David Holding

David Holding is a Professor in the Department of Agronomy and Horticulture at the University of Nebraska-Lincoln, serving as Associate Department Head and Director of Plant Biology. His research focuses on plant molecular genetics, particularly endosperm development and protein quality improvement in cereals like maize and sorghum.

Key research areas include:

• Elucidating the molecular basis of endosperm hardening in maize kernels
• Characterizing opaque2 modifier genes for Quality Protein Maize development
• Advancing functional genomics platforms in maize and sorghum
• Investigating seed storage proteins and their nutritional impact
• Developing novel popcorn varieties with enhanced protein quality

His methodological approaches integrate transcriptomics, proteomics, metabolic profiling, and genome editing technologies. Current projects aim to identify genetic modifiers for cereal improvement, analyze endosperm mutants, and develop sustainable crop varieties.
