Transport and Other Modes of Movement of Hormones (Mainly Auxins)

  • Chapter
Book cover Hormonal Regulation of Development II

Part of the book series: Encyclopedia of Plant Physiology ((PLANT,volume 10))

Abstract

In the course of writing this article, it became more and more evident that it would be scarcely possible to review the immense number of studies of translocation of plant hormones since the appearance of the previous Encyclopedia (Leopold 1961). Therefore, instead of aiming at covering all papers and considering all aspects of hormone movement, this review—still numbering more than 500 references—is restricted to three aspects of the topic: first, a brief historical sketch (Sect. 3.2); next, a consideration of the different methods used to estimate translocation and a critical evaluation of each. The section on General Remarks on Hormone Movement (Sect. 3.3), is the main theme of the review and, although there is some disadvantage in scattering results in this section, it is hoped that this is compensated far by illustrating pros and cons as well as advantages and limitations of experimental designs, and overcome by cross-referencing. The third and last section (Evidence of Hormone Translocation, Sect. 3.4) is a brief resume of the results thus far obtained in examining different types of hormone movement and hormone movement systems. Space allows neither a review of the manifold interactions between external and internal factors on hormone translocation, nor an in-depth consideration of the role of hormone distribution and its influence on patterns of growth and development, although they are occasionally referred to in different sections of this survey.
