Plants and algae use light energy to fix atmospheric carbon dioxide into sugars by way of a complex series of reactions in the chloroplast collectively called photosynthesis. These sugars act as the cellular fuel, ultimately driving metabolic processes that allow plants and algae to grow, develop and reproduce. These sugars are often produced in excess and are used at times when energy generation capabilities are at a minimum, such as in the evening or in the seed of a flowering plant. Under such conditions, the sugars can be stored as complex carbohydrates, which in plants and many algae is starch. Starch granules function as cellular energy reserves and may shrink or swell in size according to the energy demands of the cell. Starch and related polysaccharides are the most abundant, naturally occurring and renewable substances and as such, are integral to the growth and sustenance of many complex life forms. The enzymatic processes responsible for starch preservation from pathogenic exploitation remain largely unknown. An understanding of starch regulation is of utmost importance both as an emerging resource for biofuels as well as the industries that rely heavily on starch as a raw material.

植物和藻类利用光能通过叶绿体中一系列复杂的反应将大气中的二氧化碳固定为糖，这些反应统称为光合作用。这些糖作为细胞燃料，最终驱动代谢过程，使植物和藻类生长，发育和繁殖。这些糖通常过量产生，并且在能量产生能力最低时使用，例如在晚上或开花植物的种子中。在这种条件下，糖可以作为复杂的碳水化合物储存，在植物和许多藻类中是淀粉。淀粉颗粒作为细胞的能量储备，并可根据细胞的能量需求收缩或膨胀。淀粉和相关多糖是最丰富的、天然存在的和可再生的物质，因此，对于许多复杂生命形式的生长和维持是不可或缺的。负责淀粉保存病原体开发的酶过程仍然在很大程度上是未知的。 了解淀粉监管是至关重要的，无论是作为一种新兴的生物燃料资源，以及严重依赖淀粉作为原材料的行业。
