• Abstract

  Citrus is affected by several phytopathological problems that interfere with the crop productivity. The Huanglongbing (HLB) associated with Candidatus Liberibacter spp., which colonizes the phloem, was detected in Brazilian orchards and is causing several problems to the crop. The development of resistant cultivars through genetic transformation is been considered a valuable approach in...

• Abstract

  Virus diseases can be considered the main problem affecting cucurbits production. These diseases reduce productivity and fruit quality. In Brazil, 8 virus were described affecting cucurbits. Papaya ringspot virus type W (PRSV-W) and Zucchini yellow mosaic virus (ZYMV) are considered the most important virus diseases of these crops, occurring in all cultivated areas. The control of these...

• Abstract

  Genetic transformation is an alternative to conventional breeding allowing the introduction of genes that can influence the resistance of plants to diseases. The most used method for genetic transformation of citrus is Agrobacterium tumefaciens. In this method, the T-DNA containing the gene of interest driven by a promoter, is transferred to the plant. Among the promoters usually employ...

  Citrus sinensis constitutive gene promoters: isolation and evaluation of its efficiency on uidA gene expression in Solanum Lycopersicum and citrus sinensis, BP.DR

• Abstract

  Citrus fruits are the first in fruit production volume in Brazil, especially the production of sweet oranges. Nevertheless, the productivity of citrus in the country is still low compared to the one obtained in other producing countries. This low productivity is due, among other factors, to the occurrence of diseases in the culture. Among the major diseases are citrus tristeza caused by...

  Evaluation of somatic hibrids and transgenic plants of Citrus spp. for disease resistance, BP.PD

• Abstract

  Citrus has a wide genetic diversity and the group of mandarins is that which corresponds to the highest. In Brazil, citrus production is an important segment in the socio-economic structure, characterized as an important industrial activity, qualifying the country in recent decades as the world's largest producer of oranges and the largest producer and exporter of frozen concentrated ju...

• Abstract

  Transgenic technology can provides genetic solutions to major problems affecting citrus species. The success of gene transfer technologies depends on the selection of appropriate promoter that induces expression of transgene at desired levels. Among the promoters usually employed, there is the constitutive promoter CaMV35S isolated from the Cauliflower Mosaic Virus characterized by the ...

  Characterization of regulatory elements in citrus derived promoters, BE.EP.DR

• Abstract

  Citrus has extensive genetic diversity and the group of mandarins corresponds the largest. In Brazil, the citrus industry is an important segment in the socio-economic structure, characterized as an important agro-industrial activity. The traditional breeding has presented limitations to obtaining new varieties of rootstock and scion, due to the discontinuity in programs established and...
