Indoleacetic acid cytokinins

Plant hormone analysis tends to be a very difficult task due in part to the low levels that occur naturally. Over the past several years Weiler and his coworkers and a number of other groups have developed extremely sensitive immunoassays for many of the natural plant hormones ( ). These assays have greatly reduced the time and effort required to analyze indoleacetic acid, cytokinins, gibberellins, and abscisic acid. [Pg.248]

In animals hormones are produced either in special glands (cf. Table 64) or are formed in tissues in which the production of hormones is a biochemical side activity only (so-called tissue hormones). In plants and microorganisms, special hormone-producing glands are absent, but also in plants hormone synthesis is unequal in the different types of cells. Cytokinins, for instance, are produced predominantly in roots and 3-indoleacetic acid in apical meristems. [Pg.498]
