Comparative chloroplast genomics reveals the phylogeny and the adaptive evolution of Begonia in China.

ABSTRACT:

Background

The Begonia species are common shade plants that are mostly found in southwest China. They have not been well studied despite their medicinal and decorative uses because gene penetration, decreased adaptability, and restricted availability are all caused by frequent interspecific hybridization.

Result

To understand the patterns of mutation in the chloroplast genomes of different species of Begonia, as well as their evolutionary relationships, we collected seven Begonia species in China and sequenced their chloroplast genomes. Begonia species exhibit a quadripartite structure of chloroplast genomes (157,634 - 169,694 bp), consisting of two pairs of inverted repeats (IR: 26,529 - 37,674 bp), a large single copy (LSC: 75,477 - 86,500 bp), and a small single copy (SSC
