Comparative and evolutionary analysis of chloroplast genomes from five rare Styrax species.

ABSTRACT:

Background

Styrax, a vital raw material for shipbuilding, construction, perfumes, and drugs, represents the largest and most diverse genus in the Styracaceae. However, there is a relative scarcity of research on Styrax, particularly in evolution and genetics. Therefore, this study conducted comparative and evolutionary analyses of the chloroplast genomes of five rare Styrax species (S. argentifolius, S. buchananii, S. chrysocarpus, S. finlaysonianus, and S. rhytidocarpus).

Results

The results indicated that, despite high levels of conservation in chloroplast genome structure among these species, specific mutation hotspot regions exist, particularly involving the expansion and contraction of the IR region. Additionally, evidence of positive selection was detected in eight gen
