Agricultural productivity is particularly sensitive to environmental alteration, especially at the growth margins where temperature extremes and water availability already limit growth and yield. Predicted losses in tillable land due to global climate change and anticipated population increases in coming decades will place ever greater demands on agricultural systems to meet the increasing demands for food, forage, and bioenergy based resources. Addressing this demand will necessitate expansion of crop adaptation for cultivation in marginal environments using sustainable and low-input agronomic practices.
This special issue of Agronomy focuses on the application of innovations in omics-based research (genomics, proteomics, metabolomics, phenomics, etc ) to the genetic improvement of domesticated crop plants adapted for enhanced growth and yield under changing environmental pressures resulting from rapid and dramatic alterations in global weather patterns. Papers are sought that discuss how enhanced agro-ecological adaptation of plants to abiotic and biotic stress can be achieved using novel and emerging technologies and providing frameworks for sustainable agricultural production in the face of environmental uncertainty.

Abstract : Global climate change is affecting crop performance. Fluctuation in spring temperatures can have a negative outcome for germination efficiency and ultimately crop yield in susceptible varieties; defining the genetic and physiological bases for germination efficiency under cooler than expected temperatures is a useful goal. We are using genome wide association studies to analyze germination efficiency in a well-characterized panel of diverse maize inbred varieties. In parallel, we have used non-targeted mass spectrometry paired with network analysis to characterize the maize grain metabolome. We combine physiological and metabolomic phenotyping within a statistical genomics framework to identify potential key factors for germination efficiency under optimal and sub-optimal temperatures.

- African agriculture challenge by strong environmental changes and a growing populations
- A untapped functional diversity exist in African crops (millet, sorghum and fonio)
- Crop functional diversity might be useful to cope to changing climate (example pearl millet in Niger) and feed a growing populations (fonio as diversification)
- Wild relative diversity interesting because wild relatives grows in drier environment (ex: pearl millet and sorghum)
- Next generation sequencing approaches offers new tool to unlock functional genetic diversity
- Inventory/example of NGS approach and their uses
- Genome wide association mapping and genome wide selection scan offer opportunity to identify agronomic QTLs
- Explanation of association mapping, its interest and new recent development
- Explanation of selection scan approaches, their interest and recent development
- Combining association mapping and selection scan (examples)
