Description: | Herein, whole genome expression analysis was conducted on rosettes of resistant and susceptible Arabidopsis thaliana accessions challenged with Ralstonia solanacearum. Two disease situations were considered: Col-5 plants inoculated with the virulent GMI1000 strain, as well as Nd-1 plants challenged with the same bacterial strain deleted of the avr PopP2 gene (DeltaPopP2), in both cases developing wilt disease symptoms. In contrast, Nd-1 plants challenged with GMI1000 are fully resistant to the pathogen and served as a control.Samples were harvested at the time of inoculation, as well as at 6, 12, 24 hours -at these times no symptoms were visible-, 5 days after inoculation when the first wilt symptoms became visible (25% of wilted leaves: disease index 1, D1), and finally 8 days after inoculation when 75 % of leaves were completely wilted (disease index 3, D3). |
