Terminalia trees are being over-exploited because of their medicinal and economical importance leading to loss of valuable genetic resources. For sustainable utilization and conservation, assessment of genetic diversity therefore becomes imperative. We report a comprehensive first study on estimation and analysis of genetic variation through Amplified fragment length polymorphism (AFLP), inter simple sequence repeat polymorphism (ISSR) and random amplification of polymorphic DNA (RAPD) across three species of Terminalia.

Five Gram-negative, rod-shaped, non-spore-forming bacteria were isolated from galls on different plant species in Hungary: strain 39/7(T) from Prunus cerasifera Myrobalan, strain 0 from grapevine var. Ezerjó, strain 7/1 from raspberry var. Findus and in Poland, strain C3.4.1 from Colt rootstock (Prunus avium × Prunus pseudocerasus) and strain CP17.2.2 from Prunus avium. Only one of these isolates, strain 0, is able to cause crown gall on different plant species.

In this study, a tropical endophytic fungus, Alternaria alternata Tche-153 was isolated from a Thai medicinal plant Terminalia chebula Rezt. The ethyl acetate extract prepared from the fermentation broth exhibited significant ketoconazole-synergistic activity against Candida albicans. Bioassay-directed fractionation of the ethyl acetate extract led to the isolation of altenusin (1), isoochracinic acid (2), and altenuic acid (3) together with 2,5-dimethyl-7-hydroxychromone (4).

Terminalia, a large genus of Combretaceae, is distributed in Tropical Asia, Africa, and America. Some Terminalia plants are used in folk medicine because they possess powerful medicinal properties. Dried fruits of Terminalia bellirica and Terminalia chebula are used as the main ingredient in Triphala, a famous polyherbal formulation in Ayurvedic medicine and Thai folk medicine, because of their laxative, detoxifying, and rejuvenating effects. To clarify the phylogenetic relationships of medicinal Terminalia species (T. bellirica, T. chebula, and T.

Strains of Caenorhabditis elegans mutant for clk-1 exhibit a 20-40% increase in mean lifespan. clk-1 encodes a mitochondrial protein thought to be either an enzyme or regulatory molecule acting within the ubiquinone biosynthesis pathway. Here CLK-1 is shown to be related to the ubiquinol oxidase, alternative oxidase, and belong to the functionally diverse di-iron-carboxylate protein family which includes bacterioferritin and methane mono-oxygenase.

Ticks are obligate hematophagous ectoparasites with a life cycle characterized by a period of starvation; many ticks spend more than 95% of their life off the host. Autophagy, which is the process of bulk cytoplasmic degradation in eukaryotic cells, is induced by starvation and is essential for extension of the lifespan. Therefore, we hypothesized that autophagy also occurs in ticks; however, there has been no report on autophagy-related (ATG) genes in ticks.

Studying the biological functions of the aryl hydrocarbon receptor (AhR) other than its function in xenobiotic drug metabolism may answer the questions as to why AhR orthologues have long been conserved phylogenically widely in the animal kingdom, and why homologues have diverged from nonvertebrate species such as nematodes and drosophila to all the vertebrate species.

Human senescence patterns-late onset of mortality increase, slow mortality acceleration, and exceptional longevity-are often described as unique in the animal world.

The SLC16 gene family has fourteen members. Four (SLC16A1, SLC16A3, SLC16A7, and SLC16A8) encode monocarboxylate transporters (MCT1, MCT4, MCT2, and MCT3, respectively) catalysing the proton-linked transport of monocarboxylates such as l-lactate, pyruvate and ketone bodies across the plasma membrane. SLC16A2 encodes a high affinity thyroid hormone transporter (MCT8) and SLC16A10 an aromatic amino acid transporter (TAT1). The substrates and roles of the remaining eight members are unknown.

Comparative studies of aging are often difficult to interpret because of the different factors that tend to correlate with longevity. We used the AnAge database to study these factors, particularly metabolism and developmental schedules, previously associated with longevity in vertebrate species. Our results show that, after correcting for body mass and phylogeny, basal metabolic rate does not correlate with longevity in eutherians or birds, although it negatively correlates with marsupial longevity and time to maturity.
