Fitopatógenos interferem de forma negativa na produção e qualidade final dos produtos agrícolas comercializados. O trabalho tem como objetivo verificar o controle alternativo fungos Cercospora beticola sacc, Phytophthora infestans Colletotrichum lindemuthianum, utilizando as doses 0,2; 0,4; 0,6; 0,8 µL mL-1 do óleo essencial guaçatonga, em comparação a testemunha com somente água. Avaliou- se i...

The potential of hyperspectral measurements for early disease detection has been investigated by many experts over the last 5 years. One difficulties is obtaining enough data training and building a library. When goal to detect at previsible stage, before pathogen manifested either its first symptoms or in area surrounding existing symptoms, it impossible objectively delineate regions interest ...

Comparative transcriptomics between species can provide valuable understanding of plant-pathogen interactions. Here, we focus on wild Solanum species and potato clones with varying degree of resistance against Phytophthora infestans, which causes the devastating late blight disease in potato. The transcriptomes of three wild Solanum species native to Southern Sweden, Solanum dulcamara, Solanum ...

Phytophthora infestans is an oomycete that causes severe damage to potato, and is well known for its ability to evolve rapidly in order to overcome resistant potato varieties. An RNA silencing strategy was evaluated here to clarify if small interfering RNA homologous to selected genes in P. infestans could be targeted from the plant host to reduce the magnitude of the infection. As a proof-of-c...

Soybean beta-1,3-endoglucanase represents a model system for studies on early plant responses to infection by fungal pathogens, and it has been implicated in the release of elicitors from fungal cell walls. In the present study, potato plants were transformed with the soybean beta-1,3-endoglucanase cDNA via Agrobacterium delivery system. The transfer of the gene into potato genome was confirmed...
