1. Caracterização taxonômica de espécies do gênero Xanthomonas / Taxonomic characterization of Xanthomonas species
Xanthomonas species are responsible for diseases causing economic losses in many crops. These phytopathogens have been subject of several taxonomic studies resulting in significant changes at interespecific or infraspecific level. This study aimed the taxonomic characterization of Xanthomonas species including: (1) differentiation and phylogenetic analysis o

2. Productivity and chemical composition of monoculture and syndications sorghum and corn with green manure at different times of court / Produtividade e composição bromatológica de monocultivos e consorciações de sorgo e milho com adubos verdes em diferentes épocas de corte
The project goal was to study the productivity and quality of forage produced bromatological from monoculture of sorghum and maize and intercropping of them with dwarf pea, sunn hemp, white lupine, sunflower and radish. The experiment was installed in the area of agricultural production of the Campus II Unoeste in Presidente Prudente-SP, on April 3rd, 2008.

3. Performance and host preference of Ascia monuste (Lepidoptera, Pieridae) wild immatures in food change and deprivation of different hosts / Performance e preferência de imaturos selvagens de Ascia monuste (Godart, 1819) (Lepidoptera, Pieridae) na mudança e na privação de hospedeiros alimentares diferentes
Ascia monuste (Lepidoptera, Pieridae) caterpillars are Brassicaceae specialists, being one of the most important comsumers of this plant family in the Neotropical region. In the field, a high proportion of immatures migrates to other hosts in order to develop properly, probably facing some variation in terms of nutritional value and location of their hosts.

4. CaracterizaÃÃo da variabilidade natural da resposta a um isolado brasileiro de Xanthomonas campestris pv. campestris em Arabidopsis thaliana
Phytopathogens are problems for agriculture as they reduce both crop quality and quantity. Chemicals are frequently used to control plant pathogens. However, they are undesirable because of increased production costs to farmers as well as environmental and consumer health negative impacts. An alternative to the use of chemicals is the development of varietie

5. Fisiologia de Bacillus subtilis R14 sob condiÃÃes restrita e irrestrita de oxigÃnio: produÃÃo de compostos bioativos e esporulaÃÃo
Several strains of Bacillus subtilis produce lipopeptides, which are amphiphilic compounds with surfactant and antimicrobial activities. Production of lipopeptide, sporulation and competence in B. subtilis are interconnected through a complex array of controlling elements. The aims of this study were to evaluate the activity of B. subtilis R14 against severa

6. Production of a biocontrol agent for crucifers black rot disease
Of nine epiphytic isolates of the genus Bacillus, only B. subtilis R14, B. pumilus C116, B. megaterium pv. cerealis RAB7, and B. cereus C210 showed antibiotic activity when tested in vitro against the bacterium Xanthomonas campestris pv. campestris LFR-3. Aiming product a biocontrol agent for black rot in crucifers, the production of B. subtilis R14 was eval

7. ProduÃÃo de substÃncias bioativas de Bacillus spp. contra Xanthomonas campestris pv. campestris
The genus Bacillus is one of the most commonly used for the biocontrol of plant diseases. These microorganisms are easily found inhabiting soil and plants and form spores tolerant to heat and dryness, which facilitates its commercialization and stock. One of the main mechanism of action of these microorganisms in the biocontrol of phytopathogens is the produ

9. Involvement of Cytochrome P450 in Glucosinolate Biosynthesis in White Mustard (A Biochemical Anomaly).
One of the first steps in glucosinolate biosynthesis is the conversion of amino acids to their aldoximes. The biochemistry of this process is controversial, and several very different enzyme systems have been described. The major glucosinolate in white mustard (Sinapis alba) is sinalbin, which is derived from tyrosine via its aldoxime, and this conversion is

10. Self-Incompatibility in the Genus Arabidopsis: Characterization of the S Locus in the Outcrossing A. lyrata and Its Autogamous Relative A. thaliana
As a starting point for a phylogenetic study of self-incompatibility (SI) in crucifers and to elucidate the genetic basis of transitions between outcrossing and self-fertilizing mating systems in this family, we investigated the SI system of Arabidopsis lyrata. A. lyrata is an outcrossing close relative of the self-fertile A. thaliana and is thought to have

11. Dark Reversion of Phytochrome in Sinapis alba L. 1
Phytochrome in Sinapis alba L. (white mustard) seedlings undergoes both decay and reversion after an exposure to red light. This is typical of other crucifers and of dicotyledons in general. In the presence of sodium azide, decay is inhibited, and reversion continues at about the same rate as in buffer alone. The reversion has been demonstrated both in cotyl

12. Antibacterial Activity of Sirodesmin PL Phytotoxin: Application to the Selection of Phytotoxin-Deficient Mutants
Sirodesmin PL, a phytotoxin and mycotoxin produced by Leptosphaeria maculans, the causal agent of stem-canker disease of crucifers, exhibited antibacterial activity against gram-positive bacteria and particularly Bacillus subtilis. The importance of the disulfide bridge of the molecule in antibacterial activity was demonstrated. A simple and reliable bioassa
