Chloroplast Genomes of and : Molecular Structure, Phylogenetic, and Comparative Analyses for Wild Plant Conservation.

The chloroplast genome plays a crucial role in elucidating genetic diversity and phylogenetic relationships. L. (grapevine) is an economically important species, prompting exploration of wild genetic resources to enhance stress resilience.

Phylogenomics and morphological evolution of the mega-diverse genus Artemisia (Asteraceae: Anthemideae): implications for its circumscription and infrageneric taxonomy.

Background And Aims: Artemisia is a mega-diverse genus consisting of ~400 species. Despite its medicinal importance and ecological significance, a well-resolved phylogeny for global Artemisia, a natural generic delimitation and infrageneric taxonomy remain missing, owing to the obstructions from limited taxon sampling and insufficient information on DNA markers. Its morphological characters, such as capitulum, life form and leaf, show marked variations and are widely used in its infrageneric taxonomy.

The complete plastid genome sequence of (Ericales: Ericaceae), a deciduous broad-leaved shrub endemic to East Asia.

We here sequenced the complete plastid genome (plastome) of (Ericaceae), a deciduous broad-leaved shrub endemic to East Asia. This species has considerable practical economic value. The plastome of is assembled as a single contig (187,213 bp).

Antioxidant activity in essential oils of Cnidium officinale makino and Ligusticum chuanxiong Hort and their inhibitory effects on DNA damage and apoptosis induced by ultraviolet B in mammalian cell.

Background: Owing to their high volatile aroma, the dried rhizomes of Cnidium officinale (C. officinale) and Ligusticum chuanxiong (L. chuanxiong) are used as herbal drugs to treat blood pressure depressant, a deficiency disease of antivitamin, inhibition of small intestine sympathetic nerve and as cosmetics for skin care.

Protective effect of the extracts from Cnidium officinale against oxidative damage induced by hydrogen peroxide via antioxidant effect.

The dried rhizomes of Cnidium officinale are used as herbal drugs in the treatment of pain, inflammation, menstrual disturbance and antivitamin deficiency disease, and also act as a blood pressure depressant. In addition, there are several reports suggesting that they have pharmacological properties to tumor metastasis and angiogenesis, and that they act as an inhibitor of high glucose-induced proliferation of glomerular mesangial cells. However, little has been known about the functional role of the extracts from C.

Phylogenetic, morphological, and chemotaxonomic incongruence in the North American endemic genus Echinacea.

The study of recently formed species is important because it can help us to better understand organismal divergence and the speciation process. However, these species often present difficult challenges in the field of molecular phylogenetics because the processes that drive molecular divergence can lag behind phenotypic divergence. In the current study we show that species of the recently diverged North American endemic genus of purple coneflower, Echinacea, have low levels of molecular divergence.

Cancer-preventive peptide lunasin from Solanum nigrum L. inhibits acetylation of core histones H3 and H4 and phosphorylation of retinoblastoma protein (Rb).

Lunasin, a unique 43 amino acid, 4.8 kDa cancer-chemopreventive peptide initially reported in soybean and now found in barley and wheat, has been shown to be cancer-chemopreventive in mammalian cells and in a skin cancer mouse model against oncogenes and chemical carcinogens. To identify bioactive components in traditional herbal medicines and in search for new sources of lunasin, we report here the properties of lunasin from Solanum nigrum L.

The cancer preventive peptide lunasin from wheat inhibits core histone acetylation.

Lunasin is a unique 43-amino acid cancer preventive peptide initially reported in soybean and barley and has been shown to be chemopreventive in mammalian cells and in a skin cancer mouse model against oncogenes and chemical carcinogens. We report here the core histone H3- and H-acetylation inhibitory properties of lunasin from wheat, a new source of the peptide and from the livers of rats fed with lunasin-enriched wheat (LEW) to measure bioavailability. A non-radioactive histone acetyl transferase assay was used to measure inhibition of core histone acetylation.
