The genus Castanea (Fagaceae) is widely distributed in the deciduous forests of the Northern Hemisphere. The striking similarity between the floras of eastern Asia and those of eastern North America and the difference in chestnut blight resistance among species has been of interest to botanists for a century. To infer the biogeographical history of the genus, the phylogeny of Castanea was estim...

We have added 275 AFLP and 24 SSR markers and the 5SrDNA locus to a previously published genetic map based on a hybrid cross between Castunea mollissima and C dentata. The SSR markers, 5SrDNA locus, and one isozyme locus also permitted us to correlate the linkage groups in the published genetic map of C. sativa with those in our C. milkimalC deniata map. Correlating the map of European chestnut...

Palynological spectrum, proximate and fatty acid (FA) composition of eight bee bread samples of different botanical origins were examined and significant variations were observed. The samples were all identified as monofloral, namely Castanea sativa (94.4%), Trifolium spp. (85.6%), Gossypium hirsutum (66.2%), Citrus spp. (61.4%) and Helianthus annuus (45.4%). Each had moisture content between 1...

This work was aimed at evaluating the cardioprotective effects of Castanea sativa Mill. (CSM) bark extract characterized in its phenolic composition by HPLC-DAD-MS analysis. The study was performed using primary cultures of neonatal rat cardiomyocytes to investigate the antioxidant and cytoprotective effects of CSM bark extract and isolated guinea pig left and right atria, left papillary muscle...

A comparative genetic and QTL mapping was performed between Quercus robur L. and Castanea sativa Mill., two major forest tree species belonging to the Fagaceae family. Oak EST-derived markers (STSs) were used to align the 12 linkage groups of the two species. Fifty-one and 45 STSs were mapped in oak and chestnut, respectively. These STSs, added to SSR markers previously mapped in both species, ...

Following the successful operation of a European High Performance Computer For Fusion applications (HPC-FF) in Jülich, Germany, from 2009 to 2013, a new supercomputer dedicated to magnetic fusion research was procured within the Broader Approach agreement between Europe and Japan. The new platform, “Helios”, was installed in the International Fusion Energy Research Centre Computational Simulati...

The European chestnut (Castanea sativa) is threatened by the hemibiotrophic oomycete Phytophthora cinnamomi, causal agent of ink disease. Chestnut species have different susceptibility levels to P. with Asian (C. crenata; C. mollissima) exhibiting highest level resistance. A histological approach was used study responses exhibited susceptible and resistant genotypes characterizing early stages ...

Bu çalışmada, Zonguldak Gökgöl Mağarası yakınlarında Doğu kayını (Fagus orientalis Lipsky), Anadolu kestanesi (Castanea sativa Mill.) ve Adi gürgen (Carpinus betulus L.) türlerinden oluşan karışık meşcerede münferit halde bulunan 4 adet yaşlı Taxus baccata L. bireyinin anıtsal özellikleri incelenmiştir. Tahmini yaşları 915 ila 1180 arasında değişen bu ağaçların Şimdiki Anıtsal Değerleri (ŞAD) 7...

Heat treatment is often used for improve the dimensional stability of wood. In this study, effect of heat treatment on equilibrium moisture content (EMC) of oak (Quercus petraea Lieb.), chestnut (Castanea sativa Mill.), calabrian pine (Pinus brutia Ten.) and black pine (Pinus nigra Arnold.) woods, obtained from Kastamonu Forest Enterprises of Turkey, was examined. Wood specimens were subjected ...

Cold acclimation in woody plants may have special features compared to similar processes in herbaceous plants. Recent studies have shown that circadian clock behavior in the chestnut tree (Castanea sativa) is disrupted by cold temperatures and that the primary oscillator feedback loop is not functional at 4 degrees C or in winter. In these conditions, CsTOC1 and CsLHY genes are constantly expre...
