1. VITRO OF Melanoxylon brauna SCHOTT. MORPHOGENESIS: RESPONSIVENESS OF EXPLANTS TO PERMANENT AND TEMPORARY IMMERSION GROWTH REGULATORS
ABSTRACT Melanoxylon brauna is propagated by seeds, however, low yield, pest attack and short viability are problems in seedling production. In vitro cultivation is an alternative for large-scale seedling production, but studies with this species are scarce. The aim of the work was to analyze the in vitro morphogenesis of braúna. Explants after induction of

2. In Vitro Organogenesis from Root Explants of Passiflora miniata Mast., an Amazonian Species with Ornamental Potential
ABSTRACT The present study reports a shoot organogenesis-based system for in vitro regeneration of Passiflora miniata, an Amazonia passion fruit species. Root segments were cultured in Murashige and Skoog (MS) medium supplemented with different concentrations (range 2-9 µM) of 6-benzyladenine (BA); thidiazuron (TDZ) or kinetin (KIN). Plant growth regulators

3. Micropropagation of Physalis peruviana L.
RESUMO Physalis peruviana L. (Solanaceae) é uma frutífera herbácea, que vem se consolidando no mercado em virtude de suas potencialidades nutricionais e medicinais. As limitações à sua produção são o ciclo reprodutivo curto, o acometimento dos frutos por pragas e a carência de estudos, o que justifica a busca de estratégias para a sua propagação

4. Development of the endocrine pancreas and novel strategies for β-cell mass restoration and diabetes therapy
Diabetes mellitus represents a serious public health problem owing to its global prevalence in the last decade. The causes of this metabolic disease include dysfunction and/or insufficient number of β cells. Existing diabetes mellitus treatments do not reverse or control the disease. Therefore, β-cell mass restoration might be a promising treatment. Severa

5. Progress in micropropagation of Passifloraspp. to produce medicinal plants: a mini-review
Micropropagation of Passiflora species and its hybrids may play an important role in the production of healthy and disease-free plants which can be a source of medicinal herbal products, nutritional fruits and ornamental flowers. The rapid multiplication of elite plants to obtain pharmacognostic material, containing valuable flavonoid C-glycosides, is possib

6. Anatomical studies of in vitro organogenesis induced in leaf-derived explants of passionfruit.
With the aim os studying the organogenesis in vitro in Passiflora edulis Sims f. flavicarpa Deg., the passionfruit, leaf-derived explants were cultured on media containing NAA or BAP and incubated either in continuous darkness or in light. The histological events leading to de novo organ formation were evaluated. Darkness induces rhizogenesis in the presence

7. Agrobacterium-mediated genetic transformation of 'Hamlin' sweet orange.
The development and optimization of efficient transformation protocols is essential in new citrus breeding programs, not only for rootstock, but also for scion improvement. Transgenic 'Hamlin' sweet orange (Citrus sinensis (L.) Osbeck) plants were obtained by Agrobacterium tumefaciens-mediated transformation of epicotyl segments collected from seedlings germ

8. Padronização de metodologias de regeneração, via embriogênese somática e organogênese, e de aclimatização de soja (Glycine max (L.) Merrill) / Methodology standardization for regeneration via somatic embryogenesis and organogenesis and for acclimatization of soybean (Glycine max (L.) Merrill)
Different methodologies for in vitro regeneration have already been developed for several soybean cultivars. However, this species has proven to be recalcitrant to tissue culture and its in vitro morphogenetic response has been considered genotype dependent. Taking into account the need to develop reliable protocols for regeneration and acclimatization in so

10. RegeneraÃÃo "in vitro", estudos histolÃgicos e transformaÃÃo genÃtica da momoneira (Ricinus communis) / "In vitro" regeneration, histologycal studies and genetic transformation of castor-bean (Ricinus communis)
Castor bean (Ricinus communis) is an oilseed crop with considerable economic value because of the composition of its oil seed. However, there are some constraints in your use for human and animal food because of the presence of toxic and allergenic proteins. This problem could be solved or reduced through genetic engineering. However, this crop is recalcitra
