1. EVALUATING THE ACCUMULATION TREND OF L-DOPA IN DARK-GERMINATED SEEDS AND SUSPENSION CULTURES OF Phaseolus vulgaris L. BY AN EFFICIENT UV-SPECTROPHOTOMETRIC METHOD
Seed germination and plant cell cultures provide an alternative mean for producing secondary metabolites. The present study is an attempt to evaluate the effect of seed dark germination and some elicitors and precursors on the production of L-DOPA in Phaseolus vulgaris L. Callus cultured on Murashige and Skoog medium supplemented with various concentrations

2. Ultrastructure of Zika virus particles in cell cultures
Zika virus (ZIKV) has infected thousands of Brazilian people and spread to other American countries since 2015. The introduction of ZIKV brought a strong impact to public health in Brazil. It is of utmost importance to identify a susceptible cell line that will enable the isolation and identification of the virus from patient samples, viral mass production,

3. Production of Lentiviral Vectors Encoding Recombinant Factor VIII Expression in Serum-Free Suspension Cultures
ABSTRACT Lentiviral vector-mediated gene transfer offers several advantages over other gene delivery vectors when considering gene and cell therapy applications. However, using these therapies in clinical applications involves large-scale vector production in an efficient and cost-effective manner. Here we describe a high yield production of a lentivirus enc

4. Evaluation of limonoid production in suspension cell culture of Citrus sinensis
ABSTRACTThe use of cell and plant tissue culture techniques to produce economically important active metabolites has been growing. Among these substances are total limonoid aglycones, which are produced by "pera" orange (Citrus sinensis (L.) Osbeck, Rutaceae) and have received considerable attention because of their anticancer actions. The main objective of

6. Produção de carotenoides em culturas in vitro de Cleome rosea Vahl ex DC (Capparaceae) e avaliação de sua toxicidade e potencial antioxidante / Carotenoid production in vitro cultures of Cleome rosea Vahl ex DC (Capparaceae) and evaluation of toxicity and antioxidant potential.
The production and optimization of plants secondary metabolites with medicinal value have been achieved by using plant tissue culture techniques, which have showed great relevance when considering the conservation status of a species or their occurrence in degraded environments. The present study assessed the production of carotenoids in callus and cell susp

7. Sucrose metabolizing enzymes in cell suspension cultures of Bauhinia forficata, Curcuma zedoaria and Phaseolus vulgaris.
The objective of this work was to study the activity of sucrose metabolizing enzymes in extracts of cell suspension cultures of Bauhinia forficata Link, Curcuma zedoaria Roscoe and Phaseolus vulgaris L. Invertase pathway was identified in the three studied species. Sucrose synthase pathway was also responsible for sucrose metabolism in Curcuma zedoaria and P

8. Cell suspension culture and plant regeneration of a Brazilian plantain, cultivar Terra.
The objective of this study was to establish cell suspension culture and plant regeneration via somatic embryogenesis of a Brazilian plantain, cultivar Terra Maranhão, AAB. Immature male flowers were used as explant source for generating highly embryogenic cultures 45 days after inoculation, which were used for establishment of cell suspension culture and

9. In Vitro Regeneration of Arachis Villosulicarpa Hoehne from Cotyledon Segments, Leaves and Cell Suspension.
In vitro regeneration from immature leaves and cotyledon segments of A. villosuli-carpa Hoehne was obtained on Murashige & Skoog medium (1962) plus 1.0 mg/l 1-naphthalene acetic acid (NAA) and 1.0 mg/l 6-benzylaminopurine (BAP). Cotyledon segments showed higher morphogenetic potential than immature leaves. Morphogenic calli could also be obtained from leaves

10. Jasmonic acid elicits oxidative defense and detoxification systems in Cucumis melo L. cells
This study investigated whether a jasmonic acid (JA) elicitation strategy developed in a conventional cell suspension culture could evoke melon resistance mechanisms, including secondary metabolite production. Twenty one day cultured melon cell suspensions grown in MS1 medium were supplemented with JA at the concentrations of 0.5, 5.0 and 10 µmol. Melon cul

11. Estratégias de Produção in vitro de Bioinseticida Viral: influências do Isolado, da Cinética e do Modo de operação
Societal concerns about environmental sustainability has lead to the development of ecologically-friendly alternatives to chemical insecticides for crop protection. One such alternative is biological pest control. In particular, baculoviruses are well suited as insect biopesticides due to their narrow host specificity and relative ease of propagation. In Bra

12. Ferritin gene expression and antioxidant response of two Coffea arabica cultivars exposed to iron and aluminium / Expressão de genes da ferritina e resposta antioxidante em duas cultivares de Coffea arabica expostas a ferro e aluminio
Ferritin is a protein capable to store iron (Fe) atoms in a nontoxic form, controlling the level of this metal in the cells. In humans, ferritin is able to accommodate aluminium (Al) atoms, avoiding its toxicity. Considering that Coffea arabica plants are able to grow well in acidic soils with high Al and suspension cells treated with this same metal showed
