Complete plastome sequence of Thalictrum coreanum (Ranunculaceae) and transfer of the rpl32 gene to the nucleus in the ancestor of the subfamily Thalictroideae.

ABSTRACT:

Background

Plastids originated from cyanobacteria and the majority of the ancestral genes were lost or functionally transferred to the nucleus after endosymbiosis. Comparative genomic investigations have shown that gene transfer from plastids to the nucleus is an ongoing evolutionary process but molecular evidence for recent functional gene transfers among seed plants have only been documented for the four genes accD, infA, rpl22, and rpl32.

Results

The complete plastid genome of Thalictrum coreanum, the first from the subfamily Thalictroideae (Ranunculaceae), was sequenced and revealed the losses of two genes, infA and rpl32. The functional transfer of these two genes to the nucleus in Thalictrum was verified by examination of nuclear transcriptomes. A survey of the phyloge
