Project description:Transcriptome analyses on seeds developed in different parental conditions investigating the effect of the parental environment on the transcriptome of dry seeds of three different genotypes RNA isolated from freshly harvested dry seed of three genotypes, the near isogenic line of DELAY OF GEMRMINATION 1 (DOG1), DOG3 and DOG6, grown in 15°C, 20°, low nitrate (N0), low light (LL) and SL (standard light). Please note that SL (standard light) is the control for the LL (low light), and 20C is the control for both 15C and low nitrate (N0).
Project description:Hemp (Cannabis sativa L.) is a widely researched industrial crop with a variety of applications in the pharmaceutical, nutraceutical, food, cosmetic, textile, and materials industries. Although many of these applications are related to its chemical composition, the chemical diversity of the hemp metabolome has not been explored in detail and new metabolites with unknown properties are likely to be discovered. In the current study, we explored the chemical diversity of the hemp seed metabolome through an untargeted metabolomic study of 52 germplasm accessions to 1) identify new metabolites and 2) link the presence of biologically important molecules to specific accessions on which to focus on in future studies. Multivariate analysis of mass spectral data demonstrated large variability of the polar chemistry profile between accessions. Five main groups were annotated based on their similar metabolic fingerprints. The investigation also led to the discovery of a new compound and four structural analogues, belonging to a previously unknown chemical class in hemp seeds: cinnamic acid glycosyl sulphates. Although variability in the fatty acid profiles was not as marked as the polar components, some accessions had a higher yield of fatty acids, and variation in the ratio of linoleic acid to α-linolenic acid was also observed, with some varieties closer to 3:1 (reported as optimal for human nutrition). We found that that cinnamic acid amides and lignanamides, the main chemical classes of bioactive metabolites in hemp seed, were more concentrated in the Spanish accession Kongo Hanf (CAN58) and the French accession CAN37, while the Italian cultivar Eletta Campana (CAN48) demonstrated the greatest yield of fatty acids. Our results indicate that the high variability of bioactive and novel metabolites across the studied hemp seed accessions may influence claims associated with their commercialization and inform breeding programs in cultivar development.
Project description:Genes controlling differences in seed longevity between two barley (Hordeum vulgare) accessions were identified by combining a quantitative genetics approach with ˈomicsˈ technologies in Near Isogenic Lines (NILs). The NILs were derived from crosses between the spring barley landraces L94 from Ethiopia and Cebada Capa from Argentina, which produce short-lived and long-lived seeds, respectively. The NILs harbor introgressions from Cebada Capa in four QTLs for seed longevity on 1H and 2H in the background of L94. A label-free proteome analysis was performed on mature, non aged seeds of the two parental lines and the L94 NILs.
Project description:Untargeted metabolomic analyses were carried out on seed coat/endosperm and seed embryo (dry seeds) of Arabidopsis thaliana Columbia-0 genotype. Three biological replicates were analyzed for each sample.

Project description:Cultivated soybean has domesticated in China for a long history, and there are several significant phenotypic differences between wild and cultivated soybeans. Seed of cultivar is generally larger than wild soybean, therefore here we comprehensively analyzed transcriptomes of thirteen soybean accessions seeds including seven wild soybeans and six landraces through applying strand-specific RNA sequencing. Differential expressed genes related seed weight were identified, some of them were known to be associated with seed development in Arabidopsis. Noncoding RNAs are known to play important roles in plant development, and we profiled the expression pattern of long noncoding RNA (lncRNA) in cultivated and wild soybean seeds. We have identified 1,251 long intergenic noncoding RNA, 243 intronic RNA and 81 antisense lncRNA, transcriptional levels of a number of lncRNAs were significantly different between cultivated and wild soybeans, suggesting that lncRNA may be involved in soybean seed development.
