Resistance to Aspergillus ear rot and aflatoxin
… respectively, were evaluated for resistance to ear rot caused by Aspergillus flavus using a pinboard inoculator developed at the University of Illinois. Inbreds used in development of F$\sb1$ hybrids included agricultural experiment station releases, and inbreds from Canada, Europe, Mexico, …

Maize ear rot and associated mycotoxins in western Kenya
… established as the most important crop and cob rot as the most important crop protection problem in Western Kenya. The mean percentage rotten maize grain resulting from cob rot was 19% based on the PRA survey in Kapsabet and Tongaren Divisions and on-farm evaluation of the Kenyan hybrids in …

Resistance to Fumonisins and Fusarium Ear Rot of Corn
The objective of this research was to identify sources of resistance to fumonisin contamination and Fusarium ear rot of corn. This research has (i) identified isolates of F. verticillioides and F. proliferatum that produce high levels of fumonisin contamination under field conditions; (ii) adapted …

Host plant resistance and epidemiology of Fusarium ear rot in maize.
This thesis examines fusarium ear rot epidemiology in maize (Zea mays L.) and host plant resistance to Fusarium species causing ear rot, in eastern Canada, through three major groups of experiments. A three-year disease survey that determines the causal agents of maize ear rot in Ontario; a …

Inheritance of Resistance to Fusarium Ear Rot and Fumonisin Accumulation in Corn
… occurring genetic resistance to Fusarium ear rot and with very low or no fumonisin in grain offer the most cost effective, environmentally friendly and publicly acceptable method of controlling fumonisin in corn-based food products. The objectives of this study were to determine the types …

Resistance to gibberella ear rot in maize: Potential mechanisms and breeding strategies
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2027-05-01

Inheritance of Aspergillus Ear Rot and Aflatoxin Resistance From the Tex6 Corn Line
… production and toward susceptibility for ear rot in both crosses. In the B73 $\times$ Tex6 cross, generation mean analysis indicated additive gene action was the most important type of gene action controlling resistance to ear rot and to aflatoxin production. Mo17 was less susceptible to …

Diallel analysis of diplopodia ear rot resistance in maize and an assessment of the genetic variability of Stenocarpella maydis through isozyme analysis
Diplodia ear rot (DER) of maize (Zea mays L.) caused by the fungus, Stenocarpella maydis (Berk.) Sutton has increased in incidence in localized fields over the past decade. My research focused on screening for resistance by examining the development of DER following inoculations prior to flowering, …

THE HOST-PATHOGEN INTERACTOME AND REGULATORY NETWORKS OF ASPERGILLUS FLAVUS PATHOGENESSIS OF ZEA MAYS: RESISTANCE IN MAIZE TO ASPERGILLUS EAR ROT AND TO AFLATOXIN ACCUMULATION
… level and is controlled by transcriptional and protein interactions. To facilitate the understanding of these mechanisms in Aspergillus flavus and Zea mays, three approaches were taken: 1) the development of a predicted interactome for Z. mays (PiZeaM), 2) the development of co-expression …

QTL IDENTIFICATION FOR MARKER ASSISTED SELECTION OF CORN (ZEA MAYS L.) HUSK TRAITS ASSOCIATED WITH FUSARIUM SPP DISEASES RESISTANCE
Fusarium Ear Rot (FER) caused by Fusarium verticillioides and Gibberella Ear Rot (GER) caused by Fusarium graminearum are two of the most important corn diseases in corn in the Northen Italian environment. These diseases significantly reduce yields and contaminate grain with mycotoxins in …

Stenocarpella Maydis: Identification, Management, and Population Diversity
<p>Diplodia ear rot (DER) has been a persistent corn disease across the Midwest, and in recent years it has become an annual problem. The objectives of this study were to i) develop a molecular assay for the identification of Stenocarpella maydis, causal agent of DER, ii) evaluate the effect of …

MOLECULAR APPROACHES TO ANALYZE HORIZONTAL RESISTANCE AMONG PLANT SPECIES (MAIZE, SOYBEAN, AND ARABIDOPSIS) TO SYNTENIC FUSARIAL PATHOGENS (F. GRAMINEARUM AND F. VIRGULIFORME)
… to syntenic fungal species Fusarium graminearum and Fusarium virguliforme infection in plants was partial, quantitative, and strongly influenced by environmental conditions. However, the molecular mechanisms underlying the resistance are still not fully understood. The objectives of this …

Evaluation of southern African maize germplasm for phytoalexin accumulation following inoculation by Fusarium verticillioides
… Fusarium verticillioides causes Fusarium ear rot in maize, a disease that greatly reduces quantity and quality of annual maize yields. The pathogen produces mycotoxins called fumonisins, which have been linked to adverse health effects in both humans and animals. Maize produces terpenoid …

An investigation of Fusarium verticillioides infection in maize using physiological and molecular approaches
… pathogen that infects maize and causes 'Fusarium Ear Rot' which decreases maize kernel yield and quality. In addition, the fungus produces mycotoxins which contaminate the kernel and upon ingestion have negative health consequences for both people and livestock. To this date, there is still no …

Goss’s wilt and leaf blight of corn: chemical control, residue management and resistance
… due to factors that include continuous maize rotations, reduced tillage which increases debris harboring inoculum and the use of susceptible hybrids. There are several ways that could help control the spread of Goss’s wilt, including chemical control, residue management and the use of …

Stink bug-Fusarium interactions and mitigation of associated mycotoxin contamination of corn in the mid-Atlantic, U.S.
… increased mycotoxin concentrations. Prior research on native and invasive stink bugs has focused on understanding their biology, the damage they cause, and elucidating effective and economic management strategies. However, few studies examined the potential for stink bugs to facilitate fungal …
