Ecotypes, individuals of a species that vary in external appearance and their variations are genetically fixed and irreversible The individuals of a species growing under different environmental conditions differ in external appearance, but these changes are only temporary, not permanent, and hence reversible Ecads (Ecophenes).

ABRE PyACGTGGC & coupling element (CE) is a major cis‐acting element in ABA responsive gene expression. 

The basic leucine zipper (bZIP) transcription factors AREB and ABF can bind to the ABRE cisacting element to activate ABA‐dependent gene expression

Auxin transport takes place polarly

Main axes of shoots and roots have apex-base structural polarity

This structural polarity is dependent on the polarity of auxin transport

Went discovered that IAA moves mainly from the apical to basal end

This type of unidirectional transport is termed polar transport
