NCBI, the national sight loss agency, is a not for profit charitable organisation which provides support and services nationwide to people experiencing sight loss.

We also provide a range of services to public and private organisations to make sure that their services are accessible to people who are blind and vision impaired.


Tools and resources for plant genomic.


EMBL is at the forefront of innovation in life sciences research, technology development and transfer, and provides outstanding training and services to the scientific community in its member states. This publicly-funded non-profit institute is housed at five sites in Europe whose expertise covers the whole spectrum of molecular biology.


Phytozome is a joint project of the Department of Energy's Joint Genome Institute and the Center for Integrative Genomics to facilitate comparative genomic studies amongst green plants. Famlies of orthologous and paralogous genes that represent the modern descendents of ancestral gene sets are constructed at key phylogenetic nodes. These families allow easy access to clade specific orthology/paralogy relationships as well as clade specific genes and gene expansions. As of release v9.1, Phytozome provides access to forty-one sequenced and annotated green plant genomes which have been clustered into gene families at 20 evolutionarily significant nodes. Where possible, each gene has been annotated with PFAM, KOG, KEGG, and PANTHER assignments, and publicly available annotations from RefSeq, UniProt, TAIR, JGI are hyper-linked and searchable.


MaizeGDB is a community-oriented, long-term, federally funded informatics service to researchers focused on the crop plant and model organism Zea mays.


Rice is a major food staple for the world's population and serves as a model species in cereal genome research. The Beijing Genomics Institute (BGI) has long been devoting itself to sequencing, information analysis, and biological research of the rice genome. Our Rice Information System (BGI-RIS) is targeted to be the most up-to-date integrated information resource for rice genomes as well as a workbench for comparative genomic analysis among cereal crops.

In addition to the comprehensive data of Oryza sativa L. ssp. indica sequenced by BGI, BGI-RIS will host carefully curated genome information of Oryza sativa L. ssp. japonica (Syngenta) since we have obtained permission from Syngenta to release their data as soon as related paper is published.

In BGI-RIS, sequence contigs of Beijing indica and Syngenta japonica have been further assembled and anchored onto the rice chromosomes. We have annotated the rice genomes for gene content, repetitive elements, and SNPs. Sequence polymorphisms between different rice subspecies have also been identified. Designed as a basic platform for rice study, BGI-RIS presents the sequenced genomes and related information in systematic and graphical ways for the convenience of in-depth comparative studies.

ThWheat A Genome

The wheat A genome, as a basic genome of bread wheat and other polyploid wheats, is centrally important to the evolution, domestication, and genetic improvement of wheat. The progenitor of the A genome is the diploid wild einkorn wheat Triticum urartu. Here, we sequenced T. urartu (accession G1812) using a whole-genome shotgun strategy on the Illumina HiSeq 2000 platform, and assembled the genome using SOAPdenovo2 with 448.49 Gb of filtered high-quality sequence data. The genome assembly reached 3.92 Gb (without Ns) with a contig N50 length of 3.42 kb and 4.66 Gb (with Ns) with a scaffold N50 length of 63.69 kb . To facilitate gene prediction, we generated a 116.65 Mb transcriptome of T. urartu with 67.14 Gb RNA-Seq data from eight different tissues and treatments, and 49,935 assembled transcripts from six tissues using the Roche 454 sequencing platform. In total, we predicted 34,879 protein-coding gene models. The average gene size was 3,207 bp, with a mean of 4.7 exons per gene.
