Final Report Abstract

This is a multi-disciplinary project that aims to define the epigenomic landscape of wheat. This work is important because wheat is a key global crop, and like many crop species is a hybrid with three distinctive parents. The genomes of these parents interact to generate new traits not found in the genomes of the separate parents. How these new traits arise in wheat is not known. Forming new wheat hybrids is an increasingly important way to improve wheat varieties, as it rapidly increases the range of genetic variation available for selection. Wheat provides an ideal system to understand how new traits arise in hybrids. DNA modifications such as epigenetic modifications are known to influence many aspects gene expression, gene stability and the formation of new gene structures. In this Project we will build a comprehensive view of the wheat epigenome, how it influences chromatin and gene expression, and how it may be re-shaped during the formation of new hybrids. The outcomes of the Project include new understanding to help guide the choice of parents in making new wheat hybrids, understanding how genomes in hybrids interact to influence gene expression and create new traits.
