Potato is considered a staple food in the world and its production is limited by the presence of bacterial wilt (BW) disease caused by Ralstonia solanacearum. Host resistance is the most sustainable and cost-effective strategy to manage BW, although resistant commercial potato cultivars are not yet available. Our group incorporated the EFR receptor of Arabidopsis thaliana(AtEFR), which recognizes the elongation factor Tu, preserved in bacteria, triggering an immune response. AtEFR was tested in two genetic backgrounds: a susceptible commercial cultivar (INIA Iporá) and a breeding clone with partial resistance introgressed from Solanum commersonii. In this work, the effect of the AtEFR receptor on BW resistance was evaluated for the first time, using conditions resembling natural field infection. In addition, the colonization patterns of wild-type and transgenic lines were compared by using luminescent and fluorescent R. solanacearum reporter strains. Both approaches showed a delay and a decrease in the severity of wilting symptoms in the AtEFR-transformed genotypes. Differential colonization pat-terns were observed, revealing a higher bacterial development in the non-transformed plants. ThisAtEFR effect seems more pronounced in the interspecific breeding line, possibly leading to a more effective activation of the plant immune system. |

Abstract: Neospora caninum is a major reproductive disease in cattle worldwide. In the Argentinian Humid Pampa, the seroprevalence, incidence of abortions, and economic losses due to neosporosis are considerably higher in dairy than in beef cattle. Despite this, we recently demonstrated that N. caninum subpopulations are indistinctly distributed in both dairy and beef production systems. The association between genotypic characteristics defned by microsatellite analysis and the virulence of the different strains?particularly with regard to the severity and extension of histological lesions?is largely unknown. Herein, we used a morphometric approach to analyze encephalic lesions in 62 bovine fetuses spontaneously infected by N. caninum. Morphometric parameters (average size of focal lesions, number of foci/cm2 and the percentage of the section afected by lesions) were compared according to the N. caninum subpopulations found in our previous microsatellite genotyping analysis, animal biotype (beef versus dairy), and fetal age (second stage of gestation versus third stage). The average size of the lesions difered signifcantly among fetuses with diferent gestational ages; however, no signifcant diferences among animal biotypes or genotypic patterns were found. Further research into the genetic, molecular, and husbandry factors that could account for this greater impact in Argentinian dairy herds is needed. |
