Application

3-Indoleacetic acid has been used:
  • as standard to quantify hormones
  • to modify MS (Murashige and Skoog) media for the initiation of callus
  • as an external standard in the analyses of free endogenous growth regulators

Indole-3-acetic acid (IAA) is a natural phytohormone (plant auxin) used as a supplement in media such as Murashige and Skoog media and Gamborg′s B5 media. IAA is a plant signaling molecule involved in plant organogenesis and growth control.

Macroautophagy (hereafter autophagy) is a well-conserved cellular process through which cytoplasmic components are delivered to the vacuole/lysosome for degradation and recycling. Studies have revealed the molecular mechanism of transcriptional regulation of autophagy-related (ATG) genes upon nutrient deprivation. However, little is...
