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......阅读全文

γ氨基丁酸在植物体中多胺降解途径的介绍
多胺（polyamine，PAs）包括腐胺（putrescine，Put）、精胺（spermine，Spm）和亚精胺（spermidine，Spd），其中以腐胺作为多胺生物代谢的中心物质。多胺降解途径是指二胺或多胺（PAs）分别经二胺氧化酶（diamine oxidase，DAO）和多胺氧化酶（
多胺对植物盐诱导的离子流和盐胁迫具有缓解作用
多胺（PA）是一类生长调节剂，PA的作用多种多样，包括影响细胞分裂、根的生长、开花和果实的发育，以及细胞凋亡。除此之外，多胺可能作为一个重要的植物胁迫的调节因素起到重要作用，其中一个重要的环境胁迫是盐胁迫。在胁迫下维持PA的高水平能否提高植物对盐胁迫的忍耐，这种观点一直以来存在争议。澳大利亚的科学家
