Background    Bakanae  disease, caused by seed-borne  Fusarium  species, mainly  F. fujikuroi , is a rice disease whose importance is considerably increasing in several rice growing countries, leading to incremental production losses.    Results  A germplasm collection of  japonica  rice was screened for  F. fujikuroi  resistance, allowing the identification of accessions with high-to-moderate levels of resistance to  bakanae . A GWAS approach uncovered two genomic regions highly associated with the observed phenotypic variation for response to  bakanae  infection on the short arm of chromosome 1 (named as  qBK1_628091 ) and on the long arm of chromosome 4 (named as  qBK4_31750955 ). High levels of phenotypic resistance to  bakanae  were associated to the cumulated presence of the resistant alleles at the two resistance loci, suggesting that they can provide useful levels of disease protection in resistance breeding. A fine comparison with the genomic positions of qBK1_628091 and qBK4_31750955 with respect to the QTLs for  bakanae  resistance reported in the literature suggests that the resistant loci here described represent new genomic regions associated to  F. fujikuroi  resistance. A search for candidate genes with a putative role in  bakanae  resistance was conducted considering all the annotated genes and  F. fujikuroi -related DEGs included in the two genomic regions highlighting several gene functions that could be involved in resistance, thus paving the way to the functional characterization of the resistance loci.    Conclusions  New effective sources for  bakanae  resistance were identified on rice chromosomes 1 and 4 and tools for resistance breeding are provided.
