1. Rhizobium rhizogenes-mediated transformation of Rhodiola rosea leaf explants
ABSTRACT Rhodiola rosea L. is an endangered medicinal plant distributed in mountains and in high latitude regions. For its conservation, sustainable methods for the obtaining of its bioactive compounds must be developed. This work hypothesized that leaf, stem and rhizome explants of R. rosea from different geographical origins respond differently to inoculat

3. Comparison of in vitro callus-cultures from transgenic maize AG-5011YG (MON810) and conventional near-isogenic maize AG-5011
Abstract MON810 is a genetically-modified (GM) maize (Zea mays) event commonly employed in insect-resistant GM maize hybrids. GM events obtained by biolistic transformation methods, such as MON810, are generated by insertion of a recombinant gene expression cassette in a random locus of the plant genome, and this process may cause emergent properties besides

4. Somatic embryos from Phalaenopsis classic Spotted Pink (Orchidaceae) protocorms
RESUMO: O presente estudo buscou induzir a formação de embriões somáticos em protocormos do híbrido Phalaenopsis Classic Spotted Pink em dois estádios de maturação fisiológica aos 80 e 120 dias após a inoculação das sementes (DAIS). Os protocormos foram inoculados em meio ½ MS suplementado com 0,1 mg L-1 de ANA e 3 mg L-1 de TDZ. Aos 15 dias de

5. Fulminant hepatic failure caused by herbal supplies
The consumption of botanicals for therapeutic purposes has increased significantly in recent years. Drug-induced liver disease (DILI) is a frequent cause of acute liver injury, around 50% in the United States, and about 1% is secondary to the use of phytotherapeuticals and herbal supplies. Ruellia bahiensis, a plant species of the Acanthaceae family, is a tr

6. Micropropagation of Cyrtopodium paludicolum (Orchidaceae) from root tip explants
Abstract An efficient protocol for in vitro plant propagation of Cyrtopodium paludicolum has been developed using root tips dissected from well-developed seedlings. Root tips were cultured on Knudson medium supplemented with α-naphthaleneacetic acid (NAA), and/or thidiazuron (TDZ). TDZ did not induce protocorm-like bodies (PLBs) in the NAA absence, indicati

7. Tissue culture efficiency of wheat species with different genomic formulas
Abstract Ancient wheats are increasingly considered as valuable resources for genes of interest which could be analyzed and introduced into cultivated varieties by genetic engineering technologies. The first stage of biotechnological crop improvement consists of successful in vitro plant regeneration. Twelve wheat germplasms with different genomic formulas (

8. Recurrent Somatic Embryogenesis and Plantlet Regeneration in Psidium guajava L.
A simple and efficient protocol for recurrent somatic embryogenesis and plant regeneration is one of the prerequisites for genetic improvement of guava. An efficient reproducible regeneration somatic embryogenesis protocol was developed in four genotypes of Psidium guajava L. using immature zygotic embryo as starter explant. Somatic embryogenesis induction w

9. Comparative Microbicidal Efficacy of Fractionated Extracts from In Vitro and In Vivo Raised Cells of Tinosporacordifolia Against MDR Pathogens
The present study was conducted to explore the hidden potential of natural products synthesized in the medicinal plant Tinosporacordifolia. This plantis prioritized by National Medicinal Plant Board, New Delhi. Leaf and inter nodal segments were inoculated on MS Medium fortified with IBA (1.0 mg/L) produced callus after four weeks. The calli were brown due t

10. Somatic embryogenesis and plant regeneration in Wedelia calendulacea Less. an endangered medicinal plant
In this work, plant regeneration via somatic embryogenesis was achieved from leaf and internode derived callus of Wedelia calendulacea, an endangered medicinal plant. Primary callus was induced by culturing leaf disc and internode explant on Murashige and Skoog medium supplemented with 2.0 mg L-1 of 2,4-D under light condition. Transfer of embryogenic callus

11. In vitro multiplication of 'Flordaguard' rootstock: cytokinin source and concentration effects, explants orientation and period of permanence in the culture medium
This work aimed at studying the effects of different sources and cytokinin concentrations, as well as explants orientation and time of their permanence in shoots induction medium to obtain high multiplication rate. Four experiments were carried out to evaluate the sprout percentage mean, shoots number per explant, elongated shoots percentage and shoots lengt

12. Transformação de plantas.
ABSTRACT: During centuries mankind plants to obtain cultivars with superior characteristics. However, conventional methods of plant breeding present limitations. The development of transformation methods created possibilities of great progresses in plant breeding because it offers the opportunity to introduce exogenous genes into superior cultivars to obtain
