Promotion of Xyloglucan Metabolism by Acid pH 1

PMCID: PMC541826  PMID: 16659306

Abstract

Like indoleacetic acid, buffers of acidic pH, which stimulate elongation of pea (Pisum sativum var. Alaska) stem tissue, induce the appearance within the tissue of a watersoluble xyloglucan polymer that probably arises from previously deposited wall material. Neutral pH buffers, which inhibit the elongation response to indoleacetic acid in this tissue, inhibit indoleacetic acid-induced increase in soluble xyloglucan. The findings provide further evidence that release of soluble xyloglucan from the cell walls of pea results from the biochemical action on the cell wall that is responsible for wall extension. The data also indicate that treatment of tissue with either auxin or acidic pH has a similar biochemical effect on the cell wall. This is consistent with the H+ secretion theory of auxin action.
