种子在发育中积累了为其萌发和幼苗早期生长所需要的大量贮藏产物或转化产物。能量的转化包括有复合碳水化合物(淀粉)和各种液体;而N、C 和S 的转化则是积累于特定的各种贮藏蛋白中。各种碳水化合物和液体的合成涉及各种复杂的代谢过程,而人们对这些有关代谢通路已了解得很清楚,这将有助于通过遗传工程技术改良和提高种子的质量。通过遗传工程而直接提高种子质量主要要涉及到种子蛋白的
Seeds accumulate during development in large quantities of stored or transformed products needed for their germination and early seedling growth. Energy conversion includes complex carbohydrates (starch) and various liquids; and N, C and S are accumulated in a variety of specific storage protein. The synthesis of various carbohydrates and liquids involves a variety of complex metabolic processes, and understanding of these metabolic pathways is well understood and will help improve and enhance the quality of the seeds through genetic engineering. Direct improvement of seed quality through genetic engineering involves mainly seed proteins
