Abstract
Citrus canker is one of the most important diseases for citriculture. The continuous use of copper-based bactericides is the main strategy for controlling citrus canker. However, this practice may be harmful to the environment as a result of the accumulation of copper in the soil, phytotoxicity to citrus plants, and selection of bacterial populations with copper-resistance genes. Moreover…

Abstract
Citrus huanglongbing (HLB), or greening, is the most destructive citrus disease worldwide and is threatening the sustainability of the industry, affecting tree development, production and fruit quality. All Asian citrus species, including all commercial varieties, are susceptible to HLB, but tolerance and resistance have been described in some citrus relatives belonging to the Oceanian ge…

Abstract
The equipment GC-MS/MS approved by Fapesp as a multi-user equipment is a gas chromatography coupled with triple quadrupole tandem mass spectrometry. The gas chromatography (GC) is ideal for applications where is necessary to separate mixtures with high vapor pressure molecules, e.g. volatiles compounds. The injection of these compounds into the GC is possible both in the gas phase and dil…

Abstract
Brazil is the world leader in both orange production and export of concentrated juice. However, a significant volume of orange production has been lost every season due to the attack of diseases, mainly those related to the premature fruit drop. In the citrus belt of São Paulo state (SP), which accounts for 73% of the orange produced in Brazil, the average rate of premature fruit drop rea…

Abstract
Huanglongbing (HLB), a disease mainly associated with the bacterium Candidatus Liberibacter asiaticus, transmitted by the Asian citrus psyllid Diaphorina citri, is present in all citrus production areas of Sao Paulo State. The disease causes severe sweet orange yield losses and fruit quality damages and endangers the sustainability and competitiveness of this important agribusiness genera…

Abstract
Citrus canker is a disease originated from Asia caused by the Gram-negative bacteria Xanthomonas citri subsp. citri (X. citri) which affects all commercial citrus species. Symptoms are similar in diferents parts of plant, with presence of necrotic lesions on leaves, twigs and fruits, reducing quality and production. Furthermore, the presence of the bacteria in orchards impede fruit commer…

Abstract
Huanglongbing (HLB), also known as citrus greening disease, is a highly destructive disease affecting citrus trees worldwide. The causal agent (by association) of the disease is the bacterium Candidatus Liberibacter asiaticus which is transmitted by the Asian citrus psyllid, Diaphorina citri. There is no cure to HLB, the disease has considerable impact on tree growth and development, as w…

Abstract
Currently, huanglongbing (HLB) has severely impacted the citrus industry worldwide due to its rapid spread, reduction in fruit yield and quality, associated with the high cost to manage the disease. Vegetative flushing is the preferred site for feeding and reproduction of the psyllid (Diaphorina citri), the vector of the bacterium Candidatus Liberibacter spp. which is associated with the …

Abstract
The Huanglongbing (HLB) is the most destructive citrus disease worldwide, associated to uncultivated Candidatus Liberibacter species, and spread in citrus orchards by the psyllid vector Diaphorina citri in main citriculture regions such as Brazil, China and Asia in general, the USA and Central America. Although HLB was first described in Brazil fifteen years ago and Candidatus Liberibacte…

Abstract
The ability to express foreign genes or silence endogenous genes in plants has revolutionized both basic and applied plant biology. Systems of expression based on viruses, where the mRNA is greatly amplified by the viral replication can produce very high levels of proteins or peptides in leaves and other tissues. The citrus tristeza virus (CTV) is composed of two capsid proteins and a sin…
