Hop-Verticillium interactions

Hop-Verticillium interactions

We analyzed proteomic profile of hop roots in control and fungus-infected plants in three time points after inoculation. Responses of susceptible and resistant cultivar were then compared. The profile changed between time points significantly also in control plants, therefore the influences of infection and time were separated using appropriate statistic methods. We found out that infection caused significant quantitative changes in more than a fifth of detectable proteome in susceptible cultivar, while there were no changes in resistant cultivar. Mass spectrometry was used to identify 100 protein spots. As expected, increased production of defence proteins was found in susceptible cultivar, whereas specific forms of a lectin potentially involved in pathogen recognition were identified in resistant cultivar.
