1. Antifungal potential of essential oils from two varieties of Citrus sinensis (lima orange and bahia navel orange) in postharvest control of Rhizopus stolonifer (Ehrenb.: Fr.) Vuill.
Abstract Brazil, the world’s largest citros producer, yields around 19 million tons per year and exports most part of its production as orange juice. Essential oils (EOs) extracted from leaves, fruit and flowers of many species of the genus Citrus have been widely used as the result of their promising bioactivities. The fungus Rhizopus stolonifer (Ehrenb.)

2. Advances in citrus propagation in Brazil
Resumo A citricultura é uma atividade agrícola de grande expressão mundial, ocupando posição de destaque no Brasil entre as frutíferas com elevado volume e valor de produção para o mercado interno de frutas frescas e para exportação de suco concentrado. Considerando as limitações de ordem técnica do agronegócio dos citros, principalmente as am

3. Chemical composition and antibacterial activity of essential oils from Citrus aurantifolia leaves and fruit peel against oral pathogenic bacteria
ABSTRACT Tooth decay is a major public health problem which affects a large number of people in several countries. Even though more than 700 bacterial species have been detected in the oral cavity, Streptococcus and Lactobacillus stand out as the genera that cause tooth decay and other periodontal diseases. In this study, essential oils from Citrus aurantifo

4. A protein expression system for tandem affinity purification in Xanthomonas citri subsp. citri
Abstract Citrus canker, caused by the Gram-negative bacterium Xanthomonas citri subsp. citri (Xac), is one of the most devastating diseases to affect citrus crops. There is no treatment for citrus canker; effective control against the spread of Xac is usually achieved by the elimination of affected plants along with that of asymptomatic neighbors. An in dept

5. Estudo da variação do perfil químico de laranja pêra e tangor Murcott após a inoculação do fungo Alternaria alternata
This paper describes the study of variation in the chemical profile of citrus after inoculation of the fungus Alternaria alternata, who causes the disease known as alternaria brown spot (ABS), which is one of the most serious diseases in orchards of tangerines, causing major damage to the Brazilian citrus. For this, A. alternate was inoculated in sweet orang

6. Resposta de genótipos de citros à leprose e variabilidade genética da ORF p29 do vírus da leprose dos citros C (CiLV-C) / Response of citrus genotypes to leprosis and genetic variability of ORF p29 from Citrus leprosis virus C (CiLV-C)
Viruses have, potentially, broad genetic variability because of their need to adapt to several changes that they are exposed to. Therefore, genetic variability is essential for their survival; it is the first step to adapt to a new host, to break resistance down, to change symptoms and virulence, which justifies the interest in studies in this area. These st

7. Ocorrência de HLB e caracterização de Candidatus Liberibacter spp. no estado do Paraná
Huanglongbing (HLB) is considered the most important disease for citrus production around the world. Three bacteria species are associated with HLB, Ca. Liberibacter africanus, Ca. Liberibacter asiaticus and Ca. Liberibacter americanus. In Brazil, the disease was first reported in 2004, in the State of São Paulo. In Parana, HLB was reported for

8. 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

9. Estudo da transmissão de Candidatus Liberibacter spp. por sementes em citros
Resumo: Huanglongbing (HLB) é considerada a mais destrutiva doença da citricultura, e está disseminada nos principais países produtores de citros. O HLB está associado a bactérias limitadas ao floema, compreendendo Candidatus Liberibacter spp.. A disseminação desta bactéria ocorre naturalmente por meio de inseto vetor, no entanto uma planta sadi

10. Comparative analysis for quantification of Citrus Variegated Chlorosis in the field
Citrus Variegated Chlorosis (CVC) caused by Xylella fastidiosa is one of the most important diseases for Brazilian citriculture. The CVC is a vascular disease with a long incubation period and symptoms similar to other disorders, and this factors difficult the CVC quantification in the field. Two methods of CVC assessment were compared in this study. The fir
