Helvecio was graduate at Agronomist by the Universidade Estadual Paulista Júlio de Mesquita Filho in 1989. Concluded his Master's in Science by the Center of Nuclear Energy in Agriculture (CENA) in 1993, and his PHD at Genetics and Molecular Biology by the University of Campinas (UNICAMP) in 2002. Since 2004 his working at Centro de Citricultura Sylvio Moreira (Citrus Research Center) at Cordeirópolis, Sao Paulo, Brazil, from Instituto Agronômico (IAC). His research interest is citrus pathogens with focus in biology, diagnosis and population genetics. . (Source: Lattes Curriculum)
- INCT 2014: comparative and functional genomics and citrus-assisted breeding, AP.TEM
Abstract
Citrus industry is one of the most important activities of the Brazilian agriculture. São Paulo, Sergipe and Bahia are the main citrus producers, and Brazil is by far the main producer and exporter of frozen concentrated (FCOJ) and not from concentrated (NFC) orange juice in the world. The low Brazilian yield (approximately 2 boxes 40.8 kg/tree/year) is strictly associated to the incide...
- Nutritional status and strategic citrus diseases: integrating bases for the management of production, AP.TEM
Abstract
The citrus industry contributes with the volume of fruits produced in Brazilian, obtained with high productivity of orchards, a result of the adoption of technologies such as planting density, fertilization and irrigation. However, the incidence of phytosanitary problems that affect citrus farming has caused the increase of fruit production costs, which leads to a decrease in the sector...
- Xylella fastidiosa in olive oil trees in Brazil: knowing the bacteria and the vectors for the sustainable management, AP.R
Abstract
Earlier restricted to the Americas, the multi-host vector-transmitted bacterium Xylella fastidiosa has now been reported in Europe (southern Italy and France) and Asia (Iran and Taiwan). The devastating impact caused by the outbreak know as Olive Quick Decline syndrome (OQD) associated with X. fastidiosa subsp. pauca in Puglia (southern Italy), the reports of X. fastidiosa subsp. multip...

- Population structure and reciprocal inoculation of Xylella fastidiosa subsp. pauca occurring in neighbor orchards of citrus sinensis and Coffea arabica growing in the São Paulo State, AP.R
Abstract
The bacteria X. fastidiosa is one of the most genomically known microorganisms with significantly advances at molecular levels throught the last ten years. On the other hand a restrict background was accumulated concerning the ecology of this multi-host microorganism that is vectored by a polyphago insect, the sharpshooters of Cicadellini and Preconnini tribes. In the Brazil these bacte...

- Responses of citrandarins (Poncirus trifoliata x Sunki mandarin) to infection by "Candidatus Liberibacter asiaticus", BP.MS
Abstract
Huanglongbing (HLB or greening) is considered one of the most important citrus diseases in the world. The causative agent of HLB is the Gram-negative bacterium named Candidatus Liberibacter spp. of restricted occurrence to the sieve vessels of the host plant phloem and to the vector insect, Diaphorina citri. Although there are no reports in the literature of the existence of completely ...
- Analysis of x. fastidiosa in olive plants in the producing regions of the States of São Paulo and Minas Gerais: occurrence and genetic diversity, BP.MS
Abstract
Xylella fastidiosa (XF) is known for its ability to infect and cause disease in numerous plant species. The most recent host species of this bacterium is olive trees (Olea europea) with reports in southern Italy, where plants with leaf blight had the symptoms associated with infection by X. fastidiosa subsp. pauca (XFp). Reports of the presence of (XF) in olive trees were made in Califo...
