Abstract:
Polyamine is an important physiological regulation substance functioning in a wide variety of biological processes, such as plant growth, development, senescence and adversity stress tolerance, which widely exist in all living organisms. Their biosynthetic pathways have already been revealed, and their physiological roles are being elucidated gradually. Previous work on polyamines biosynthetic deficiency mutants and various transgenic plants facilitates improved understanding of the important roles of polyamines and biosynthetic enzymes in plant growth and development. This paper summarizes researches in the biosynthetic pathways of polyamines in plants, focusing on research advances on functions of genes involved in polyamine metabolism. In addition, the potential research directions, especially the application of the genes in the genetic engineering of plant stress tolerance were also discussed.
