abstract = {Resistance to Xylella fastidiosa was evaluated in 264 hybrids of crosses between Murcott tangor (Citrus reticulata × Citrus sinensis) and Pera sweet orange (C. sinensis) under field conditions. Uninfected hybrids were grafted with buds collected from Pera sweet orange plants infected with X. fastidiosa, forming a plant with two scions (i.e., hybrid branches and Pera sweet orange branches). From these plants, we chose 10 genotypes with three biological replicates. We evaluated gene expression, bacterial multiplication, and citrus variegated chlorosis (CVC) symptom development in both scions. X. fastidiosa was not detected in most hybrid scions and none showed disease symptoms. In contrast, all Pera sweet orange scions were infected with X. fastidiosa and expressed symptoms of CVC. We quantified the expression of 12 defense-related genes by qPCR comparing resistant to susceptible scions. We suggest that some of these genes are involved in resistance of the hybrids to X. fastidiosa, since their expression was significantly higher in the resistant hybrid scions than in tolerant hybrids and scions originated from CVC symptomatic Pera sweet orange buds. However, we note that these data should be interpreted carefully, as the plant genotypes tested are related but necessarily distinct (hybrids of C. reticulata and C. sinensis, in relation to a C. sinensis control). A principal component analysis revealed a relationship between the expression of these genes and hybrid scions, and between scions that originated from infected buds and the presence of the bacteria and plant symptoms. Multiyear field trials are necessary to develop plant resistance to X. fastidiosa. While the experimental design used here had limitations, it allowed us to identify a set of genes potentially involved in Citrus sp. resistance to this pathogen. Future work on the role of these genes in plant defenses to X. fastidiosa infection is necessary to confirm their importance in the displayed resistance phenotype.},

abstract = {Introduction -The tangor cv. Ortanique presents positive characteristics for the fresh fruit export market, however little is known about this genotype in Brazil. In this study, we evaluated the ideal harvest time on two rootstocks, the fruit juice carotenoid content and possible postharvest storage of 'Ortanique' fruit. Materials and methods -The cultivar was grafted on 'Swingle' citrumelo and Poncirus trifoliata and was evaluated to the following variables: plant height, diameter and canopy volume, fruit physical and chemical quality [mass, soluble solids (SS), titratable acidity (TA) and the ratio (SS/TA)], production and productive efficiency in each graft combination. Carotenoids content of 'Ortanique' fruit juice grafted on 'Swingle' was qualified by HPLC. The optimal storage time of 'Ortanique' (with or without wax, stored at 10 °C or at room temperature) were determined for six weeks storage. Results and discussion -The rootstock 'Swingle' provided great growth and plant production of 'Ortanique' plants while Poncirus trifoliata delayed fruit maturation. The 'Ortanique' fruit juice contained high levels of β-cryptoxanthin and cis-violaxanthin and the fruit could be stored at 10 °C for six weeks without losing quality. Conclusion -The 'Ortanique' tangor has productive potential for commercial cultivation in Brazil, being late-maturing, its fruit high in carotenoid content and possibly well adapted to long storage for export.},
