1. Aromatic Polyketides and Macrolides from Microsphaeropsis arundinis
The endophytic fungus Microsphaeropsis arundinis was isolated from the capitula of the tropical plant Paepalanthus planifolius (Eriocaulaceae). The fungus was cultivated in seven different media, and the ethyl acetate extracts were tested against tumor cell lines using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide MTT assay. The culture wa

2. Advances and challenges on the in vitro production of secondary metabolites from medicinal plants
RESUMO A produção de metabólitos secundários de plantas medicinais, também chamados de Compostos Medicinais Derivados de Plantas (PDMC), vem ganhando importância na última década. Concomitante ao aumento do conhecimento sobre as propriedades farmacológicas destes compostos, as plantas da horticultura tornam-se a fonte de biomassa mais importante, su

3. Micropropagation and Cellular Behaviour Changes During in vitro Flowering of Impatiens balsamina
RESUMO: Neste estudo, a micropropagação de Impatiens balsamina foi estabelecida a partir de explantes de caule e parte aérea. Os efeitos do GA3 e da glutationa na morfogênese dessa espécie também foram investigados, de modo a induzir o florescimento in vitro. Verificou-se que a melhor regeneração in vitro de plantas foi obtida em meio MS adicionado c

4. Role of Rhizobia in Suppressing the Root Diseases of Soybean Under Soil Amendment
RESUMO: Os rizóbios são bactérias que vivem no solo, caracterizadas pela capacidade única de colonizar as raízes das culturas de leguminosas, onde formam nódulos de fixação de nitrogênio. Foram acumuladas diversas evidências com o objetivo de identificar os benefícios associados ao uso de rizóbios como agentes de controle biológico contra patóg

5. In vitro evaluation of Eugenia dysenterica in primary culture of human gingival fibroblast cells
Abstract: Eugenia dysenterica is a Brazilian tree investigated for its properties and bioactive compounds, which are believed to have both pharmacological and phytochemical therapeutic effects. The leaves of this tree contain tannins, flavonoids, terpenes, and saponins, with reportedly beneficial effects to the human body. Despite these therapeutic applicati

6. Detection of Somaclonal Variation in Micropropagated and Acclimatized Plantlets of Oryza sativa MRQ 74 from Stem Explants
RESUMO: No sistema de cultura de tecidos de plantas, o fornecimento excessivo de hormônios de crescimento vegetal pode inibir o crescimento e desenvolvimento dos regenerantes e, às vezes, induzir a variação somaclonal. Neste estudo, a concentração ideal de hormônios de crescimento para regeneração in vitro de Oryza sativa L. cv. MRQ 74 foi identific

7. Temperature, pH and carbon source affect drastically indole acetic acid production of plant growth promoting yeasts
Abstract Rhizosphere and phylloplane yeasts are able to produce phytohormones, acting as potential plant growth promoters. The aim of this study was to analyze the production of indole acetic acid (IAA) by yeasts using variations in the culture conditions. The yeasts evaluated were Rhodotorula mucilaginosa and Trichosporon asahii, which were cultivated in a

8. Phytochemical and Morphological Evidences for Shikonin Production by Plant Cell Cultures of Onosma sericeum Willd
ABSTRACT Shoot regeneration, callus growth, and biosynthesis of shikonin in callus cultures of Onosma sericeum were examined. Plant tissue culture was used as an alternative method for increasing the production of shikonin, a secondary metabolite. The isolated cultures were subjected to abiotic factors such as light, plant growth regulators, and nutritional

9. Phytochemical study and anti-inflammatory and antioxidant potential of Spondias mombin leaves
Abstract Spondias mombin L., Anacardiaceae, is a plant native of Brazil, where it is known as "cajá". In order to find a potential application for this native species, the anti-inflammatory and antioxidant effects were investigated. The anti-inflammatory activity was evaluated using the in vivo model carrageenan-induced peritonitis in mice. The in vitro ant

10. Effects of Sodium Nitrate and Mixotrophic Culture on Biomass and Lipid Production in Hypersaline Microalgae Dunaliella Viridis Teod
To access the potential application of Dunaliella viridis Teod. for biofuel production, the effects of culture media composition on biomass and lipid content of this microalgae were investigated. Measured at the 20 th day, sodium nitrate at 5.0 mM augmented biomass production by 26.5 percent compared to control (1 mM sodium nitrate). Total lipids expressed a

11. Somatic embryogenesis in Acrocomia aculeata Jacq. (Lodd.) ex Mart using the thin cell layer technique
Considering the necessity of Acrocomia aculeata propagation for large-scale production, the aim of this study was to establish a somatic embryogenesis protocol using the thin cell layer (TCL) technique. Aerial parts of in vitro plants were transversally cut at the base into eight TCLs and placed in a culture medium for callus induction. The induction medium

12. 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
