the present work developed an efficient plant regeneration and propagation system via direct organogenesis for morinda officinalis how., a valuable endangered medicinal plant. the effects of explant types on shoot induction, plant growth regulators on shoot proliferationand elongation and the subsequent rooting ability of shoots were examined. among the various types of explant, direct shoot pr...

The gesneriaceous perennial plant, Lysionotus serratus, has been used in traditional Chinese medicine. It also has a great development potential as an ornamental plant with its attractive foliage and beautiful flowers. An efficient propagation and regeneration system via direct shoot organogenesis from leaf explant was established in this study. High active cytokinin (6-benzyladenine (BA) or th...

Wild plant species are of great interest as a source pharmacologically valuable compounds but number them endemic and/or endangered ones. Modern biotechnology can provide reliable methods for their utilization without disturbing natural populations. In vitro culture Rhodiola being intensively developed to include into various biotechnological programmes. Aim. Development protocol direct rosea L...

Tissue culture provides a useful system to investigate how plant hormones are involved in this process. Auxin and cytokinin are widely used in plant regeneration. Gibberellin is also an important plant hormone in regulating plant growth and development. It is interesting to know the effects of gibberellin and its signalling pathway on plant regeneration. In this report Arabidopsis thaliana land...

Agrobacterium-mediated transformation of indica rice has been established in only a limited number of cultivars because the regeneration of plants from transformed embryogenic calli is highly cultivar-specific. Establishment of a highly efficient plant regeneration system from shoot apex explants applicable to many cultivars of indica rice will accelerate the application of transformation techn...

Dwarf hygro (Hygrophila polysperma) is an ornamental aquatic plant that changes its leaf colours to pinkish in high light. It is listed as a medicinal plant in medicinal plant lists of Indian states of West Bengal and Karnataka. It is also used as a screening tool for toxicities and a bioindicator to detect and control algae. The study reported in vitro adventitious shoot regeneration from leaf...

De novo shoot regeneration is widely used in fundamental studies and agricultural applications. Actin microfilaments are involved in many aspects of plant cell division, cell morphogenesis and cell signal transduction. However, the function of actin microfilaments during de novo shoot regeneration is poorly understood. Here, we investigated the organization of actin microfilaments during this p...

Three basal plant tissue culture media, namely, N6, MS, and modified Y3, were compared to optimize micropropagation protocol for E. guineensis. Full strength media were used separately to regenerate plantlets directly using immature zygotic embryos (IZEs), and through somatic embryogenesis of calli obtained from IZEs. The plantlets regenerated by direct regeneration on three media were examined...

Punicagranatum cv. Malassaveh is one of the most desirable commercial cultivars in Iran. In thisstudy some experiments were conducted to introduce the best hormonal treatments for directadventitious shoot regeneration from mentioned cultivar via cotyledonary explants. For thispurpose, both liquid and agarMurashige and Skoog (1962) (MS) medium supplemented with BAat 2, 4.5, 9, 13 μM alone and in...
