Objective: This page is to track information related to the analysis of the Amborella genome.

Overview of polyploidy in the Angiosperms

Amborella lacks all the polyploidy events found in the other angiosperms. While there is evidence of an angioperm-specific polyploidy based on phylogenetic evidence from transcriptome analyses (http://www.nature.com/nature/journal/v473/n7345/abs/nature09916.html), there is no structural evidence identified from Amborella-Amborella syntenic dotplots.

Amborella lacks the eudicot paleohexaploidy

Grape-amborella

Amborella gene models are okay

Amborella gene models

Synteny with Rice

Amborella-rice

Syntenic with Aquilegia coerulea (columbine)

Appears to be a 1xAmborella:2xColumbine relationship:

Amborella-aquilegia

Some evidence of synteny with self-self comparison

Amborella-amborella

No evidence of synteny with Selaginella

Amborella-selaginella

Evidence for pre-angiosperm WGD

Ambo v. monocots
