The availability of various versions of the L. japonicus genome, while proving to be an important resource in legume research, makes it difficult for users to map annotated genes and/or transcripts from one version to another. The Transcript Mapper (TRAM) tool can be used for exactly this purpose, and we currently support versions 2.5 and 3.0. As with all the other tooklits provided with Lotus Base, TRAM provides deep-linking to other tools for your convenience.
