Starch is a key carbon and energy reserve that underpins plant growth. This in turn underpins much of Australia's $60 billion agriculture industry. Starch also provides most of the calories in the human diet and is a renewable commodity supporting manufacturing industries. Dependence of society on starch will increase as it becomes used more for novel materials and for bio-ethanol production, which in turn will create new jobs in the rural economy. A major quality problem in cereal grain is pre-harvest starch breakdown caused by warm wet weather triggering events associated with germination. By understanding starch metabolism in plants we will be better able to manage and enhance growth of crop plants, starch production and seed quality.

淀粉是支撑植物生长的关键碳和能量储备。这反过来又支撑了澳大利亚600亿美元农业的大部分。淀粉还提供了人类饮食中的大部分卡路里，并且是支持制造业的可再生商品。随着淀粉更多地用于新材料和生物乙醇生产，社会对淀粉的依赖将增加，这反过来又将在农村经济中创造新的就业机会。谷物中的一个主要质量问题是由温暖潮湿的天气引发与发芽相关的事件引起的收获前淀粉分解。通过了解植物中的淀粉代谢，我们将能够更好地管理和提高作物的生长，淀粉生产和种子质量。
