1. Small stems with one large leaf in the middle produce shoots and roots chiefly at the expense of material sent into the stem by the leaf. Since the sap of the leaf can cause the formation of roots and shoots in the same notch of the leaf, it is difficult to assume that the polar character of the regeneration in the stem is due to a chemical difference in the ascending and descending sap sent...

Neurospheres were obtained by culturing hippocampal cells from transgenic rat fetuses (E16) expressing green fluorescent protein (GFP). The neurosphere cells were injected into the cerebrospinal fluid (CSF) through the 4th ventricle of young rats (4 weeks old) that had been given a contusion injury at T8-9 of the spinal cord. The injected neural stem cells were transported through the CSF to th...

anise hyssop is a prennial herb belonging to the lamiaceae family. essential oil of this plant is used in food, pharmaceuticals, cosmetics industries as well as flavoring liqueurs. since water stress affects the growth, productivity, as well influences the active principles governing medicinal plants, in this research the effect of different water deficit stresses on such morphological traits a...

This paper describes experiments on Cl transport into the roots, stem and leaves of bean plants, the roots of which have been exposed to lipids in the root solution. Monoand digalactose diglyceride strongly increased Cl transport into all plant parts, probably by transport of the glycolipids further into the plant. Phosphatidyl choline increased Cl absorption by the roots, but transport into th...

introduction: potential almond rootstock and thus main genetic sources for the breeding of its new rootstocks are almond itself, peach and plum, and these species cross-breeds almond is a source of resistance to limestone and to drought because of its roots, which reach deep layers of soil; it is also more resistant than peach to na and bo. asexual or vegetative propagation is a hereditable cha...

The role of roots in the enhancement of cytokinin content and leaf growth of Phaseolus vulgaris plants after decapitation and partial defoliation was investigated. Partial excision of the roots of plants which were decapitated above the primary leaf node resulted in a reduction of leaf growth and soluble proteins accumulation in the primary leaves. Roots excision was done at time of decapitatio...

Cassava (Manihot esculenta) is valued mainly for high content starch in its roots. Our understanding of mechanisms promoting high starch accumulation in the roots is, however, still very limited. Two field-grown cassava cultivars, Huanan 124(H124) with low root starch and Fuxuan 01(F01) with high root starch, were characterised comparatively at four main growth stages. Changes in key sugars in ...

Background: Periodontal ligament stem cells (PDLSCs) are considered as a type of mesenchymal stem cell that is beneficial target for numerous clinical applications in periodontal tissue regeneration therapy. Materials and Methods: This study examined the effects of dexamethasone (Dex) on human PDLSCs in vitro. PDLSCs obtained from the roots of patient’s teeth were cultured with Dex (0....

The impact of hiking in forested areas is one the main factors affecting condition tree growth along trails. Trampling causes common exposure roots and quantification human on root radial wood anatomy requires careful assessment. To accurately identify changes Pinus sylvestris roots, we conducted a stepwise cross-dating using trampled from trail reference roots. Such approach was previously not...
