Chloroplasts, Compartmental Analysis, Indole-3-acetic Acid (LAA), IAA Conjugation, Permeability A compartmental analysis of the distribution of the plant hormone indole-3-acetic acid (IAA) was performed with mesophyll cells of spinach leaves. The results indicated that up to about 45% of the total amount of free IAA in the laminae of spinach is localized within the chloroplasts, although these ...
