Replacement of CTV-susceptible Sour Orange rootstock by CTV-tolerant ones may have triggered outbreaks of Tetranychus urticae in Spanish citrus.
Agriculture Ecosystems & Environment, 2010Co-Authors: Friederike Bruessow, Josep A. Jacas, María J. Asins, Alberto UrbanejaAbstract:Abstract The two spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae) is a major pest of citrus in Spain. Commercial citrus plants are always propagated asexually by bud-grafting onto a seedling rootstock. During the last 70 years, millions of citrus trees grafted on Sour Orange have been destroyed because of Citrus tristeza virus (CTV). Therefore other rootstocks are nowadays predominant. The aim of this study was to asses the influence of the rootstock on selected life history parameters of T. urticae . Mites were reared on leaves of Citrus unshiu trees grafted on six different rootstocks: Sour Orange, Troyer citrange, trifoliate Orange, Volkamer lemon, Alemow and Cleopatra mandarin. Some parameters (sex ratio, egg hatching and survival) were not affected by the rootstock, whereas many other important ones were (fecundity, oviposition rate, lifespan and development time). These differences may explain the diversity found in the selected life history parameters (net fecundity, generation time and intrinsic rate of increase, r m ). Sour Orange appeared as the worst rootstock for T. urticae ( r m = 0.140). It was closely followed by Troyer citrange and trifoliate Orange (6% and 9% increase in r m , respectively), then by Alemow (35.3% increase in r m ), Volkamer lemon (77.6% increase in r m ) and finally Cleopatra mandarin which yielded an r m 89.1% higher than Sour Orange. These results can explain, at least partially, the increasing prevalence of T. urticae as a pest in Spanish citrus orchards. Furthermore, problems could become much more severe on salt-tolerant rootstocks because of global warming, which is expected to exacerbate the threat of salinity, especially in areas with a semi-arid climate.

Antibacterial activity of polymeric nanofiber membranes impregnated with Texas Sour Orange juice
European Polymer Journal, 2019Co-Authors: Mandana Akia, Cristobal Rodriguez, Luis Materon, Robert Gilkerson, Karen LozanoAbstract:Abstract The antibacterial activity of Nylon 6 nanofiber membranes and commercial gauze pads dipped in Texas Sour Orange juice were evaluated. The Nylon 6 nanofiber mats were developed using a centrifugal spinning technique. The resultant mats were composed of fibers with average diameter of 209 nm, while the average fiber diameter of the commercial gauze pad was 8.73 µm. The dipping solution was composed of 100% Texas Sour Orange juice. The samples were immersed in the solution for 5 min. The antibacterial activity against gram-positive, (Staphylococcus aureus) and gram-negative (Escherichia coli and Salmonella sp.) bacteria were evaluated after one day of culture by measuring the inhibition zones. The bacterial tests demonstrated that the addition of the citrus juice to nanofiber membrane increases the degree of inhibition zones from 5.5 mm to 18.5 mm, however; in case of coated gauze pad samples a maximum inhibition zone up to 16 mm was observed. Cell growth was inhibited in the nanofiber membranes, indicating that the nanofiber mats are amenable to be used as easy to remove wound dressings. These results show promising applications in wound care, especially given that the results were achieved in the absence of a sterilization process.

Texas Sour Orange Juice Used in Scaffolds for Tissue Engineering
Membranes, 2018Co-Authors: Mandana Akia, Cristobal Rodriguez, Luis Materon, Robert Gilkerson, Nataly Salinas, Karen LozanoAbstract:Fine fibers of polyhydroxybutyrate (PHB), a biopolymer, were developed via a centrifugal spinning technique. The developed fibers have an average diameter of 1.8 µm. Texas Sour Orange juice (SOJ) was applied as a natural antibacterial agent and infiltrated within the fibrous membranes. The antibacterial activity against common Gram-positive and Gram-negative bacteria (Staphylococcus aureus and Escherichia coli, respectively) was evaluated as well as cell adhesion and viability. The PHB/SOJ scaffolds showed antibacterial activity of up to 152% and 71% against S. aureus and E. coli, respectively. The cell studies revealed a suitable environment for cell growth and cell attachment. The outcome of this study opens up new opportunities for fabrication of fibrous materials for biomedical applications having multifunctional properties while using natural agents.
