ABSTRACT Structural components of second messenger signaling (nucleotides and associated enzyme systems) within plant and animal cells have more in common than the hormones that initiate metabolic and functional changes. Neurotransmitters and hormones of mammalian pharmacologic classes relate to purine nucleotides in respect of chemical structure and the molecular changes they initiate. This study compares the molecular structures of purine nucleotides with compounds from the abscisic acid, auxin, brassinosteroid, cytokinin, gibberellin, and jasmonate classes by means of a computational program. The results illustrate how phytohomones relate to each other through the structures of nucleotides and cyclic nucleotides. Molecular similarity within the phytohormone structures relates to synergism, antagonism and the modulation of nucleotide function that regulates germination and plant development. As with the molecular evolution of mammalian hormones, cell signaling and cross-talk within the phytohormone classes is purine nucleotide centered.

植物激素:与嘌呤核苷酸和一些药物的结构和功能关系

摘要 植物和动物细胞内第二信使信号(核苷酸和相关酶系统)的结构成分比启动代谢和功能变化的激素有更多的共同点。哺乳动物药理学类别的神经递质和激素在化学结构和它们引发的分子变化方面与嘌呤核苷酸有关。本研究通过计算程序比较了嘌呤核苷酸与脱落酸、生长素、油菜素甾体、细胞分裂素、赤霉素和茉莉酸类化合物的分子结构。结果说明了植物激素如何通过核苷酸和环核苷酸的结构相互关联。植物激素结构内的分子相似性与协同作用有关,拮抗作用和调节发芽和植物发育的核苷酸功能。与哺乳动物激素的分子进化一样,植物激素类别中的细胞信号传导和串扰以嘌呤核苷酸为中心。
