| Popis: | Resistant and susceptible coffee varieties were used aiming to unveil genes and proteins putatively involved in the resistance response to Colletotrichum kahawae. Gene expression analysis revealed a stronger induction of recognition, signaling and cell wall modification genes in the resistant variety during fungal penetration. It was also observed the increase of total peroxidase activity and the induction of lignin-forming anionic peroxidase-like gene which was further supported by the increase of an anionic isoenzyme. Peroxidases localized in the walls of host cells at infection sites can be related with cell wall lignification. Altogether, these defence responses contribute to restricting fungal growth. |
