Complete chloroplast genome of Macadamia integrifolia confirms the position of the Gondwanan early-diverging eudicot family Proteaceae.

ABSTRACT:

Background

Sequence data from the chloroplast genome have played a central role in elucidating the evolutionary history of flowering plants, Angiospermae. In the past decade, the number of complete chloroplast genomes has burgeoned, leading to well-supported angiosperm phylogenies. However, some relationships, particulary among early-diverging lineages, remain unresolved. The diverse Southern Hemisphere plant family Proteaceae arose on the ancient supercontinent Gondwana early in angiosperm history and is a model group for adaptive radiation in response to changing climatic conditions. Genomic resources for the family are limited, and until now it is one of the few early-diverging 'basal eudicot' lineages not represented in chloroplast phylogenomic analyses.
