Plastome characterization and its phylogenetic implications on Lithocarpus (Fagaceae).

ABSTRACT:

Background

The genus Lithocarpus is a species-rich dominant woody lineage in East Asian evergreen broad-leaved forests. Despite its ecological and economic significance, the plastome structure and evolutionary history of the genus remain poorly understood. In this study, we comprehensively analyzed the 34 plastomes representing 33 Lithocarpus species. Of which, 21 were newly assembled. The plastome-based phylogenomic tree was reconstructed to reveal the maternal evolutionary patterns of the genus.

Results

The Lithocarpus plastomes exhibit a typical quadripartite structure, ranging in length from 161,010 to 161,476 bp, and containing 131 genes, including 86 protein-coding genes, 8 rRNA genes, and 37 tRNA genes. Remarkably, the infA gene was identified as a pseudogene in 17 sp
