Project Details
Description
The pineapple crop is of great importance at the national level, being the second crop with the
greatest impact on the national economy, mainly because of the income it generates in the
European and United States markets. The Ananas comosus plant, pineapple, has a very poorly
developed root system, limiting the use of soil resources for good vegetative development and
production, forcing producers to use large amounts of agrochemicals to solve this deficiency, in
addition, being a system of extensive monoculture production has been associated with multiple
environmental problems that affect the ecology and health of people in the areas surrounding the
planting areas.
Mycorrhizal fungi are soil organisms with the capacity to interact closely with plant roots, achieving
an exchange of nutrients and signals that modulate plant response to different stress conditions.
This exchange of molecules has also been detected among mycorrhizal plants, mediated by the
mycorrhizal fungus. Findings have been made both at the level of nutrient exchange and stress
response signaling molecules. Therefore, the study of plant-mycorrhizal-plant interaction is
proposed in order to understand the role they play in the response to stress and their potential as
biofertilizers that allow a better use of soil resources and a reduction in the use of agrochemicals in
pineapple plantations. This study is intended to be carried out through the design of a plantmycorrhizal-plant interaction model that allows the induction of stress in one of the plants and the
measurement of the response in the non-stressed plant mediated by the mycorrhizal
interconnection.
