In general, popcorn germplasm is less improved than common maize cultivars, with less favorable agronomic performance and greater susceptibility to pests, diseases, and lodging, especially in tropical environments. One approach to expanding and improving popcorn germplasm is to introduce favorable alleles for agronomic performance from field corn. If markers tagging quantitative trait loci (QTLs) associated with popping expansion were identified, they could be selected with markers to maintain popping expansion in breeding populations derived from crosses between field and popcorn germplasm. The objectives of this study were to identify single nucleotide polymorphism (SNP) markers and putative candidate genes associated with higher popping expansion in a diverse sample of popcorn and field corns relevant to Brazilian breeding programs. We applied a comprehensive genome‐wide association study (GWAS) for popping expansion, using 165,089 SNP markers in 183 inbred lines with 2 yr of trial data. Four SNPs were significantly associated with popping expansion, three of which were colocalized to previously reported meta‐QTLs, and one that was novel. Annotated genes closely linked to the associated SNPs were identified with functions related with starch content, which plays an important role in popping expansion quality. If these associations can be validated independently, they can be useful for breeders to select agronomically superior genotypes with greater popping expansion.}, number={5}, journal={CROP SCIENCE}, author={Camargo Senhorinho, Henrique Jose and Dacal Coan, Marlon Matias and Marino, Thiago Pablo and Kuki, Mauricio Carlos and Barth Pinto, Ronald Jose and Scapim, Carlos Alberto and Holland, James Brendan}, year={2019}, pages={2007–2019} } @article{morales_marino_wenndt_fouts_holland_nelson_2018, title={Dissecting Symptomatology and Fumonisin Contamination Produced by Fusarium verticillioides in Maize Ears}, volume={108}, ISSN={["1943-7684"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-85057563477&partnerID=MN8TOARS}, DOI={10.1094/PHYTO-05-18-0167-R}, abstractNote={ The fungus Fusarium verticillioides can infect maize ears, contaminating the grain with mycotoxins, including fumonisins. This global public health threat can be managed by breeding maize varieties that are resistant to colonization by F. verticillioides and by sorting grain after harvest to reduce fumonisin levels in food systems. Here, we employed two F. verticillioides inoculation techniques representing distinct infection pathways to dissect ear symptomatology and morphological resistance mechanisms in a diverse panel of maize inbred lines. The “point” method involved penetrating the ear with a spore-coated toothpick and the “inundative” method introduced a liquid spore suspension under the husk of the ear. We evaluated quantitative and qualitative indicators of external and internal symptom severity as low-cost proxies for fumonisin contamination, and found that kernel bulk density was predictive of fumonisin levels (78 to 84% sensitivity; 97 to 99% specificity). Inundative inoculation resulted in greater disease severity and fumonisin contamination than point inoculation. We also found that the two inoculation methods implicated different ear tissues in defense, with cob morphology being a more important component of resistance under point inoculation. Across both inoculation methods, traits related to cob size were positively associated with disease severity and fumonisin content. Our work demonstrates that (i) the use of diverse modes of inoculation is necessary for combining complementary mechanisms of genetic resistance, (ii) kernel bulk density can be used effectively as a proxy for fumonisin levels, and (iii) trade-offs may exist between yield potential and resistance to fumonisin contamination. }, number={12}, journal={PHYTOPATHOLOGY}, author={Morales, Laura and Marino, Thiago P. and Wenndt, Anthony J. and Fouts, Julia Q. and Holland, James B. and Nelson, Rebecca J.}, year={2018}, month={Dec}, pages={1475–1485} } @article{morales_wenndt_marino_holland_nelson_2017, title={Variation in the Fusarium verticilloides-maize pathosystem and implications for sorting mycotoxin-contaminated maize grain}, volume={107}, number={2}, journal={Phytopathology}, author={Morales, L. and Wenndt, A. and Marino, T. and Holland, J. and Nelson, R.}, year={2017}, pages={11–11} }
