Plant breeding has been enormously successful at increasing crop yields over the course of the 20th century, but further progress that would meet increasing demands for food, fuel, and fiber is threatened by global climate change. Because yield is an environmentally-dependent ph…

This Project identified the relationships between storage conditions, dry matter losses (DMLs) caused by Fusarium species in cereal grains and mycotoxin contamination and assessed novel control strategies for post-harvest grain management including chemical control and ozone. F.…
Sustainable agriculture in China is highly threatened by rapid urbanization, land degradation and high population pressure. Yunnan Province, south-west China, is 94% mountainous and lacks flat land. Food shortages and inappropriate cultivation have led to intensive cultivation o…
Scientists face an unprecedented challenge of increasing food production by 100% within the next fifty years to meet demand while responding to the undetermined effect and impact of climate change. To respond to these challenges, scientists are turning to models to assist them i…
Detecting stress in plants resulting from different stressors including nitrogen deficiency, salinity, moisture, contamination and diseases, is crucial in crop production. In the Nile Valley, crop production is hindered perhaps more fundamentally by issues of water supply and sa…
Genetic diversity in the head smut pathogen Sporisorium reilianum was assessed using anonymous RFLP loci in the genomic DNA of isolates sampled from two different hosts in several regions of the world. Southern hybridizations to 473 anonymous random probes detected a high level …
Plant genomes have the capacity to change in response to abiotic stress and other environmental signals. In maize (Zea mays L.), enhanced genetic recombination in response to low temperature has been shown to alter recombination frequencies in maize (Shams-UI-Islam, 1956). The e…
Given high population growth rates, subsistence, low-input agriculture, and consequent low and stagnant incomes, a challenge for economists and development practitioners in Sub-Saharan Africa is to identify sustainable models of input intensification to promote agricultural prod…
Cropping systems are composed of a set of crops and their attendant management practices. Addition or removal of a crop from a cropping sequence results in both biophysical and managerial changes, creating complex interactions that can be difficult to study. Long-term field expe…
Genomic structural variants (SV) have a significant impact on phenotypic differences. Characterization of such variants can provide insights into genomic evolution and reveal population dynamics. However, our understanding of structural variants is limited by technical and metho…
