Non-target molecular network and putative genes of flavonoid biosynthesis in Erythrina velutina, a Brazilian semiarid native woody plant

ABSTRACT: Erythrina velutina is widely used in traditional medicine, being a source of specialized metabolites with anti-inflammatory and central nervous system modulatory activities. To date, the specialized metabolic network of the genus Erythrina and its regulation are missing, in part due to the lack of genomic information. In an effort to fill this knowledge gap, leaves and seeds had their metabolic and proteomic profiles (LC/MS) analyzed and integrated with transcriptome (RNA-seq) data. These data sets were obtained from plants growing in their harsh natural habitat and examined with emphasis on differentially expressed transcripts, transcription factors, and genes putatively involved in the biosynthesis of flavonoids, the most abundant metabolite class annotated. Of the 96 metabolites distributed in different classes found in this study, 28 and 30 were exclusively found in seeds and leaves, respectively, whereas 38 metabolites occurred in both structures. It was possible to assemble a set of 17,822 transcripts, of which 3,937 transcripts were differentially expressed (2,815 down- and 1,122 up-regulated). Candidate transcripts involved in flavonoid accumulation and transcription factors amounted to 28 and 394, respectively. Expression patterns of transcripts involved in flavonoid biosynthesis and its regulation, as well as those involved in responses to biotic and abiotic stresses, are discussed in detail. Hopefully, these findings will provide a solid base to further the understanding of the molecular and metabolic responses in this important medicinal plant species, as well as identify key regulatory targets for future studies aiming at bioactive metabolite production.

Project description:DM64 is a toxin-neutralizing serum glycoprotein isolated from the South American opossum Didelphis aurita. This ophiophagous marsupial is naturally resistant to snake envenomation and has evolved such biochemical defense as a trophic adaptation. The endogenous antitoxin is a human α1B-glycoprotein homolog of 64 kDa, specifically targeting myotoxic phospholipases A2, which account for most local tissue damage associated with viper snakebites. This study investigated the noncovalent complex formed between native DM64 and myotoxin II, a myotoxic calcium-independent phospholipase-like protein from Bothrops asper venom. Analytical ultracentrifugation, size exclusion chromatography, and small-angle X-ray scattering (SAXS) data indicated that DM64 is monomeric in solution and binds equimolar amounts of the toxin. Initial attempts to solve the structure of DM64 experimentally failed due to technical limitations caused by N-glycan heterogeneity and low recovery of heterologous protein. Classical molecular modeling techniques were impaired by the lack of templates with more than 25% sequence identity with DM64. An integrative structural biology approach was then applied to generate a refined three-dimensional model of the inhibitor bound to myotoxin II. The five immunoglobulin-like domains of DM64 were individually modeled using the I-TASSER suite. Distance constraints generated by cross-linking mass spectrometry of the complex guided the docking of DM64 domains to the crystal structure of myotoxin II (1CLP), using the Rosetta docking suite. The model of the DM64-myotoxin II complex was successfully fitted to a SAXS envelope. Inter-protein cross-links and limited hydrolysis analyses shed light on the inhibitor's regions involved with toxin interaction, revealing the critical participation of the first, third, and fifth domains of DM64. Our data showed that the fifth domain of DM64 binds to myotoxin II’s amino-terminal and -wing regions. The third domain of the inhibitor acts in a complementary way to the fifth domain. Their binding to these toxin regions presumably interferes with dimerization, a critical step in the allosteric activation of myotoxic PLA2-like proteins. Additionally, the first domain of DM64 likely interacts with the functional site of the toxin putatively associated with membrane anchorage. We propose that both mechanisms concur to effectively inhibit myotoxin II toxicity by DM64 binding. In summary, we argue such topological characterization of this toxin-antitoxin complex to constitute an essential first step toward the rational design of novel peptide-based antivenom therapies targeting snake venom myotoxins.

Project description:Jatropha curcas, a tropical shrub, is an attractive biofuel crop, which produces seeds with a high content of oil and protein. Most J. curcas accessions contain a range of toxins and anti-nutritional compounds, which are unfavorable for human consumption and animal feed. With the goal of better understanding the development of its seeds and to improve Jatropha`s agronomic performance, a two-step approach was performed: 1) generation of the entire transcriptome of six different developmental stages of J. curcas seeds using 454-Roche sequencing of a cDNA library, 2) comparison of transcriptional expression levels in six different developmental stages of seeds using a custom Agilent 8x60K oligonucleotide gene expression microarray. A total of 793,875 high quality reads with an average length of 358 bp were generated and assembled into 19,841 unique full-length contigs, of which 13,705 could be annotated with GO terms. Microarray data analysis identified a total of 9,111 contigs which were differentially expressed between the six developmental stages (based on P-value of < 1e-8). The microarray-based differential expression results were validated for 192 putative genes using high-throughput quantitative real-time PCR. Results from Gene Ontology (GO) and pathway enrichment analysis showed that the upstream biosynthesis pathways were relatively active among differentially expressed sequences (DESs) during seed development, such as starch and sucrose metabolism, glycolysis/gluconeogenesis, glycerophospholipid metabolism, amino sugar and nucleotide sugar metabolism. Further, DESs related to hormone and seed development, flavonoid biosynthesis-related pathways were over-represented. A pairwise comparison was used to discover particular seed maturation dependent patterns of gene expression. Genes related to fatty acid biosynthesis were over represented in early stage, while flavonoid biosynthesis in the late stage. The data provide a useful resources and references for the seed transcriptome of J. curcas and other related species with oil producing seeds. The identified transcripts related to seed development provide a starting point for further investigation into the molecular mechanisms underlying this process.

Project description:This is metabolic network reconstruction of Sulcia muelleri described in the article Graph-Based Analysis of the Metabolic Exchanges between Two Co-Resident Intracellular Symbionts, Baumannia cicadellinicola and Sulcia muelleri, with Their Insect Host, Homalodisca coagulata. Cottret L, Milreu PV, Acuña V, Marchetti-Spaccamela A, Stougie L, Charles H, Sagot MF. PLoS Comput Biol. 2010 Sep 2;6(9). pii: e1000904. PMID: 20838465 , DOI: 10.1371/journal.pcbi.1000904 Abstract: Endosymbiotic bacteria from different species can live inside cells of the same eukaryotic organism. Metabolic exchanges occur between host and bacteria but also between different endocytobionts. Since a complete genome annotation is available for both, we built the metabolic network of two endosymbiotic bacteria, Sulcia muelleri and Baumannia cicadellinicola, that live inside specific cells of the sharpshooter Homalodisca coagulata and studied the metabolic exchanges involving transfers of carbon atoms between the three. We automatically determined the set of metabolites potentially exogenously acquired (seeds) for both metabolic networks. We show that the number of seeds needed by both bacteria in the carbon metabolism is extremely reduced. Moreover, only three seeds are common to both metabolic networks, indicating that the complementarity of the two metabolisms is not only manifested in the metabolic capabilities of each bacterium, but also by their different use of the same environment. Furthermore, our results show that the carbon metabolism of S. muelleri may be completely independent of the metabolic network of B. cicadellinicola. On the contrary, the carbon metabolism of the latter appears dependent on the metabolism of S. muelleri, at least for two essential amino acids, threonine and lysine. Next, in order to define which subsets of seeds (precursor sets) are sufficient to produce the metabolites involved in a symbiotic function, we used a graph-based method, PITUFO, that we recently developed. Our results highly refine our knowledge about the complementarity between the metabolisms of the two bacteria and their host. We thus indicate seeds that appear obligatory in the synthesis of metabolites are involved in the symbiotic function. Our results suggest both B. cicadellinicola and S. muelleri may be completely independent of the metabolites provided by the co-resident endocytobiont to produce the carbon backbone of the metabolites provided to the symbiotic system (ie., thr and lys are only exploited by B. cicadellinicola to produce its proteins).

Project description:Background Grapes (Vitis vinifera L.) are economically the most important fruit crop worldwide. However, the complexity of molecular and biochemical events that lead to the onset of ripening of nonclimacteric fruits is not fully understood which is further complicated in grapes due to seasonal and cultivar specific variantion. The Portuguese wine variety Trincadeira gives rise to high quality wines but presents extremely irregular berry ripening among seasons probably due to high susceptibility to abiotic and biotic stresses. Results Ripening of Trincadeira grapes was studied taking into account the transcriptional and metabolic profilings complemented with biochemical data. The mRNA expression profiles of four time points spanning developmental stages from pea size green berries, through veraison and mature berries (EL 32, EL 34, EL 35 and EL 36) and in two seasons (2007 and 2008) were compared using the Affymetrix GrapeGen® genome array containing 23096 probesets corresponding to 18726 unique sequences. Over 50% of these probesets were significantly differentially expressed (1.5 fold) between at least two developmental stages. A common set of modulated transcripts corresponding to 5862 unigenes indicates the activation of common pathways in between years despite the irregular development of Trincadeira grapes. These unigenes were assigned in the functional categories of “metabolism, development”, “cellular process”, “diverse functions”, “regulation overview”, “response to stimulus, stress”, “signaling”, “transport overview”, “xenoprotein, transposable element” and “unknown”. Metabolic profiling using 1H NMR spectroscopy associated to two-dimensional techniques showed the importance of metabolites related to oxidative stress response, amino acid and sugar metabolism as well as secondary metabolism in grape ripening. This information was integrated with transcriptional profiling obtained using genome array and qRT-PCR for five developmental stages (EL 32, EL 34, EL 35, EL 36 and EL 38). Conclusions Altogether the results provide new information regarding the network of events leading to grape ripening as well as highlight features that may be cultivar specific namely in what concerns the role of carbohydrates and growth regulators´ metabolism as well as epigenetic factors and signaling pathways. 4 time points in 2007 season. 3 time points in 2008 season. 3 biological replicates.
