Leprosis is a complex pathosystem that comprises a virus that does not spread systemically within its hosts, an unusual mite vector, Brevipalpus sp., and an ever-growing list of hosts. Although reported more than one century ago, the increasing importance and losses caused by the disease to the citrus industry in the Americas have led to the intensification of the studies on leprosis. In the last decade, most of what was accepted about CiLV-C and its interactions with the host and the vector was shown to be inaccurate. Our data bring novel information on the virus-vector relationship (believed to be propagative and now shown to be of circulative manner) as well as the virus-host interaction (initially thought to be a HR-type of resistance and now shown to be a typical compatible host-virus interaction). In order to understand the mechanisms involved in the response of susceptible and resistant citrus genotypes to the virus, we performed a genome-wide study using a customized microarray chip containing ~32,000 unigenes from Citrus sinensis. Analysis was done to identify the most representative metabolic pathways using Arabidopsis thaliana Gene Ontology as basis. The differentially expressed genes were compared to Arabidopsis thaliana submitted to biotic stress microarray experiments with the software Genevestigator. From these comparisons, 50 genes were selected and are being validated by RT-qPCR. |

Abstract - The selection of rootstocks presenting traits of interest, such as resistance to pests and diseases, and compatibility with scion capable of producing fruits attractive to the market, has revolutionized fruit crops worldwide. However, the enormous potential of plants to be selected based on their nutrient uptake efficiency is yet to be properly explored; it can be done based on knowledge about kinetic parameters such as Influx, Maximum uptake velocity, Constant ion affinity with the carrier, and Minimum concentration. The adaptation of a methodology elaborated for annual crops to set kinetic parameters, as well as the Brazilian development of the Influx software, enabled selecting not only peach rootstocks with different nutrient uptake capacities, but also observing the influence the grafting of a particular cultivar crown has on rootstock?s ability to uptake a given nutrient from the soil. Thus, fruit tree rootstocks and cultivars can always be selected based on traits desired by fruit growers and consumers, with emphasis on yield and quality of fruits. They can also be more efficient in taking up nutrients from low natural-fertility soils that require lower nutrient amounts, a fact that increases fertilizer use rationalization and reduces environmental contamination processes resulting from excessive nutrient applications. Index terms: mineral nutrition of fruit trees, fertilization, cultivars, nutrient influx. Resumo - A seleção de porta-enxertos com características de interesse, como resistência a pragas e doenças, e compatibilidade com copa capaz de produzir frutos atrativos ao mercado, revolucionou as frutíferas em todo o mundo. No entanto, o enorme potencial das plantas de serem selecionadas com base em sua eficiência de absorção de nutrientes ainda não foi devidamente explorado; isso pode ser feito com base no conhecimento dos parâmetros cinéticos, como influxo, velocidade máxima de absorção, constante de afinidade do íon com o transportador e concentração mínima. A adaptação de uma metodologia elaborada para safras anuais, para definição de parâmetros cinéticos, bem como o desenvolvimento brasileiro do software Influx possibilitaram não só selecionar porta-enxertos de pessegueiro com diferentes capacidades de absorção de nutrientes, mas também observar a influência da enxertia de uma determinada cultivar copa na capacidade do porta-enxerto de absorver determinado nutriente do solo. Assim, porta-enxertos e cultivares de árvores frutíferas sempre podem ser selecionados com base em características desejadas pelos fruticultores e consumidores, com ênfase na produtividade e na qualidade dos frutos. Eles também podem ser mais eficientes na absorção de nutrientes de solos de baixa fertilidade natural que requerem maiores quantidades de nutrientes, fato que pode aumentar a racionalização do uso de fertilizantes e reduzir os processos de contaminação ambiental resultantes de aplicações excessivas de nutrientes. Termos para indexação: Nutrição mineral de frutíferas, adubação, cultivares, influxo de nutrientes.
