Abstract:
Gravitropism is a classical subject in plant physiology. However, the molecular mechanisms that regulate gravitropism are unknown. Recently, many gravitropic mutants have been isolated from Arabidopsis thaliana and several genes for gravitropism have been cloned and characterized. These studies have shown that (1) the endodermis is essential for shoot gravitropism and (2) an auxin transport system and signaling pathway are necessary for gravitropism. Recent studies in Arabidopsis are reviewed and genetic regulation of gravitropism in this organism is discussed.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
