Gravity Perception and Response Mechanism in Graviresponding Cereal Grass Shoots

Chapter
Part of the Advances in Agricultural Biotechnology book series (AABI, volume 21)

Abstract

The gravitropic response involves three components: (1) gravity perception, (2) transduction, and (3) asymmetric growth response. We have already reported recently (in this series edited by S. S. Purohit) on the transduction phase, that is, the stage when hormones (IAA, GAs and their conjugates) become asymmetrically distributed and bring about asymmetric growth in gravistimulated cereal grass leaf-sheath pulvini (Kaufman and Dayanandan, 1984). In this review, we shall focus on the most recent information available on what is known about the first and third components of response, namely, gravity perception and the mechanism of asymmetric growth in upward bending cereal grass leaf-sheath pulvini.
