Effects of 6 substances of 29 specifically expressed in the pre-simbiotic phase of Tuber borchii − Tilia americana interaction and root extracts obtained in water and ethanol were tested on T. borchii mycelium. Root extracts increased hyphal branching; this is in agree with data obtained using only endo-mycorhhizal fungi. The tested substances showed various effects on morphology and features o...

Species in the North American clade (NAC) of the Ceratocystis fimbriata complex are mostly weak pathogens that infect native tree hosts through fresh wounds. Isolations from discolored tissue of wounded Tilia americana (basswood) in Iowa and Nebraska yielded a Ceratocystis species that was similar to but distinct from isolates of C. variospora from other hosts. Sequences of 28S rDNA showed that...

Three pure cultures of Xylaria polymorpha were isolated from fruiting bodies at yearly intervals over two years and maintained on 2% malt agar plates at room temperature. Immediately after isolation of the third culture, the cultures were inoculated onto sugar maple (Acer saccharum), aspen (Populus tremuloides), birch (Betula alleghaniensis), and basswood (Tilia americana) 14 mm cubes and incub...

We quantified the damage caused by a major ice storm to individual trees in two 1-ha permanent plots located at Mont St. Hilaire in southwestern Québec, Canada. The storm, which occurred in January 1998, is the worst on record in eastern North America; glaze ice on the order of 80-100 mm accumulated at our study site. All but 3% of the trees (DBH > or = 10 cm) lost at least some crown branches,...

Tilia is an ecologically and economically important genus in the family Malvaceae. However, there is no complete plastid genome of Tilia sequenced to date, and the taxonomy of Tilia is difficult owing to frequent hybridization and polyploidization. A well-supported interspecific relationships of this genus is not available due to limited informative sites from the commonly used molecular marker...

An anxiolytic fraction of Tilia americana standardized in tiliroside, rutin, quercitrin, quercetin glucoside, and kaempferol was obtained. After oral administration of the fraction, the above-mentioned flavonoids were not detected in plasma over 24 h. However, meta and para hydroxyphenylacetic acid and dihydroxyphenylacetic acid (m-HPAA, p-HPAA and DOPAC) were monitored. These are the biotransf...
