13. Identification of differentially expressed genes of Xanthomonas axonopodis pv. citri by representational difference analysis of cDNA
Xanthomonas axonopodis pv. citri is a phytopathogenic bacterium responsible for citrus canker, a serious disease which causes severe losses in citriculture around the world. In this study we report the differential expression of X. axonopodis pv. citri in response to specific treatments by using Representational Difference Analysis of cDNA (cDNA RDA). cDNAs

14. Modelagem espaço-temporal para dados de incidência de doenças em plantas. / Spatiotemporal modelling of plant disease incidence.
The information about the spatial-temporal dynamics is of fundamental importance in epidemiological studies for describing and understanding the development of diseases, for developing efficient sampling plans, for planning controlled experiments, for evaluating the effect of different treatments, and for determining crop losses. The Citriculture is the majo

15. Genetic transformation of citrus with bacterio-opsin (bo), cecropin and gus genes. / Transformação genética de citros com os genes bacteriopsina (bO), cecropina e gus.
Application of modern biotechnology techniques, as genetic transformation, has helped breeding programs of perennial plant species. This technique is already successfully used in citrus in several countries, mostly to the production of more disease-tolerant plants. Present work had three objectives as it follows: 1. genetic transformation of Rangpur lime roo

16. Produção de flavonoides e atividade oxido nitrico sintase na resposta de defesa de soja ao fungo causador do cancro da haste
The formation of phytoalexin is part of the defense mechanism of soybeans against the fungus Diaporthe phaseolorum f. sp. meridionalis (Dpm), the causal agent of stem canker disease. In this work, the involvement of nitric oxide synthase (NOS) in phytoalexin production was examined. Phytoalexin formation and NOS activity in soybean cotyledons stimulated with

17. Requirement for Phosphoglucose Isomerase of Xanthomonas campestris in Pathogenesis of Citrus Canker
A mutant (XT906) of Xanthomonas campestris pv. citri, the causal agent of citrus canker, was induced by insertion of the transposon Tn5tac1 and isolated. This mutant did not grow or elicit canker disease in citrus leaves but was still able to induce a hypersensitive response in a nonhost plant (the common bean). The mutant was also unable to grow on minimal

18. Apoptosis: A Functional Paradigm for Programmed Plant Cell Death Induced by a Host-Selective Phytotoxin and Invoked during Development.
The host-selective AAL toxins secreted by Alternaria alternata f sp lycopersici are primary chemical determinants in the Alternaria stem canker disease of tomato. The AAL toxins are members of a new class of sphinganine analog mycotoxins that cause cell death in both animals and plants. Here, we report detection of stereotypic hallmarks of apoptosis during c

19. Expression of the antiapoptotic baculovirus p35 gene in tomato blocks programmed cell death and provides broad-spectrum resistance to disease
The sphinganine analog mycotoxin, AAL-toxin, induces a death process in plant and animal cells that shows apoptotic morphology. In nature, the AAL-toxin is the primary determinant of the Alternaria stem canker disease of tomato, thus linking apoptosis to this disease caused by Alternaria alternata f. sp. lycopersici. The product of the baculovirus p35 gene i
