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.

Expression profiles of ABA treated bladder and leaf samples of Chenopodium quinoa

Project description:In this project, leaves and EBCs of the halophyte plant Chenopodium quinoa were treated with ABA. The effect of the ABA treatment was analyzed by comparing to non-treated leaves and EBCs.

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.

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.

The diversity of quinoa morphological traits and seed metabolic composition

Project description:<p>Quinoa (<em>Chenopodium quinoa</em> Willd.) is an herbaceous annual crop of the amaranth family (Amaranthaceae). It is increasingly cultivated for its nutritious grains, which are rich in protein and essential amino acids, lipids, and minerals. Quinoa exhibits a high tolerance towards various abiotic stresses including drought and salinity, which supports its agricultural cultivation under climate change conditions. The use of quinoa grains is compromised by anti-nutritional saponins, a terpenoid class of secondary metabolites deposited in the seed coat; their removal before consumption requires extensive washing, an economically and environmentally unfavorable process; or their accumulation can be reduced through breeding. In this study, we analyzed the seed metabolomes, including amino acids, fatty acids, and saponins, from 471 quinoa cultivars, including two related species, by liquid chromatography - mass spectrometry. Additionally, we determined a large number of agronomic traits including biomass, flowering time, and seed yield. The results revealed considerable diversity between genotypes and provide a knowledge base for future breeding or genome editing of quinoa.</p>
