Abstract
Fungal infection by Fusarium verticillioides causes substantial reductions in maize yield and grain
quality worldwide. Developing natural resistance in maize genotypes is an effective way to achieve
sustainable control of F. verticillioides in the field, and breeding for resistance may be accelerated
by identifying genes and loci responsible for natural disease resistance. Significant advances
have been made in the development of transcriptomic, genetic and genomic information for maize,
F. verticillioides moulds, and their interactions over recent years. Several quantitative trait loci (QTL)
and single-nucleotide polymorphism markers for resistance to Fusarium deriving from QTL mapping
and genome-wide association studies have been described in three different maize populations:
1. Bi-parental population; 2. Association mapping panel; 3. Multi-parent Advanced Generation Inter
Crosses (MAGIC). To guide the identification of candidate genes within the identified QTL, transcriptomic
and sequencing information have been exploited. Promising candidate genes associated
with disease resistance and pathogen related-mechanisms at the Fusarium resistant loci have been
identified on maize chromosomes 4, 5 and 7. Many of the identified candidates’ genes offer hints to
key metabolic pathways that may have a significant effect on reducing Fusarium infection. Measuring
Fusarium resistance in open field could confirm and support their direct use in maize breeding
either through crosses or genome editing approaches.
