Ethylene stimulates auxin biosynthesis and basipetal auxin transport toward the elongation zone, where it activates a local auxin response leading to inhibition of cell elongation
I might not understand what information you are looking for, if you could elaborate on what information you are looking for it would help in answering your question. But AUXIN is a single chemical known as Indole Acetic Acid (IAA), AUXINS as a class of plant growth regulator contains a number of other organic acid derivatives of IAA such as IBA, and IPA
I am not 100% sure abut what you are looking for . hOpe the following link might help you out.

In the sentence you provided they stress on "local auxin response" not "local auxin". As auxin responsive factors (ARFs) express in a tissue-specific manner, the "local auxin response" is different for different tissues.
Hi Yang,
1. I found out that your question is copied from the Abstract of this paper below. I read it through to understand the whole content.
2. So, your question: .......auxin transport toward the elongation zone, where it activates a local auxin response leading to inhibition of cell elongation.........., it means that the "auxin response" is happening in the specific area/region ("local"), where is the root elongation zone, and lead to the inhibition of cell elongation.

Ethylene regulates root growth through effects on auxin biosynthesis and transport-dependent auxin distribution. [ http://www.ncbi.nlm.nih.gov/pubmed/17630274 ]
Hi, Yang, auxin is a molecule what is an-equaly distribute in plant organs. And this un-equal distribution is a reason why plant cell even in on organs are different. Tha's why it is very importnat to have information about auxin content and auxin effect in each cell in organs! In your term it may mean local auxin (contents)!
