Project teams of the Gramene and MaizeGDB databases in collaboration with the Maize Genome Sequencing Project
Details of the changes introduced in this version of MaizeCyc may be found here.
Developed by personnel at the comparative genomics database Gramene and the maize model organism database MaizeGDB, in collaboration with the Maize Genome Sequencing Project (MGSC), MaizeCyc is a catalog of known and/or predicted metabolic and transport pathways from maize (Zea mays ssp. mays). Pathways and genes presented in this catalog are based on the electronic and manual annotations of the B73 RefGen_v2 gene models. It includes various sequence-based associations provided by Gramene, MaizeSequence.org, and MaizeGDB to external database entries from EntrezGene, UniProt-SwissProt and GenBank. Since version 2.0, manual annotations of genes include mapping of classical phenotype genes to sequenced genomic loci provided by Schnable and Freeling, proteomics-supported gene annotations from Friso et al (2010), and manual editing of about 180 gene names based on their homology to known enzymes from plant homologs. The database was created using the Pathway Tools PathoLogic module developed by Peter D. Karp and coworkers at the Bioinformatics Research Group at SRI International.
We welcome feedback from the research community to help us build a good quality network. You can reach us by sending a message to MaizeCyc curators or by clicking the 'Feedback' button at the top right corner of this page or on the bottom of the respective pathway display page.
MaizeCyc is based upon the BioCyc software. To learn how to use MaizeCyc, you can use the tutorials at BioCyc or the video tutorial developed for Gramene Pathways.
This work is supported by the NSF Plant Genome Research Resource grant award #0703908 (Gramene: A Platform for Comparative Plant Genomics) and the USDA-ARS (The Maize Genetics and Genomics Database).
