The Genome of Medicinal Plant Macleaya cordata Provides New Insights into Benzylisoquinoline Alkaloids Metabolism

ABSTRACT: The overuse of antibiotics in animal agriculture and medicine has caused a series of potential threats to public health. Macleaya cordata is a medicinal plant species from the Papaveraceae family, providing a safe resource for the manufacture of antimicrobial feed additive for livestock. The active constituents from M. cordata are known to include benzylisoquinoline alkaloids (BIAs) such as sanguinarine (SAN) and chelerythrine (CHE), but their metabolic pathways have yet to be studied in this non-model plant. The active biosynthesis of SAN and CHE in M. cordata was first examined and confirmed by feeding 13C-labeled tyrosine. To gain further insights, we de novo sequenced the whole genome of M. cordata, the first to be sequenced from the Papaveraceae family. The M. cordata genome covering 378 Mb encodes 22,328 predicted protein-coding genes with 43.5% being transposable elements. As a member of basal eudicot, M. cordata genome lacks the paleohexaploidy event that occurred in almost all eudicots. From the genomics data, a complete set of 16 metabolic genes for SAN and CHE biosynthesis was retrieved, and 14 of their biochemical activities were validated. These genomics and metabolic data show the conserved BIA metabolic pathways in M. cordata and provide the knowledge foundation for future productions of SAN and CHE by crop improvement or microbial pathway reconstruction.

Project description:Archer2011 - Genome-scale metabolic model of Escherichia coli (iCA1273) This model is described in the article: The genome sequence of E. coli W (ATCC 9637): comparative genome analysis and an improved genome-scale reconstruction of E. coli. Archer CT, Kim JF, Jeong H, Park JH, Vickers CE, Lee SY, Nielsen LK. BMC Genomics 2011; 12: 9 Abstract: BACKGROUND: Escherichia coli is a model prokaryote, an important pathogen, and a key organism for industrial biotechnology. E. coli W (ATCC 9637), one of four strains designated as safe for laboratory purposes, has not been sequenced. E. coli W is a fast-growing strain and is the only safe strain that can utilize sucrose as a carbon source. Lifecycle analysis has demonstrated that sucrose from sugarcane is a preferred carbon source for industrial bioprocesses. RESULTS: We have sequenced and annotated the genome of E. coli W. The chromosome is 4,900,968 bp and encodes 4,764 ORFs. Two plasmids, pRK1 (102,536 bp) and pRK2 (5,360 bp), are also present. W has unique features relative to other sequenced laboratory strains (K-12, B and Crooks): it has a larger genome and belongs to phylogroup B1 rather than A. W also grows on a much broader range of carbon sources than does K-12. A genome-scale reconstruction was developed and validated in order to interrogate metabolic properties. CONCLUSIONS: The genome of W is more similar to commensal and pathogenic B1 strains than phylogroup A strains, and therefore has greater utility for comparative analyses with these strains. W should therefore be the strain of choice, or 'type strain' for group B1 comparative analyses. The genome annotation and tools created here are expected to allow further utilization and development of E. coli W as an industrial organism for sucrose-based bioprocesses. Refinements in our E. coli metabolic reconstruction allow it to more accurately define E. coli metabolism relative to previous models.

Project description:Background The number of managed honey bee colonies has considerably decreased in many developed countries in recent years and the ectoparasitic mites are considered as major threats to honey bee colonies and health. However, their general biology remains poorly understood. Results We sequenced the genome and transcriptomes of Tropilaelaps mercedesae, the prevalent ectoparasitic mite infesting honey bees in Asia. The de novo assembled genome sequence (353 Mb) represents 53% of the estimated genome size because of the compression of repetitive sequences; nevertheless, we predicted 15,190 protein-coding genes which were well supported by the mite transcriptomes and proteomic dataes. Although amino acid substitutions have been accelerated within the conserved core genes in of two mites, T. mercedesae and Metaseiulus occidentalis, T. mercedesae has undergone the least gene family expansion and contraction between the seven arthropods we tested. The number of sensory system genes has been dramatically reduced; meanwhile, T. mercedesae may have evolved a specialized cuticle and water homeostasis mechanisms, as well as epigenetic control of gene expression for ploidy compensation between males and females., and water homeostasis. T. mercedesae contains all gene sets required to detoxify xenobiotics, enabling it to be miticide resistant. T. mercedesae is closely associated with a symbiotic bacteriuma (Rickettsiella grylli-like) and DWVdeformed wing virus (DWV), the most prevalent honey bee virus. The presence of DWV in both adult male and female mites was also confirmed by the proteomic analysis. Conclusions T. mercedesae has a very specialized life history and habitat as the ectoparasitic mite strictly dependsing on the honey bee inside the a stable colony. Thus, comparison of the genome and transcriptome sequences with those of a tick and free-living mites and tick has revealed the specific features of the genome shaped by interaction with the honey bee and colony environment. T. mercedesae, as well as Varroa destructor, genome and transcriptome sequences not only provide insights into the mite biology, but may also help to develop measures to control the most serious pests of the honey bee.
