應用

(+)-Abscisic acid has been used:
  • as a supplement for the germination of Arabidopsis thaliana seeds
  • as a component of buffered nodulation medium to check its effects on lateral root density (LRD) in leguminous and non-leguminous plants
  • as a standard to study its effects on root meristem defects in Medicago truncatula latd mutant

生化/生理作用

植物激素和生长调节剂,参与多种生理机制,包括种子休眠、叶片脱落、气孔运动和植物胁迫反应。 通过与数种细胞内信号转导系统的复杂相互作用,它可以调控数百种植物基因的表达。

其他說明

Natural isomer of the abscission-accelerating plant hormone.

The LATD gene of the model legume, Medicago truncatula, is required for the normal function of three meristems, i.e. the primary root, lateral roots and nitrogen-fixing nodules. In latd mutants, primary root growth eventually arrests, resulting in a disorganized root

The phytohormone abscisic acid (ABA) plays a crucial role in adaptive responses to environmental stresses, such as drought and high salinity, as well as in plant development, such as seed maturation and dormancy. PYR/PYL/RCAR has been identified as a bona

Legumes are unique among higher plants in forming a symbiosis with Rhizobium. Phylogenetic studies indicate this symbiosis may have evolved as many as three times within the Fabaceae; alternatively, a predisposition for nodulation evolved early in the history of the
