Elucidating the relationships between biochemical composition and resistance to biotic stresses in different climatic scenarios: Impact on maize alternative uses. Convocatoria 2022 - Ministerio de Ciencia e Innovación. PID2021-122196OB-C22. IPs: Rogelio Santiago Carabelos (CSIC)/ José Carlos Souto Otero (Universidad de Vigo). 2022-2025.
The research lines proposed in this project focuses on deepening the knowledge of the biochemical and physiological mechanisms of resistance in the maize crop (Zea mays L.) against various biotic stresses; specifically, against the borer pest (Sesamia nonagrioides Lef.), the contamination with fungi of the genus Fusarium (Fusarium verticilloides Sacc.) and the increase of the attack of the moth Sitotroga cerealella (Olivier). In the project, we will explore the role of the lignin polymer and its monomers composition against resistance to biotic stresses, designing new selection programs that propose modifications in content and composition. We will also advance in the study of defense mechanisms: assessing the response induced after the borer attack; characterizing the lipid profile and its involvement against the dispersion of Fusarium fungi; or evaluating morphological and nutritional characters in the grain against moth’s damage. In the same way, we will investigate into the relationships between components of biotic and abiotic stress, evaluating combined biotic stresses, endophytes, or in a novel way, the effect of water deficit on resistance mechanisms.
We will continue with the clarification of the possible positive or negative interactions between components of the cell wall, resistance to biotic stresses and alternative uses of the maize crop: we will evaluate interferences in the silage and feeding of cattle, and the ethanolic potential through saccharification in promising genotypes for each use. Finally, we will implement new technologies for phenotyping and monitoring pests as a new tool within an integrated pest control management.

Development of maize varieties with double use in a scenario of climate change. Plan Nacional de I + D, Proyectos Orientados a la Transición Ecológica y Digital. TED2021-129405B-I00 IPs: Ana Butrón Gómez/Rogelio Santiago Carabelos. 2022-2024.
The main objective of the proposal is the development of maize varieties with double use, resilient to low-input agriculture and tolerant to stresses related to climate change, contributing this way to promotion of agriculture sustainability. The project is based on a multidisciplinary strategy combining knowledge and tools from the disciplines of crop breeding (MBG-GMM group), biochemistry (MBG-BIOFIC, IRNASA and IdAB groups) and physiology (MBG-BIOFIC, IRNASA and IdAB groups). The specific objectives are:
1. Searching for maize resilient germplasm for dual usage (food/feed and energy). We will assess maize double-use performance under stress conditions brought about by the climate change in a collection of landraces with wide genetic diversity and adapted to European conditions in order to identify varieties that really broaden the narrow genetic diversity of current cultivated varieties and that can be used as sources of tolerance for pre-breeding and breeding programs.
2. Identification of biochemical and physiological traits as new selection targets. High-throughput biochemical and physiological characterization of different inbred lines under stress conditions would render basic knowledge on the physiological and biochemical response of maize to drought and high temperature under different [CO2] and on the ability of spectroradiometric devices to predict cultivar resilience to those stresses, helping on building prediction models of the adaptation response and designing efficient breeding programs for facing climate change.

Capitalization of Mediterranean maize germplasm for improving stress tolerance (DROMAMED). PRIMA call for Research and Innovation Actions (RIA) 2020. IPs UVigo: Rogelio Santiago Carabelos hasta 30/11/2021/ Carlos Souto Otero desde 01/12/2021. Agencia Española de Investigación. Programación Conjunta Internacional. PCI2021-121919. 2021-2024.
Innovative and sustainable farms must face the main challenges of agriculture, with drought and heat being the main environmental constrains worldwide, and this situation may worsen due to climate change. As a whole, the DROMAMED project will collect maize germplasm collections that cover the functional biodiversity available for adaptation to specific environments and resilience to stresses associated with climate change (objective 1). These materials will be evaluated in order to: i) identify genomic regions and candidate genes for stress tolerance (objective 3); ii) provide new knowledge on morphological, biochemical and physiological characteristics (objective 4), to be used as tools to improve the adaptation of maize to various arid agroecological zones of the Mediterranean area (objective 5); and iii) obtain improved varieties for specific areas and, specifically, for more sustainable agricultural systems (objectives 2 and 6).
