aucuparia is an important slow growth forest tree with medicinal, industrial and ornamental uses which is applied for reforestation in high altitude of mountain lands. this species has been endangered at northern forests of iran; therefore micropropagation of adult trees by bud culture may help to reforestation. the best sterilizing treatment was the buds washing with hgcl2% 0.1 solution for 7 ...

eucalyptus globulus is an important rapid-growing trees in eucalypts that applied for agroforestry and tree improvement programs. it has been used as a source of pulp in paper industry, essential oil and honey production. asexual propagation with conventional methods such as cutting and graft wasnot possible or obtained success was very low, because of hard proliferation of adventitious roots. ...

In this research, some independent experiments were carried out for investigating the effects of microspore developmental stage, bud pretreatments (cold, heat and Ca), and embryo induction medium on anther culture of some strawberry cultivars. The results showed that the percentages of responsive and embryogenic anthers in cultivar Paros in liquid medium were influenced not only by different de...

Ectoderm inhibits the formation of cartilage by chick wing bud mesenchyme in micromass culture. This suggests that the pattern of cartilage formation in the limb bud may result from a restriction of cartilage cell differentiation to the limb bud core as cells leave the progress zone. We have used in situ hybridization to investigate whether ectodermal inhibition in micromass culture occurs at t...

The homeobox gene Emx2 is a mouse homologue of a Drosophila head gap gene empty spiracles (ems) and is essential for the development of dorsal telencephalon (Yoshida, M., Suda, Y., Matsuo, I., Miyamoto, N., Takeda, N., Kuratani, S. and Aizawa, S. (1997) Development 124, 101-111). At the same time, Emx2 is expressed in the epithelial components of the developing urogenital system and, in Emx2 mu...

In the developing chick leg bud, massive programmed cell death occurs in the interdigital region. Previously, we reported the inhibition of cell death by separation of the interdigital region from neighboring digit cartilage. In this study, we examined the relationship between cell death and cartilaginous tissue in vitro. First, cell fate was observed with DiI that was used to examine cell move...

A reliable method is described for rapid proliferation of axillary shoots from nodal segment of mature field-grown aromatic and medicinal plant Vitex negundo through in vitro culture. Of different concentrations of N6-benzyladenine (BA) evaluated as supplements to Murahige and Skoog (MS) medium, BA at 1mg/l was effective in enhancing bud break and shoot regeneration. Response of explants was al...
