Evolutionary System of Magnoliaceae Based on Chloroplast Genomic and Morphological Evolutionomy

Da-Li Fu,
Hao Fu,
Run-Mei Duan
et al.

Abstract: Magnoliaceae Juss. are the most primitive taxa of Fructophyta D. L. Fu & H. Fu and have extremely important scientific values for the research of evolutionomy of fruit plants. Based on the evolutionary analysis of the complete chloroplast genomes of representative plants of Magnoliaceae in the NCBI (National Center for Biotechnology Information, USA) database, this paper firstly established the evolutionary systems of subgenera and sections of <i>Magnolia</i> L. and that of sect… Show more

“…The evolutionary analyses of CPCG mainly use the typical algorithm [1,[25][26][27] to determine the relative evolutionary relationships between different taxa by comparing the phylogenetic similarity (PHS) between the designated type and target taxa. The formula is as follows: PHS = phylogenetic similarity between the type and objective taxon; SPHL = the number of same phylogenetic loci between the type and objective taxon; APHL = the number of all phylogenetic loci of the type; statistics of phylogenetic loci using Nucleotide Barcodes (17bp).…”

“…The boundary for genus classi-fication is PHS (phylogenetic similarity, 17bp) ≥ 0.9234 (intragenus) or PHS (17bp) ≤ 0.9232 (inter genera). Magnoliaceae are the most primitive taxa among fruit plants and hold significant implications for evolutionary studies [34][35]. Therefore, we propose that the minimum criterion for classifying Fructophyta D.L.Fu & H.Fu [31] at the genus rank using CPCG data should be set as PHS ≤ 0.928 (inter genera), considering that two species of Liriodendron L. have a PHS value of 0.929 [34][35].…”
