Genetic control of starch structure and composition in wheat and implications for improving human health

Lead Research Organisation: University of East Anglia
Department Name: Graduate Office

Abstract

Wheat provides approximately one fifth of the calories consumed by humans worldwide, thus improving the nutritional value of wheat grains has potential to make a large impact on human health. Starch composition and structure play a major role in digestibility by humans. However, there is little natural variation in the starch composition of common bread wheat.

In an effort to improve the nutritional quality of foods for human health, this project will focus on understanding the genetic components underlying starch composition and structure in the grain and what consequences this may have for human digestibility. The applied nature of this project will aid in the development of wheat plants with enhanced nutritional value that can be used in food and health studies in Norwich. It will also provide further insight and understanding of starch biosynthesis in wheat and how it may affect plant fitness and potential agronomic quality.

This project will be based upon previous research that has generated valuable genetic and genomic resources in wheat including over 1,500 sequenced TILLING mutants. The student will build a solid skill set in modern plant breeding and trait development. He/she will utilize cutting-edge molecular techniques and bioinformatics approaches to identify and characterize novel alleles regulating starch composition and structure in the grain. The project will also provide applied opportunities for the student to develop and use plant materials in human health related studies. The student will be supervised by a multidisciplinary team across the Norwich Research Park at both the Institute of Food Research and the John Innes Centre.

Description The sbeII wheat previously generated by TILLING was used to develop a range of food products with low digestibility.
The foods developed were used to measure digestibility in vitro and glycaemic response (blood sugar level after a meal) in vivo.
The carbohydrate component of the products developed for the in vivo studies was extensively characterised to identify subtle changes in glycaemic response due to changes in the starch components of the foods, the main nutrient in wheat-based foods.

Overall, some evidence was found of a lower glycaemic response after consumption of sbeII semolina pudding and sbeII white bread compared to the semolina pudding and white bread made from conventional wheat.
Both starch characteristics and food processing were found to have major effects on the degree of digestibility of wheat-based foods.
Exploitation Route This project has shown that the processing applied to crops like wheat to produce foods has a great impact on starch characteristics, end-use quality and digestibility.
The sbeII wheat-based foods have shown potential to elicit a lower glycaemic response in healthy individuals, particularly if used to produce foods that are consumed after one cycle of cooking and cooling, such as deli sandwich bread.

While some evidence of lower glycaemic response after consumption of sbeII bread was found, further studies should investigate the rate and extent of the response, compared to conventional white bread. The use of sbeII wheat in other baked and cooled food products should also be investigated.

Title REST study 
Description REST is about white wheat bread with high Resistant Starch, a type of fibre. Wheat bread made from white flour is one of the UK's favourite foods but normally, it has very low levels of fibre. Fibre exerts a protective role in reducing the risk of many common diseases that are diet related. However, in the UK, 91% of the adult population does not meet the recommended fibre intake of 30g per day. A correct fibre intake helps to control blood sugar levels and body weight, reducing the risk of developing type II diabetes and obesity. We have developed a type of wheat white flour that appears similar to conventional white bread flour but has higher resistant starch content (which is a type of fibre). In this study, we want to measure blood sugar after eating a high resistant starch bread and a conventional white bread, low in resistant starch. This will help us understand if high resistant starch bread can help to boost fibre intake of healthy people. In the long term, we might be able to determine if high resistant starch bread can help reduce the risk of common chronic diseases. We are currently recruiting Healthy volunteers, between 18 and 65 years of age, living within 40 miles from the Norwich Research Park
