CHCl3/ddH2O, acetone either alone or with trichloroacetic acid; the isolated proteins were then in-solution digested and the resulting peptides analyzed bynano liquid chromatography coupled to tandem mass spectrometry. However, since quinoa is a non model plant species, only a few protein sequences are included in the most widely known protein sequence databases. To improve the data reliability a UniProt subdatabase, containing only proteins of Caryophillales order, was used.

RNAseq of Quinoa salt bladders vs. leaves

Project description:Chenopodium quinoa, a pseudo-cereal and facultative halophyte, is a species of great economic potential. When exposed to saline soil, this salt-tolerant crop takes up sodium and chloride ions and sequesters large NaCl quantities in epidermal bladders cells (EBC). We have analyzed the Quinoa EBC transcriptome by RNA sequencing and elucidated the molecular identity and function of key ion transporters. Thereby we analyzed transcripts differentially expressed between EBCs and total leaves under control conditions.

Shotgun proteomics of quinoa seeds from plants grown under irrigated and rainfed conditions

Project description:Quinoa is an Andean crop whose cultivation has been extended to many different parts of the world in the last decade. It shows a great capacity for adaptation to diverse climate conditions, including environmental stressors, and moreover, the seeds are very nutritious in part due to their high protein content which is rich in essential amino acids. They also contain good amounts of other nutrients such as unsaturated fatty acids, vitamins, or minerals and are gluten-free seeds. Also, the use of quinoa hydrolysates and peptides has been linked to numerous health benefits. Altogether, these aspects have situated quinoa as a crop able to contribute to food security worldwide. Aiming to deepen our understanding of the protein quality and function of quinoa seeds and how they can vary when this crop is subjected to water-limiting conditions, a shotgun proteomics analysis was performed to obtain the proteomes of quinoa seeds harvested from two different water regimes in field: rainfed and irrigated conditions. Also, a quantitative analysis was developed to determine the total number of proteins identified in both samples, which of them are present in both conditions, and also, which ones were present exclusively in seeds under rainfed or irrigated conditions.

TMT proteomic analysis of tropical quinoa (Chenopodium quinoa willd.) seeds during maturation

Project description:Many limitation factors, such as seed pre-harvest sprouting, bitter saponin e.c., greatly restricts quinoa production and popularity. To solves these problems, the underlying mechanism of seed maturation in quinoa was required. In this study, morphological observation, TMT proteomics and parallel reaction monitoring (PRM) were conducted to investigate the variation of quinoa seed during seed maturation
