Abstract

Wheat and barley are the major temperate cereals, being used for food, feed and industrial raw material. However, in all cases the quality may be limited by the amount, composition and properties of the grain storage proteins. We describe how a combination of biochemical and molecular studies has led to an understanding of the molecular basis for breadmaking quality in wheat and feed quality in barley, and also provided genes encoding key proteins that determine quality. The control of expression of these genes has been studied in transgenic tobacco plants and by transient expression in cereal protoplasts, providing the basis for the production of transgenic cereals with improved quality characteristics.

摘要

小麦和大麦是主要的温带谷类作物，用于食品、饲料和工业原料。然而，在所有情况下，其品质可能会受到谷物贮藏蛋白的数量、组成和特性的限制。我们描述了生化和分子研究相结合如何使人们了解小麦面包制作品质和大麦饲料品质的分子基础，并且还提供了编码决定品质的关键蛋白的基因。这些基因的表达调控已在转基因烟草植株中进行了研究，并通过在谷类原生质体中的瞬时表达进行了研究，为培育具有改良品质特性的转基因谷类作物奠定了基础。
