3. Cultivable bacterial diversity associated with bromeliad roots from ironstone outcrops in central Brazil
Resumo Estudos sobre a diversidade bacteriana associada a plantas silvestres são raros, especialmente naqueles que crescem em associação com bromélias. No presente estudo, isolamos e identificamos bactérias epífitas e endofíticas das raízes das bromélias Dyckia excelsa, D. leptostachya e Deuterocohnia meziana ocorrentes nas “cangas” no Pantanal

5. Are we close to knowing the plant diversity of the Amazon?
Abstract: Amazonia is often cited as having the most diverse flora on the planet. However, the total number of species of higher plants in the region has been largely a matter of guesswork. Some recent publications have estimated the total number of species present, which indicate a lower overall diversity than was estimated in the past. However, analysis of

6. 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

7. DIVERSITY OF ARBUSCULAR MYCORRHIZAL FUNGI IN FOREST ECOSYSTEMS OF BRAZIL: A REVIEW
ABSTRACT Plants can stablish symbiosis with arburcular mycorrhiza fungi (AMF), in which the fungus uses carbohydrates synthesized by plant photosynthesis in exchange for soil nutrients. AMF symbiosis may benefit plants by increasing the rates of nutrient uptake, tolerance to abiotic stresses, protection against pathogens and, by promoting resilience of fores

10. Diversity of Plant Species in The Steel City of Odisha, India: Ethnobotany and Implications for Conservation of Urban Bio-Resources
ABSTRACT The vegetation of the Steel City (Rourkela) of Odisha, India has high ethnobotanical values by virtue of its rich floral diversity. People in the urban area are highly dependent on the plants available in and around the city for their primary needs. The present study highlights the use of local flora, explore, identification, ethnobotany and conserv

11. Can the reproductive system of a rare and narrowly endemic plant species explain its high genetic diversity?
ABSTRACT The reproductive system of flowering plants can be highly variable, affecting their biology, gene flow and genetic variability among populations. Petunia secreta is a rare annual endemic species of Pedra do Segredo, located in the municipality of Caçapava do Sul, state of Rio Grande do Sul, Brazil. Although rare, the species possesses a high level

12. Temporal evaluation of the Conservation Priority Index for medicinal plants
ABSTRACT We investigated, through a temporal comparison, the extraction of non-timber forest resources by quantitatively analyzing the Conservation Priority Index (CPI). The study focused on the Fulni-ô Indigenous Territory, in the municipality of Águas Belas, PE (Northeast Brazil), which is characterized by caatinga vegetation (seasonal dry forest). Infor
