The natural biology of Saccharomyces cerevisiae, the best known unicellular model eukaryote, remains poorly documented and understood although recent progress has started to change this situation. Studies carried out recently in the Northern Hemisphere revealed the existence of wild populations associated with oak trees in North America, Asia, and in the Mediterranean region. However, in spite ...

The impact of both the uplift of the Qinghai-Tibetan Plateau (QTP) and the separation of the Taiwan and Hainan Islands on the evolution of the fauna and flora in adjacent regions has been a topic of considerable interest. Mollitrichosiphum is a polyphagous insect group with a wide range of host plants (14 families) and distributions restricted to Southeast Asia. Based on the mitochondrial Cytoc...

Dominant groups and rare often coexist in forests. Dominate plant families generally have more species diversity occupy most of the biomass. However, their effects on community construction maintenance remain to be studied. This study aims investigate this question by using two dominant a Chinese subtropical forest (Lauraceae Fagaceae). In study, 22 dynamic plots were established distribution a...

Morphological variations of acorn among and within the groups of Quercus species were studied. A total of 617 acorns belonging to 14 species representing all 3 sections of Quercus L. (Fagaceae) in Turkey were examined in this study. Specimens were collected from 47 different populations over both Anatolian and Thrace part of Turkey. Principal component analysis was used to analyze the morpholog...

Abstract The Late Oligocene to Early Miocene flora of the Ban Pa Kha Subbasin (Li Basin, northern Thailand) provides a record montane dry tropical oak-pine forests. rich ensemble Fagaceae typical these forests might have existed in wider region Southeast Asia since Eocene times and various fossil plant assemblages represented both lowland (Fagaceae, Dipterocarpaceae) upland Pinaceae) These find...

The biodiversity of mycorrhizal and wood-inhabiting macrofungi (basidiomycetes) is declining, many species are threatened in forests. Based on data from a 30-year fruiting body survey 1988 to 2017 the region city Jena (100,000 inhabitants, 4500 ha forest), Germany, we evaluated role urban environment with variation ownership, property size, associated management, high diversity woody for presen...

In vitro antioxidant activities of three sweet dihydrochalcone glucosides from the leaves of Lithocarpus pachyphyllus (Kurz) Rehd. (Fagaceae), trilobatin 2"-acetate (1), phloridzin (2) and trilobatin (3), were investigated. The IC50 (50% inhibitory concentration) values for compounds 1-3 of lipid peroxidation in rat liver homogenate were 261, 28, 88 microM, respectively. Compounds 1-3 increased...
