1. Effects of Citrus Sudden Death Disease on Fatty Acid Profile of Orange Tree Bark
Citrus sudden death (CSD) is a disease that has affected millions of orange trees in Brazil, leading to economic losses in the order of billions of US dollars. This article examines the effects of CSD on the fatty acid composition of triacylglycerides (TAG) extracted from rootstock and scion bark. The fatty acid profile determined by gas chromatography showe

2. Sunki mandarin and Swingle citrumelo as rootstocks for rain-fed cultivation of late-season sweet orange selections in northern São Paulo state, Brazil
ABSTRACT In Brazilian regions affected by the citrus sudden death disease, sweet orange cultivation depends on the use of resistant rootstocks. Rangpur lime was mainly replaced by Swingle citrumelo and Sunki mandarin rootstocks, more drought-sensitive ones. The diversification of scion selections is also desirable aiming at the increasing demand for not from

3. Tentativas de purificação e produção de antissoro contra o vírus da morte súbita dos citros e isolamento do CSDaV em plantas herbáceas / Attempts to purify and produce antiserum against the citrus sudden death associated virus and CSDaV isolation in herbaceous plants
Citrus sudden death (CSD) disease was identified in 2001, at Comendador Comes County, State of Minas Gerais, Brazil. Since then the disease has caused the death of 4 million trees in Southwestern Minas Gerais State and Northern São Paulo State. This new and destructive disease affects sweet orange as well as other species, varieties, and hybrids when grafte

4. Construção de cDNA infeccioso de Citrus Sudden death-associated virus
The orange is an important fruit, widely spread around the world and very well suited to the climate in Brazil. However, citriculture has suffered a lot with a new disease, called Morte Súbita dos Citros (MSC) (Citros Sudden Death Disease) that has been recognized the first time in 2001 in Minas Gerais State, Brazil. The disease cause severe damages to plan

5. Caracterização molecular e avaliação da resistência ao vírus da tristeza dos citros (CTV) em plantas transgênicas de laranja Valência(Citrus sinensis L. Osbeck) / Molecular characterization and resistance evaluation to citrus tristeza virus (CTV) in transgenic plants of Valência orange (Citrus sinensis L. Osbeck)
In Brazil, citrus is one of the most important cultures. The productivity of this culture in the country is still considered low and this fact is due to several pests and diseases that affect the crop. Among the diseases there is the tristeza, caused by Citrus tristeza virus (CTV). This pathogen can also be related with another important disease, the citrus

6. Autologistic model in the study of spatial patterns in citrus diseases / Modelo autologístico no estudo de padrões espaciais em doenças de citros
The citrus industry is a major agricultural activity in Brazil and the state of Sao Paulo concentrates the largest production area of oranges in the world. The knowledge of incidence patterns of citrus diseases in time and space is relevant to the industry and allows the description of the dynamics of these diseases and may indicate strategies for epidemics

7. Diagnóstico de doenças de citros utilizando espectroscopia de fluorescência / Diagnosis of citrus diseases using fluorescence spectroscopy
Currently the largest portion of money applied to citriculture focus on health of the orchard. The phytosanitary costs, along with fertilizers, exceed 60% of the production cost. The control of diseases such as Sudden Death of Citrus (SDC), Decline and Greening, also known as Huanglongbing, is done by visual inspection, which confers to the method a high lev

8. In vitro organogenesis in sour orange (Citrus aurantium L.) and genetic transformation of Rangpur lime (Citrus limonia L. Osbeck) and Valencia sweet orange (Citrus sinensis L. Osbeck) with the Marafivirus replicase gene / Organogênese in vitro em laranja azeda (Citrus aurantium L.) e transformação genética de limão Cravo(Citrus limonia L. Osbeck) e laranja Valência(Citrus sinensis L. Osbeck) com o gene da replicase do Marafivirus
Embora desfrute de inegável importância econômica, os citros estão sujeitos a muitos problemas sanitários sendo alguns, limitantes para o cultivo como é o caso das doenças causadas por vírus. A morte súbita dos citros é uma doença relacionada à combinação copa/ porta-enxerto e manifesta sintomas na região da enxertia sobre porta-enxertos intol

9. Aspectos químicos envolvidos nas interações de Citrus com fitopatógenos / CHEMICAL ASPECTS RELATED TO THE INTERACTION BETWEEN Citrus PLANTS AND PHYTOPATOGENIC FUNGI
This present thesis describes the development of analytical methodologies involving the HPLC-PDA-MS/MS coupling to verify the production of both polar and non-polar metabolites in orange trees produced by grafting Citrus sinensis onto Citrus limonea. By the use of such kind of method, it was possible to verify the production of both polymethoxy and glycosyl

10. Sistemas dinamicos e controladores fuzzy : um estudo da dispersão da Morte Subita dos Citros em São Paulo / Dynamic systems and fuzzy controllers : a study of the dispersion of the Citrus Sudden Death in São Paulo
Citrus Sudden Death is a relatively new disease that has affected and killed sweet oranges grafted on the Rangpur lime. This is a worrying characteristic because the Rangpur lime amounts to 85% of the citrus orchards in São Paulo and the south of "Triângulo Mineiro". It is believed that the disease is caused by a virus transmitted by citrus aphids (vectors

11. Alternative production methods of containergrown citrus nursery trees related to prevention of citrus sudden death disease. / Métodos alternativos de produção de mudas cítricas em recipientes na prevenção da morte súbita dos citros.
Citrus Sudden Death (CSD) is a new disease detected in the citrus industry in São Paulo State, Brazil. It affects all citrus varieties budded on Rangpur Lime (Citrus limonia Osbeck), causing lost of vigor and leaf brightness, root system destruction, yield reduction, degeneration of rootstock phloem tissue and death of plants in few months. CSD has a gr

12. 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
