Amborella trichopoda

An Evolutionary Reference Sequence

Amborella Flower

Welcome to the Amborella Genome Database

Welcome to the Amborella Genome Project!

On December 20, 2013, we published the draft genome sequence of Amborella trichopoda. Please visit the Data page to download the assembly and annotation. We also published a companion article on the novel assembly and validation methods used in our project.

Funded by the NSF Plant Genome Research Program, the Amborella Genome Sequencing Project aims to generate a high-quality draft genome sequence for Amborella trichopoda, the earliest diverging species on the flowering plant tree of life. Find out more about Amborella.

The genome sequence of Amborella trichopoda provides an evolutionary framework for comparative analyses of angiosperm gene content and genome structure. Among basal angiosperms, Amborella has the most extensive genomic resources, already possessing high-quality genomic libraries, a physical map, and a large expressed gene (transcriptome) database. These resources, along with its pivotal phylogenetic position and moderate genome size (870 million base pairs), make Amborella the singular choice for the first basal angiosperm to be fully sequenced. The Amborella Genome Project will 1) generate a high-quality draft genome sequence using a whole genome shotgun strategy; 2) improve the physical map of Amborella and integrate it with the genome sequence using cytogenetics and optical mapping; and 3) develop bioinformatic tools and a public-access website to display the project database as it is produced, and support comparative analyses and data mining by the scientific community at large.
