PlaNet database

Plant network and modeling database

More info
Plant Network and modeling database (PlaNet) is a resource of metabolic pathways in cassava and its molecular regulation such as transcriptional and translational regulation. For the first version, the useful information of carbon assimilation pathways in cassava (Manihot esculenta Crantz) reconstructed from comparative genomics approach using multi-plant templates is available here. The cassava metabolic network is composed of genes, enzymes, biochemical compounds for each biochemical reaction. Due to the complex of living organism, its phenotype is not only relied on metabolic regulation but other regulations are also important, namely transcriptional, post-transcriptional, translational and post-translational regulation. Therefore, more useful information will be further explored for the next version of PlaNet including transcriptional regulatory network (TRN), regulation of non-coding RNA, and protein-protein interaction (PPI) network, respectively.

MePPI-In

Genome-wide prediction of protein-protein interaction network of cassava using interolog-based method

More info
MePPI-In, Protein-protein interaction (PPI) network of cassava, was constructed based on interolog method. The predicted PPIs of cassava were inferred according to the information of seven plants: Arabidopsis (235,215 of PPIs in Arabidopsis used for this study), rice (76,829 of PPIs in rice used for this study), potato (42 of PPIs in potato used for this study), maize (25 of PPIs in maize used for this study), castor bean (10 of PPIs in castor bean used for this study), soybean (10 of PPIs in soybean used for this study) and poplar (8 of PPIs in poplar used for this study). MePPI-In is the first genome-wide PPI network of cassava that proposed up to 90,173 interactions of 7,209 proteins.

Carbon assimilation pathway of cassava

More info
The MeRecon pathway was reconstructed by using comparative genomics approach based upon six plant templates: Arabidopsis, rice, maize, castor bean, potato, and turnip. It consists of eight sub-metabolisms: Calvin cycle, sucrose biosynthesis, starch biosynthesis, respiration, amino acid biosynthesis, cell wall biosynthesis, fatty acid biosynthesis, and nucleotide biosynthesis sub-metabolisms visualized by SmartDraw. The reconstructed pathway maps can be download as below.

ph-MeRecon

The compartmentalized network of primary carbon metabolism in photosynthetic tissues of cassava

More info
The ph-MeRecon (photosynthetic-Manihot esculenta Metabolic Pathway Reconstruction) was constructed by integrating the genomic information and biochemical reactions of cassava, Arabidopsis, and rice into the genome-based pathway of primary metabolism in cassava, MeRecon (Siriwat, 2012). It comprises 461 metabolites, 550 reactions, and 1,037 metabolic genes. Enzymatic genes on the network were validated using RNA-expression data, and the reactions and pathways were compartmentalized into cytoplasm, chloroplast, mitochondria, and peroxisome.

DTScreen

Genome-scale screening tool for drug targets identification

More info
DTscreen v1 is a user-friendly and free bioinformatics tool, was developed for facilitating any researchers in biomedical field to perform a genome-scale screening for identifying all attractive drug targets against pathogenic diseases. The proposed drug targets were reported based on 1) non-homolog with human proteins in term of protein signatures and 2) gene essentiality reported from a large-scale wet experiment The tool was constructed in Visual Basic language and implemented as an application platform. DTscreen provides a fast and automated performance for identifying drug targets in the three model pathogenic bacteria, including Salmonella typhi CT18, Mycobacterium tuberculosis H37Rv and Escherichia coli K12-MG1655. Fortunately, users can apply DTscreen v1 to other interested pathogens by inserting required biological information of each pathogen.

VANTED-starch-synthesis-process

Metabolic pathways of starch biosynthesis in cassava

More info
The metabolic pathway of starch biosynthesis in cassava, including carbon dioxide fixation (Calvin cycle), sucrose synthesis and storage starch synthesis, were reconstructed based on the comparative genomics approach. The cassava genes comprised of the starch biosynthesis pathway were identified from their orthologues presented in the five template plants (i.e. Arabidopsis, rice, maize, castor bean, and potato). There constructed pathways were presented in both SmartDraw (an informative format of the pathway map) and VANTED (an interactive format of the pathway map for omics data integration) platforms. The reconstructed pathway maps and the other supplemental data of this work are ready to download.

VANTED-Carbon-assimilation-v1

Vanted carbon assimilation v1 Cassava metabolic pathway

More info
The reconstructed pathway can be used as a template to facilitate the omics data integration into the metabolic pathways. This cassava carbon assimilation pathway includes cell wall biosynthesis, starch biosynthesis, and respiration pathways. This work was presented in the Conference on Computational Systems-Biology and Bioinformatics (CSBio 2012), 3-5 October 2012, Centara Grand at Central Plaza Ladprao, Bangkok, Thailand in title of “Transcriptomic data integration inferring the dominance of starch biosynthesis in carbon utilization of developing cassava roots”, and was published in Elsevier Procedia Computer Science open access. Regarding the research work, the three key carbon metabolism pathways—cell wall biosynthesis, starch biosynthesis, and respiration pathway—were reconstructed following the protocol of Rongsirikul et al., 2010. In brief, the cassava metabolic pathways were reconstructed through comparative genomics approach (reciprocal BLASTp) using multiple plant templates: Arabidopsis, rice, maize, castor bean, and potato. The supplemental data infers the carbon partitioning during cassava root development at the transcriptional level—fibrous root (FR), developing storage root (DR), and mature storage root (MR) from Yang et al., 2011—was provided as the Appendix A.
