The complete chloroplast genome and phylogenetic analysis ofManglietia ventii(Magnoliaceae)

Abstract

Manglietia ventii is a highly ornamental timber tree species that is listed as endangered on the IUCN Red List. This study was conducted on the complete chloroplast genome of M. ventii. The length of the chloroplast genome is 159,950 bp with GC content as 39.3%. One hundred and thirty-one functional genes were identified in the genome, which included 86 protein-coding genes (PCGs), 37 tRNA genes, and eight rRNA genes. The phylogenetic analysis indicated that M. ventii is most closely related to M. megaphylla and M. aromatica , and the study provides new insights into the evolution of the Magnoliaceae.

Comparative Analysis of the Chloroplast Genomes of Eight Species of the Genus Lirianthe Spach with Its Generic Delimitation Implications

“…A total of 17 genera are recognized in Xia's system [6] and a total of 15 genera are recognized in Sima and Lu's system [7]. The system by Sima and Lu, based on the data on DNA and the observations of morphological characters, especially in living plants, is strongly supported by recent DNA work [21,23,30,32,41] and has been accepted by many scholars [11][12][13][14]. In order to better reflect the evolutionary steps and levels of Magnoliaceous plants, as well as the evolutionary trends and migration routes based primarily on morphological-geographical studies, it is a more feasible and useful approach to define smaller independent genera.…”

“…Li [ 9 ] prefer the treatment of segregated or smaller genera in the family Magnoliaceae because that the treatment of the bigger genera cannot represent the later evolution process and levels in this family, and that the bigger genera are too inclusive to reflect the evolutional trends and the migratory routes mainly on the basis of morpho-geographical studies. Sima and Lu’s Magnoliaceae system [ 7 , 10 ], established in 2012 based on DNA data and morphological characteristics, especially observations on living plants, consists of 14 monophyletic genera in their delimitation of the subfamily Magnolioideae, which has been strongly supported by an increasing number of DNA data analysis results and gradually accepted by many scholars [ 11 , 12 , 13 , 14 ].…”

Comparative Analysis of Chloroplast Genomes for the Genus Manglietia Blume (Magnoliaceae): Molecular Structure and Phylogenetic Evolution

“…These investigations significantly advanced our understanding of plant evolutionary relationships. However, the plastomes of many species of Manglietia are only published in the form of data, and scientific problems such as structural variation and evolutionary relationships among lineages have not been discussed [23,48]. Given their significant scientific and economic value, further exploration employing chloroplast genomes would provide crucial insights into the systematics and evolution of the family Magnoliaceae [11].…”
