Lotus japonicus Genome ?

View a sample region of chromosome 1 or select a region above:

Genome / Gene Models

The current genome assembly displayed at LjGDB is version Lj 1.0. Annotated gene models are Lj 1.0. For more information see Data & Methods. More about the genome...

Alignments to Genome

LjGDB displays high quality spliced alignments for EST, cDNA, PUT, and model species proteins. The current alignment database version is LjGDB171. For more information see Data & Methods. More about alignments...

Search / Download

Search or download any sequence from LjGDB using Search / Download links at left. Complete datasets can also be downloaded from the LjGDB Download page or by ftp. More about search / download...

Note: sequences displayed here may not reflect the latest Lotus japonicus sequence count at PlantGDB, which can be viewed on our download page.


Sequence analysis tools accessed from the Genome Context View menu use the current genomic region as input. Or, to access the same tools without a genomic context, use LjGDB left menubar Tools links. More about tools...

Gene Structure Annotation

Help annotate the Lotus japonicus genome using our yrGATE gene structure annotation tool (see Overview), aided by GAEVAL tables that flag problematic gene models. Video demo: QuickTime   Flash  

Custom Track Display

Distributed Annotation Service (DAS) (see Overview) is available for displaying remotely served genome alignments at LjGDB, as well as for displaying selected LjGDB tracks on a different genome browser (e.g. Ensembl, GBrowse). How to use DAS...

Additional custom track display features are under development.

Annotated Protein Alignments

A searchable table of splice-aligned, annotated protein models from one or more related species. Select from the left menu under Gene Annotations -> Splice-Aligned Proteins.

LjGDB is being developed as a part of our NSF-funded project "Cyberinfrastructure for (Comparative) Plant Genome Research Through PlantGDB" (PI: Volker Brendel). The purpose of this resource is to provide a convenient sequence-centered genome view for Lotus japonicus, with a narrow focus on gene structure annotation.
