Mechanisms of defense against biotic stresses in corn. Implications in the improvement for different uses. Programa Estatal de Investigación, Desarrollo e Innovación Orientada a los Retos de la Sociedad. RTI2018-096776-B-C22. PR: Rogelio Santiago Carabelos (Universidad de Vigo). 2019-2021.
RESUME: The research line proposed in this project focuses on deepening in the knowledge of the biochemical mechanisms of resistance in maize (Zea mays L.) against biotic stresses; in particular, to the corn borer pest (Sesamia nonagrioides Lef.) and to the contamination with fungi belonging the Fusarium genus (Fusarium verticilloides Sacc.). Within the different mechanisms of resistance in corn, the role of the cell wall has been investigated with increasing interest over recent years because several of its components, such as cellulose, hemicellulose or phenylpropanoids (lignin or hydroxycinnamates) ) affect the feeding of insects or fungal development from a nutritional or physical point of view. Likewise, these compounds have been widely related to cell stiffness, cessation of growth, enzymatic digestibility, or even recalcitrance in ethanolic production.
In the project we propose the study of all main components of the cell wall and how each component affects aspects of great interest in the multiple use of the crop: resistance to the corn borer pest, digestibility of the crop residue, ethanol production of the same residue, and grain yield.

RESUME: The project addresses a single general objective that is the development of new knowledge to improve maize resistance to biotic stresses, focusing on five sub-objectives: (1) development of breeding programs to obtain resistant varieties, (2) search of genomic regions and genes involved in resistance, (3) study of constitutive and induced defense mechanisms against biotic stresses, (4) study of plant-insect-fungus interaction and (5) monitoring of populations of parasites.
