Fusarium verticillioides, an important maize pathogen produces fumonisins and causes stalk and ear rot; thus, we are aimed to clarify its infection cycle by assessing enhanced green fluorescent protein (EGFP) expression in stalk and ear rot strains. 0000002676 00000 n Plant breeding has emerged as an effective and environmentally safe method to reduce fumonisin levels in maize kernels, but although phenotypic selection has proved effective for improving resistance to fumonisin contamination, further resources should be mobilized to meet farmers' needs. The fungus can also spread via infected seed. Infection may occur from late vegetative stages to three weeks after midsilk. However, this ear rot can occasionally develop in uninjured ears of susceptible hybrids. Fusarium ear rot caused by Fusarium fungi that survive on residue of corn and other plants, especially grasses. Studies done until now have provide many markers to be used by breeders, but to get further insight on plant mechanisms to defend against fungal infection and to limit fumonisin contamination, the genes behind those QTLs should be identified. 0000046121 00000 n Decay often begins with insect-damaged kernels. Ear rot, caused by Fusarium spp., is probably the most serious disease of maize in the region, not only because it reduces maize yield, but also because it reduces the nutritional value of infected grains and may induce the development of mycotoxins, threatening human and livestock health.
