Résumé

The potato is among the top five food crops with a production of 368 million tonnes according to data provided by FAOSTAT, 2018 (Shi et al., 2021). However, we have limited knowledge of the composition of the endophytic microbe community and their interaction with potato crops. Our main goal is to understand potato plants: holobionts with their associated microbiome. This approach will be useful in the future to develop potato crops based more on interaction with resource-beneficial microbes, thus creating sustainable breeding strategies with the decreasing use of chemical fertilizers and pesticides. In this study, we will use the idea of plant microbiome interaction to understand how microbial diversity in the potato endosphere is influenced by host plant characteristics such as cultivars, stage of development, plant organs as well as environmental factors such as soil, stress and application of fertilizers and pesticides.
