“…Newer breeding lines and populations with high and repeatable resistance under varying environments have been released; these include Mp715, Mp717, GT-MAS:gk, CML176, CML269; CML322, and Tx114 [20,[25][26][27][28]. While stable resistance is a positive advancement in the efforts to breed resistant maize cultivars, all resistant breeding lines identified to date contain tropical germplasm in their backgrounds.…”

Aflatoxin contamination of maize grain is a huge economic and health problem, causing death and increased disease burden in much of the developing world and income loss in the developed world. Despite the gravity of the problem, deployable solutions are still being sought. In the past 15 years, much progress has been made in creating resistant maize inbred lines; mapping of genetic factors associated with resistance; and identifying possible resistance mechanisms. This review highlights this progress, most of which has occurred since the last time a review was published on this topic. Many of the needs highlighted in the last reviews have been addressed, and several solutions, taken together, can now greatly reduce the aflatoxin problem in maize grain. Continued research will soon lead to further solutions, which promise to further reduce and even eliminate the problem completely.

“…The six released germplasm lines were derived from biparental crosses and backcross populations involving tropical elite African inbred lines (1368, 4001, and KU1414-SR) from the IITA [11] with some levels of resistance to aflatoxin production [6] and U.S. inbred lines GT-MAS:gk, MI82, and Mp420, with proven resistance to aflatoxin contamination [2,3,12,13] as parents. TZAR101 was derived from a cross of 1368 to GT-MAS:gk, while TZAR102 and TZAR103 were extracted from a cross of the same tropical inbred line (1368) to MI82.…”

Evaluation of African-Bred Maize Germplasm Lines for Resistance to Aflatoxin Accumulation

et al. 2016

Abstract:Aflatoxins, produced by the fungus Aspergillus flavus, contaminate maize grain and threaten human food and feed safety. Plant resistance is considered the best strategy for reducing aflatoxin accumulation. Six maize germplasm lines, TZAR101-TZAR106, were released by the International Institute of Tropical Agriculture-Southern Regional Research Center (IITA-SRRC) maize breeding collaboration for use in African National Programs and U.S. maize breeding programs. The present investigation was conducted to evaluate aflatoxin reduction by these lines in a U.S. environment. Results demonstrate significant aflatoxin reduction by IITA-SRRC lines in a U.S. aflatoxin-conducive environment (at Mississippi State University). Further testing in different locations and environments is needed to further evaluate the potential usefulness of these germplasm lines.

“…Various approaches have been suggested for genetic control of preharvest aflatoxin contamination including the development and use of crops with resistance to insects, resistance to plant stress (especially for tolerance to drought and high temperatures). Several sources of resistant germplasm were identified and released for crop genetic improvement in corn (McMillian et al, 1993;Williams and Windham, 2001;Naidoo et al, 2002;Guo et al 2007a) and in peanuts (Cole et al, 1995;Holbrook et al, 2000;Guo et al, 2006;Holbrook et al, 2008). Crop resistance to aflatoxin contamination may be achieved by the three strategies: a) resistance to fungal invasion, b) inhibition of aflatoxin formation, and 3) resistance to insects and abiotic stress such as drought.…”

Peanut (Arachis hypogaea L.), or groundnut, is an important crop economically and nutritionally in many tropical and subtropical areas of the world. It is also one of the most susceptible host crops to Aspergillus flavus resulting in aflatoxin contamination. The prevention or elimination of aflatoxin contamination in preharvest and postharvest crops is a serious challenge facing scientists. The recent International Conference on Groundnut Aflatoxin Management and Genomics held in Guangzhou, China, provided an international forum for discussions on the latest accomplishments, the development of strategies, and the initiation of cooperative research for the prevention of aflatoxin contamination. This review summarizes the progress in genetic and genomic research of peanuts and the toxinproducing fungus A. flavus. In particular, the pathway for production and the genetic regulation of afaltoxin, and the peanut-Aspergillus interaction are discussed. The use of a peanut-Aspergillus microarray will help scientists to study the croppathogen interaction; aids in the identification of genes involved in both fungal invasion and crop resistance, and ultimately enhance research to find solutions that prevent aflatoxin contamination in agricultural commodities.
