Regulation of Barley Architecture by HvAP2-like Transaction Factors

Lead Research Organisation: University of Dundee
Department Name: School of Life Sciences

Abstract

A cereal plant's architecture has a huge impact on how much grain it will produce, and how easily it can be harvested. To meet ever-increasing global grain demand, we must rapidly develop higher-yielding cereal varieties. Our research helps this effort by identifying the genes controlling architectural traits important for yield and revealing their molecular mechanisms using barley as a model system. In this project, we are investigating the function of a group of architectural genes known to control grain number, stem growth and traits associated with resiliency in maize and rice, but about which little is known in barley. We plan to determine the effect of altering each gene's function in barley to reveal the trait(s) controlled by each gene. In addition, we will determine how these genes are regulated and how they interact to control plant architecture and their downstream mechanisms. This research will advance our understanding of the genetic mechanisms underlying cereal plant architecture and link key genes with traits important for yield, acting to inform molecular breeding methods and accelerate the development of higher-yielding crops.

Results and Impact A film was made about how scientist from the University of Dundee use microscopes in their research. One of the four films was about how I use dissection scopes and electron microscopes in my project. This was intended to demonstrate the wide range of uses of microscopes to the general public. The video was on display at the Mills Observatory for six months.
