Background: Pine bark (Pinus spp.) extract is rich in bioflavonoids, predominantly proanthocyanidins, which are antioxidants. Commercially-available extract supplements are marketed for preventing or treating various chronic conditions

Foliar and root P concentrations, net H(2)PO(4) (-) (P(i)) uptake rates, and root surface acid phosphatase (APase) rates were assessed in pitch pine (Pinus rigida Mill.) seedlings inoculated with the ectomycorrhizal fungi Laccaria bicolor (Maire) Pat., Paxillus involutus (Batsch.) Fr., or Pisolithus

Pollen grains and pollen tubes of Pinus roxburghii were subjected to histochemical technique with a view to determining the distributional pattern of reserve substances (ascorbic acid, proteins starch, polysaccharides, nucleic acids) and some enzymes (acid phosphatase, glucose-6-phosphatase,

In this study, Pinus koraiensis seedlings were grown under elevated CO2 (500 and 700 micromol x mol(-1)), and the hydrolase activities in 0 - 10 cm soil layer were determined. The results showed that compared with those under ambient condition, the activities of soil protease, urease, amylase and

The objectives of the present study were to characterize the chemical composition, antioxidant activity and hepatoprotective effect of the polysaccharides from Taishan Pinus massoniana pollen (TPPPS). HPLC analysis showed that TPPPS was an acidic heteropolysaccharide with glucose and arabinose as

To explore the potential of ectomycorrhizal (ECM) Pinus sylvestris (P. sylvestris) utilizing in the phytoremediation of a combined heavy metal contaminated tailings pond, Pisolithus sp.1(P1)-. Pisolithus sp.2 (P2)-. Cenococcum geophilum (Cg)-. Laccaria sp. (L1)- ECM, and non-ectomycorrhizal (NM) P.

We evaluated responses of hydrolase and oxidase activities in a subtropical Pinus elliottii plantation through a nitrogen (N) addition field experiment (dosage level: 0, 40, 120 kg N·hm-2·a-1). The results showed that N additions significantly decreased the carbon, nitrogen and phosphorus related

A novel cellulolytic bacterium, strain S23(T), was isolated from the rhizosphere of the pine trees in Daejeon, Republic of Korea. This isolate was Gram-positive, strictly aerobic, rod-shaped, catalase-negative, oxidase-positive, motile by means of peritrichous flagella, and tested positive for

Reforestation in China is important for reversing anthropogenic activities that degrade the environment. Pinus tabulaeformis is desired for these activities, but survival and growth of seedlings can be hampered by lack of ectomycorrhizae. When outplanted in association with Ostryopsis davidiana

The hepatoprotective activity of Pinus massoniana bark extract (PMBE) against hydrogen peroxide (H2O2)-induced damage in normal human liver L-02 cells and carbon tetrachloride (CCl4)-induced acute hepatotoxicity in mice was investigated. The L-02 cells were pre-treated with PMBE for 24 hours prior

The present study attempts to establish a relationship between ethnopharmacological claims and bioactive constituents present in Pinus roxburghii against all possible targets for diabetes through molecular docking and to develop a pharmacophore model for the active target. The process of molecular

The association of ectomycorrhizal fungi with tree roots enhances the acquisition of phosphorus (P) from the soil. In addition to increasing the uptake of H(2)PO(4) (-) (P(i)), mycorrhizal fungi may increase the spectrum of P sources utilized by tree roots by mediating the dissolution of insoluble

Young seedlings of maritime pine (Pinus pinaster Soland in Aït.) were grown in rhizoboxes using intact spodosol soil samples from the southwest of France, in Landes of Gascogne, presenting a large variation of phosphorus (P) availability. Soils were collected from a 93-year-old unfertilized stand
