1. Agronomic biofortification with iodine in lettuce plants cultivated in floating hydroponic system
ABSTRACT Iodine is essential to human metabolism, being fundamental in the production of the thyroid hormones. The consumption of biofortified foods can contribute to the increase of its intake. The objective of this study was to increase the iodine concentration in lettuce, also evaluating its effects on plant growth and production. The experiment was condu

2. Plant hormones accumulation and its relationship with symplastic peroxidases expression during carnation-Fusarium oxysporum interaction
Resumo A murcha vascular causada por Fusarium oxysporum f. sp. Dianthi (Fod) é a doença mais relevante para o cultivo de cravo. Compreender os mecanismos bioquímicos envolvidos na resistência ao Fod permitirá o desenvolvimento de novas estratégias de controle de doenças. Nesta pesquisa, os níveis de alguns fitohormônios como ácido salicílico (SA),

3. Plant growth-promoting endophytic bacteria on maize and sorghum1
RESUMO Bactérias promotoras de crescimento em plantas (BPCP) são encontradas em tecidos vegetais e promovem o crescimento vegetal por meio da secreção de hormônios e enzimas, ou auxiliando a absorção de nutrientes. Avaliaram-se quarenta isolados de BPCP para determinar seus efeitos sobre o crescimento de milho e sorgo. Estes isolados foram também com

4. Adaptation of plants to high-calcium content kart regions: possible involvement of symbiotic microorganisms and underlying mechanisms
Resumo Os microorganismos e endófitos da rizosfera podem ajudar seus hospedeiros a absorver nutrientes e regular os níveis de hormônios vegetais. Além disso, eles podem modular as expressões dos genes hospedeiros, auxiliar os hospedeiros na eliminação de espécies reativas de oxigênio (ROS) e secretar compostos orgânicos voláteis. Portanto, microor

5. 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

6. Benefits Associated with the Interaction of Endophytic Bacteria and Plants
ABSTRACT The endophytic bacteria belong to a larger group of microorganisms that have their life-cycle partly or entirely inside the plant and are located in intra and inter-cellular spaces or in the vascular tissue. These bacteria can be found colonizing aerial parts or roots. This review aims to analyze the colonization strategies of endophytic bacteria th

7. Mangrove endophyte promotes reforestation tree (Acacia polyphylla) growth
ABSTRACT Mangroves are ecosystems located in the transition zone between land and sea that serve as a potential source of biotechnological resources. Brazil's extensive coast contains one of the largest mangrove forests in the world (encompassing an area of 25,000 km2 along all the coast). Endophytic bacteria were isolated from the following three plant spec

8. Interactions between plant hormones and heavy metals responses
Abstract Heavy metals are natural non-biodegradable constituents of the Earth's crust that accumulate and persist indefinitely in the ecosystem as a result of human activities. Since the industrial revolution, the concentration of cadmium, arsenic, lead, mercury and zinc, amongst others, have increasingly contaminated soil and water resources, leading to sig

9. 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

10. Determination of the regulatory properties of Yucca schidigera extracts on the biochemical parameters and plasma hormone levels associated with obesity
ABSTRACT Yucca schidigera Ortgies, Asparagaceae, is a herbaceous plant. Due to the high saponin content the powdered branches and leaves are used as natural food additive for human and animal. The aim of this study was to investigate the effects of Y. schidigera extracts on plasma leptin, ghrelin, adiponectin, insulin, thyroid hormones and some biochemical p

11. 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

12. Plant biostimulants: physiological responses induced by protein hydrolyzed-based products and humic substances in plant metabolism
ABSTRACT In recent years, the use of biostimulants in sustainable agriculture has been growing. Biostimulants can be obtained from different organic materials and include humic substances (HS), complex organic materials, beneficial chemical elements, peptides and amino acids, inorganic salts, seaweed extracts, chitin and chitosan derivatives, antitranspirant
