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.
