“…In general, in citrus fruits propagated by grafting, very good results except for lemon have not been obtained in steel propagation so far (Cooper, 1935). In the study examining the effects of IBA and Paclobutrazol on steel rooting in Valencia orange cultivar, the highest steel rooting (19.6%) was obtained from 500 ppm IBA + Paclobutrazol (Habermann et al, 2006). In the study which investigated the effects of IBA applications on cutting rooting in different citrus rootstocks, trifoliate orange, Carrizo citrange, Cleopatra mandarin, Citrumelo 1452 rootstocks control and different rooting applications could not be detected (Uzun and Seday, 2011).…”

In this study, the effects of Agrobacterium rubi A-18 and Bacillus OSU-142 bacterial strains alone and in combination with 1000, 2000, 4000 ppm IBA on rooting of Carrizo citrange and Troyer citrange citrus rootstock in softwood, semi-hardwood and hardwood cuttings were investigated. In the case of IBA solution, Agrobacterium rubi A-18 and Bacillus OSU-142 were prepared in solution at a concentration of 1x10 9 bacteria / ml and applied to cuttings of citrus. Application were performed in the mist propagation system. Cuttings kept in the fogging environment for 3 months removed at the end of this period, and their rooting rates (%), callus formation rates (%) and survival rates (%) determined. Based on the results of the study, the survival rates and callus formation rates of the cuttings of citrus were generally high at the end of the rooting period. The highest rooting rates in Carrizo citrange cuttings were detected in 4000 ppm IBA and OSU-142 + A-18 (13.33%) treatments for softwood cuttings, 4000 ppm IBA + OSU-142 (20.00%) in semi-hardwood and hardwood cuttings. In the Troyer citrange, OSU-142 + A-18 (6.67%) treatments for softwood cuttings, in 1000 ppm IBA for semi-hardwood, and in 4000 ppm IBA (13.33%) and 1000 ppm IBA treatment for hardwood cuttings, 2000 ppm IBA and OSU-142 (13.33%) the highest rooting has been treatments. According to the cuttings pick-up period, the rooting rates of Carrizo citrange are not different, at the Troyer citrange in the semi-hardwood and hardwood cuttings was higher. As a result, it could be state that plant growth promoting bacteria and IBA applications have not effect on rooting in the softwood, semihardwood and hardwood cuttings of the Carrizo citrange and Troyer citrange citrus rootstocks.

“…The genome sequence determination of the phytopathogenic bacterium X. fastidiosa strain 9a5c was a world landmark. X. fastidiosa-9a5c is associated to citrus variegated chlorosis (CVC) in sweet orange trees (Habermann et al, 2006). It has a main chromosome and two plasmids, composing a total of 2,905 genes.…”

DNA Microarray was developed to monitor the expression of many genes from Xylella fastidiosa, allowing the side by-side comparison of two situations in a single experiment. The experiments were performed using X. fastidiosa cells grown in two culture media: BCYE and XDM2. The primers were synthesized, spotted onto glass slides and the array was hybridized against fluorescently labeled cDNAs. The emitted signals were quantified, normalized and the data were statistically analyzed to verify the differentially expressed genes. According to the data, 104 genes were differentially expressed in XDM2 and 30 genes in BCYE media. The present study showed that DNA microarray technique efficiently differentiate the expressed genes under different conditions.
DNA Microarray foi desenvolvida para monitorar a expressão de muitos genes de Xylella fastidiosa, permitindo a comparação de duas situações distintas em um único experimento. Os experimentos foram feitos utilizando células de X. fastidiosa cultivada em dois meios de cultura: BCYE e XDM2. Pares de oligonucleotídeos iniciadores foram sintetizados, depositados em lâminas de vidro e o arranjo foi hibridizado contra cDNAs marcados fluorescentemente. Os sinais emitidos foram quantificados, normalizados e os dados foram estatisticamente analisados para verificar os genes diferencialmente expressos. De acordo com nossos dados, 104 genes foram diferencialmente expressos para o meio de cultura XDM2 e 30 genes para o BCYE. No presente estudo, nós demonstramos que a técnica de DNA microarrays eficientemente diferencia genes expressos sob diferentes condições de cultivo
