Biosynthesisofspermidineandspermine
The polyamines spermidine and spermine are expressed in a variety of tissues and are involved in the regulation of apoptosis, cellular proliferation, and progression through the cell cycle. Depletion of polyamines appears to reduce cell growth, and increased polyamine expression is associated with the cancer development and progression, making polyamine biosynthesis a target for the control of cancer. As positively c......閱讀全文

γ氨基丁酸在植物體中多胺降解途徑的介紹
多胺（polyamine，PAs）包括腐胺（putrescine，Put）、精胺（spermine，Spm）和亞精胺（spermidine，Spd），其中以腐胺作為多胺生物代謝的中心物質。多胺降解途徑是指二胺或多胺（PAs）分別經二胺氧化酶（diamine oxidase，DAO）和多胺氧化酶（
多胺對植物鹽誘導的離子流和鹽脅迫具有緩解作用
多胺（PA）是一類生長調節劑，PA的作用多種多樣，包括影響細胞分裂、根的生長、開花和果實的發育，以及細胞凋亡。除此之外，多胺可能作為一個重要的植物脅迫的調節因素起到重要作用，其中一個重要的環境脅迫是鹽脅迫。在脅迫下維持PA的高水平能否提高植物對鹽脅迫的忍耐，這種觀點一直以來存在爭議。澳大利亞的科學家
