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

The complete enzyme or holoenzyme in E. coli has a molecular weight of ,460 kD. The holoenzyme (a2bbws) can be separated into two components: the core enzyme (a2bbw) and the sigma factor (the s polypeptide), which is concerned specifically with promoter recognition.
