Mitosis in Tilia americana endosperm
The endosperm cells of the American basswood Tilia americana are favorable experimental material for investigating the birefringence of living plant spindles and anaphase movement of chromosomes. The behavior of the chromosomes in anaphase and the formation of the phragmoplast are unique. The numerous (3 n equals 123), small chromosomes move in precise, parallel rows until midanaphase when they...
متن کاملThe influence of basswood (Tilia americana) and soil chemistry on soil nitrate concentrations in a northern hardwood forest
In the Arbutus Lake Watershed in the Adirondack Mountains, New York, two nearly adjacent catchments (14 and 15) varied significantly in volume-weighted stream water nitrate (NO3) export (54 and 17 mequiv. L–1, respectively; P < 0.001). The most notable differences between the catchments were that Catchment 14 had significantly higher soil Ca concentrations and patches of basswood (Tilia america...
متن کاملNuclear P Protein in Sieve Elements of Tilia Americana
Tubular and fibrillar forms of P protein (slime) have been reported in sieve elements of a wide range of higher vascular plants . However, all P protein components encountered in previous investigations have been extranuclear in their occurrence . At this time we are reporting on the presence of tubular and fibrillar forms of P protein in both nucleus and cytoplasm of differentiating sieve elem...
متن کاملCeratocystis tiliae sp. nov., a wound pathogen on Tilia americana.
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...
متن کاملPharmacokinetic Study of Biotransformation Products from an Anxiolytic Fraction of Tilia americana.
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...
