Research Interests

 

We are currently leading a large collaborative effort aimed to assemble a high quality reference genome for wild emmer wheat (AABB genome). Go to our website here

 

The Distelfeld laboratory is focused on improving yield and quality of crop plants, especially wheat, with an emphasis on physiological processes that occur during plant senescence. We believe that an integrated system approach, combining physiological, genetic, genomic and transgenic tools, is required to dissect complex traits and reduce the gap between phenotype and genotype. Our approach is implemented by the combination of laboratory and field experiments.  Our specific research areas include:

  • Wheat genetics and genomics
  • Plant breeding
  • Gene-network controlling senescence in wheat senescence
  • Molecular mechanisms controlling grain yield in Wheat senescence
  • Flowering time in wheat

 

It is widely accepted that future agriculture will face the challenge of increasing productivity under limited resources. This will require the development of better yielding crops together with resistance to biotic and abiotic stresses. New genomic technologies offer a great potential to advance our understanding of plant physiological processes and accelerate the exploitation of beneficial traits from wild germplasm.
