Background: Diabetes mellitus increases the risk of central nervous system (CNS) disorders such as stroke, seizures, dementia, and cognitive impairment. Berberine, a natural isoquinolne alkaloid, is reported to exhibit beneficial effect in various neurodegenerative and neuropsychiatric disorders. Moreover astrocytes are proving critical for normal CNS function, and alterations in their activity...

Interspecific crosses between the more than 520 Passiflora species may or not be compatible. The sequences ITS, matK, psbA-trnH, rbcL and trnL-F were used to confirm identity estimate genetic distances among 48 accessions of a germplasm bank. Twenty for within distinct subgenera. phylogenetic resolution based on ITS data was superior that any single chloroplast marker, recommending it as DNA ba...

The phylogenetic relationships among 23 species of the tribe Tigridieae (lridaceae) were inferred using morphological data and nucleotide sequences from nuclear ITS and three intergenic spacers of the cpDNA: psbA-trnH, trnT-trnL, and trnL-trnE Although all data sets supported a monophyletic Mexican-Guatemalan Tigridiinae including two taxa usually placed in Cipurinae ( Cardiostigma longispatha ...

Background Past climate changes have severely influenced the current distribution of species and their genetic diversity. Phylogeography is the study of the principles and processes governing the geographic distributions of genealogical lineages [1]. South America has the world’s largest area of swamps, floodplains and wetlands in general [2]. Brazil’s major wetlands cover 2% of the country’s h...

The genus Onosma is a homogeneous taxon with high morphological variation and due to the similarities among taxa, there are many problems in their identification. Hence, systematically taxonomically, it considered difficult genus. In present study, we included large number of species throughout distribution range. Using nuclear (ITS) two plastids (rpl32-trnL(UAG) trnH-psbA) markers, analyzed ev...

This study proposes the use of genetic analysis as a complementary method for species identification in genus Pinus, particularly cases where anatomical is challenging. Pinus were grouped based on similarities, and efficacy using ycf1b, which most variable identification, rbcL, suggested DNA barcode land plants, was evaluated within each group. Sequences obtained from National Center Biotechnol...
