IAA has been found to be conjugated to both high- and low-molecular-weight compounds such as,

a) Low-molecular-weight conjugated auxins include esters of IAA with glucose or myo-inositol and amide conjugates such as IAA-N-aspartate

b) High-molecular-weight IAA conjugates include IAAglucan and IAA-glycoproteins found in cereal seeds

c) High-molecular-weight conjugated auxins include esters of IAA with glucose or myo-inositol and amide conjugates such as IAA-N-aspartate

d) Low-molecular-weight IAA conjugates include IAAglucan and IAA-glycoproteins found in cereal seeds
