The Arabidopsis Information Portal is an open-access online community resource for Arabidopsis research. AIP enables biologists to navigate from the Arabidopsis thaliana Col-0 reference genome sequence to its associated annotation including gene structure, gene expression, protein function, and interaction networks. AIP was funded in 2013 and came on line in 2014. AIP already offers a single interface through which to access a wide range of Arabidopsis information. AIP will grow through contributions of other labs in the form of modules: data, computation, and visualization tools.
