| Abstract | |
The eucalyptus planted forest represents the major percentage among all planted forests in Brazil, mainly for the production of paper and cellulose. However, during its development, the eucalyptus can be attacked by a large number of different pathogens, like the fungus Puccinia psidii, the causer of the eucalyptus rust, main disease that affects the eucalyptus in tropical regions. Thus, in order to study some plant defense mechanisms against the infection of the fungus, this study aimed to analyse the gene expression of some enzymes related to oxidative stress and their activities, and the proteome of resistant and susceptible eucalyptus clones, during the process of infection, colonization and multiplication of the fungus in the plant. We could observe differences in the gene expression at all times studied, mostly at 24 hours after inoculation with the fungus. Besides, with the proteome analysis we could find the very relevant proteins for this study, for instance some proteins related to the oxidative stress and to the plant defense response. (AU) | |
