Hop (Humulus lupulus L.) is cultivated for the female fl owers, or “cones,” which traditionally have been used as a bittering and fl avoring agent in beer. Hop breeding historically relied on relatively simple selection techniques within established breeding lines. Supplementing current breeding material with new genetic sources would enhance a hop breeder’s ability to select for new traits. Th...

Holarrhena pubescens Wall. ex G. Don (H. pubescens), belonging to the Apocynaceae family, is distributed in deciduous forests of tropical Himalayas. H. an important traditional medicinal plant, especially its seeds and barks. Therefore, we assessed antioxidant capacity extracts Lipopolysaccharide (LPS)-induced dendritic cells (DCs) for sepsis treatment. Our results indicated that with different...

BACKGROUND Petalostigma pubescens and Petalostigma triloculare were common components of pharmacopeia's of multiple Australian Aboriginal tribal groupings which traditionally inhabited the areas in which they grow. Among these groups, they had a myriad of medicinal uses in treating a wide variety of bacterial, fungal and viral infections. This study was undertaken to test P. pubescens and P. tr...

Inhibition of the net photosynthetic CO 2 assimilation rate ( P n ) by high temperature was examined in oak ( Quercus pubescens L.) leaves grown under natural conditions. Combined measurements of gas exchange and chlorophyll (Chl) a fluorescence were employed to differentiate between inhibition originating from heat effects on components of the thylakoid membranes and that resulting from effect...

Millions of hectares of tropical forests have been converted to agricultural land and abandoned, so it is important that we understand the process of forest recovery and comprehend how pathways are modified by different types of disturbance in different geographic regions. In a 4-year case study, we quantified the pattern of forest recovery following clearing and 3 years of cultivation of a moi...

Hamilton and Brown suggested that bright autumn coloration in trees is an energetically expensive and therefore honest (handicap) signal of defensive commitment against insects. If this is so, one should expect that the intensity of the proposed signal should depend strongly on tree health. However, to the best of our knowledge, the link between vigour and autumn colour has never been tested. W...
