1. Aspects of seeds germination and influence of light on the development, leaf anatomy and chemical composition of essential oil in Ocimum gratissimum L. / Aspectos da germinaÃÃo das sementes e influÃncia da luz no desenvolvimento, anatomia foliar e composiÃÃo quÃmica do Ãleo essencial em Ocimum gratissimum L.
Before the need to deepen the knowledge about medicinal flora, the species Ocimum gratissimum L., an important producer of essential oil much utilized as a phytotherapeutic, was selected. The main objectives in this work were to evaluate physiologic aspects of germination and storage of seeds as well as to investigate growth leaf anatomy and accumulation of

2. Obtenção de extratos vegetais com propriedades funcionais via tecnologia supercritica : uso de CO2 e CO2 + H2O. / Vegetal extracts with functional properties obtained using supercritical technology : use of CO2 and CO2 + H2O.
In this work supercritical fluid extraction was used to obtain extracts from Ocimum basilicum (sweet basil), Achyrocline alata, and Achyrocline satureioides; for sweet basil extracts, water was used as cosolvent at 1, 10, and 20% (v/v). The extract?s global yield isotherms, chemical compositions, and antioxidant activities were determined. The extraction ass

3. Effect of the essential oils of seasonings on the growth of Staphylococcus aureus in creamy ricotta / Efeito de Ãleos essenciais de condimentos sobre o crescimento de Staphylococcus aureus em ricota cremosa
Food safety is of general concern, in which consumers look for safe products while industries search for alternatives to increase the life of shelf products with safety. With the culture of the organical products in the globalized world the addition of natural substances for the microbial control has been very used. The seasonings, which were added to victua

4. Pseudomonas aeruginosa-Plant Root Interactions. Pathogenicity, Biofilm Formation, and Root Exudation1
Pseudomonas aeruginosa is an opportunistic human pathogen capable of forming a biofilm under physiological conditions that contributes to its persistence despite long-term treatment with antibiotics. Here, we report that pathogenic P. aeruginosa strains PAO1 and PA14 are capable of infecting the roots of Arabidopsis and sweet basil (Ocimum basilicum), in vit

5. Characterization of Geraniol Synthase from the Peltate Glands of Sweet Basil1
The monoterpene fraction of the lemon-scented sweet basil (Ocimum basilicum) cv Sweet Dani consists mostly of citral (a mixture of geranial and neral), with lower levels of geraniol and nerol. These compounds are stored in the peltate glands found on the leaf epidermis. Younger leaves, which have a higher density of such glands, also have a higher content of

6. Differential Production of meta Hydroxylated Phenylpropanoids in Sweet Basil Peltate Glandular Trichomes and Leaves Is Controlled by the Activities of Specific Acyltransferases and Hydroxylases1
Sweet basil (Ocimum basilicum) peltate glandular trichomes produce a variety of small molecular weight phenylpropanoids, such as eugenol, caffeic acid, and rosmarinic acid, that result from meta hydroxylation reactions. Some basil lines do not synthesize eugenol but instead synthesize chavicol, a phenylpropanoid that does not contain a meta hydroxyl group. T

7. Characterization of Phenylpropene O-Methyltransferases from Sweet Basil: Facile Change of Substrate Specificity and Convergent Evolution within a Plant O-Methyltransferase Family
Some basil varieties are able to convert the phenylpropenes chavicol and eugenol to methylchavicol and methyleugenol, respectively. Chavicol O-methyltransferase (CVOMT) and eugenol O-methyltransferase (EOMT) cDNAs were isolated from the sweet basil variety EMX-1 using a biochemical genomics approach. These cDNAs encode proteins that are 90% identical to each

8. An Investigation of the Storage and Biosynthesis of Phenylpropenes in Sweet Basil1
Plants that contain high concentrations of the defense compounds of the phenylpropene class (eugenol, chavicol, and their derivatives) have been recognized since antiquity as important spices for human consumption (e.g. cloves) and have high economic value. Our understanding of the biosynthetic pathway that produces these compounds in the plant, however

9. The Biochemical and Molecular Basis for the Divergent Patterns in the Biosynthesis of Terpenes and Phenylpropenes in the Peltate Glands of Three Cultivars of Basil1
Surface glandular trichomes distributed throughout the aerial parts of sweet basil (Ocimum basilicum) produce and store monoterpene, sesquiterpene, and phenylpropene volatiles. Three distinct basil chemotypes were used to examine the molecular mechanisms underlying the divergence in their monoterpene and sesquiterpene content. The relative levels of specific
