Summary
It has been clearly demonstrated that some plant species, such as Arabidopsis and tobacco have improved growth and abiotic stress tolerance when a mitochondrial alternative respiratory pathway (AP) mediated by Alternative oxidase (AOX) is more active. This project aims to demonstrate whether there is a link between better growth and yield and more active AOX in in the important grain crop, Hordeum vulgare (barley) under abiotic stress, specifically drought and high light. Two approaches are being taken; an assessment of this pathway in commercially available Barley cultivars displaying varied drought tolerance and the generation of transgenic barley lines over-expressing AOX.
