The complete chloroplast genome of a new candidate cultivar, Sang Jae, of Abeliophyllum distichum Nakai (Oleaceae): initial step of A. distichum intraspecies variations atlas.

ABSTRACT: Chloroplast genome of Sang Jae, new candidate cultivar of Abeliophyllum distichum Nakai, has been sequenced to reveal infraspecific relationship of wildtypes and cultivars. Its length is 156,008?bp long (GC ratio is 37.8%) and has four subregions: 86,773?bp of large single copy (35.8%) and 17,827?bp of small single copy (31.9%) regions are separated by 25,704?bp of inverted repeat (43.2%) regions including 133 genes (87 protein-coding genes, eight rRNAs, and 37 tRNAs). Phylogenetic trees show that A. distichum is clustered with twelve Forsythia species and intraspecies variations level is similar to Olea europaea.

Project description:Background/objectivesAbeliophyllum distichum is a plant endemic to Korea, containing several beneficial natural compounds. This study investigated the effect of A. distichum leaf extract (ALE) on adipocyte differentiation.Materials/methodsThe cytotoxic effect of ALE was analyzed using cell viability assay. 3T3-L1 preadipocytes were differentiated using induction media in the presence or absence of ALE. Lipid accumulation was confirmed using Oil Red O staining. The mRNA expression of adipogenic markers was measured using RT-PCR, and the protein expressions of mitogen-activated protein kinase (MAPK) and peroxisome proliferator-activated receptor gamma (PPARγ) were measured using western blot. Cell proliferation was measured by calculating the incorporation of Bromodeoxyuridine (BrdU) into DNA.ResultsALE reduced lipid accumulation in differentiated adipocytes, as indicated by Oil Red O staining and triglyceride assays. Treatment with ALE decreased the gene expression of adipogenic markers such as Pparγ, CCAAT/enhancer binding protein alpha (C/ebpα), lipoprotein lipase, adipocyte protein-2, acetyl-CoA carboxylase, and fatty acid synthase. Also, the protein expression of PPARγ was reduced by ALE. Treating the cells with ALE at different time points revealed that the inhibitory effect of ALE on adipogenesis is higher in the early period treatment than in the terminal period. Furthermore, ALE inhibited adipocyte differentiation by reducing the early phase of adipogenesis and mitotic clonal expansion. This was indicated by the lower number of cells in the Synthesis phase of the cell cycle (labeled using BrdU assay) and a decrease in the expression of early adipogenic transcription factors such as C/ebpβ and C/ebpδ. ALE suppressed the phosphorylation of MAPK, confirming that the effect of ALE was through the suppression of early phase of adipogenesis.ConclusionsAltogether, the results of the present study revealed that ALE inhibits lipid accumulation and may be a potential agent for managing obesity.
