天然脱落酸((+)-Abscisic acid, S-ABA〕是一种具有倍半萜羧酸结构的植物天然生长调节物质,是植物体的“抗逆免疫因子”。1963年美国艾迪科特等从棉铃中提纯了一种物质能显著促进棉苗外植体叶柄脱落,称为脱落素II。英国韦尔林等也从短日照条件下的槭树叶片提纯一种物质,能控制落叶树木的休眠,称为休眠素。1965年证实,脱落素II和休眠素为同一种物质,统一命名为脱落酸。 脱落酸在衰老的叶片组织、成熟的果实、种子及茎、根部等许多部位形成。水分亏缺可以促进脱落酸形成。脱落酸在植物体内才再 (+)-Abscisic acid is a plant hormone and growth regulator involved in several physiological mechanisms including seed dormancy, leaf abscission, stomatal movement, and plant stress responses such as drought. Abscisic acid has been used in a study to learn about expression analysis of four peroxiredoxin genes from Tamarix hispida.
