Abstract
Roots of tomato seedlings can be induced to coil by treatment with ethylene. The extent of coiling is dependent on the level of ethylene to which the seedlings are exposed and can be prevented by the incorporation of Ag ions into the growing medium. In contrast to all other tomato mutants examined, roots of the mutant diageotropica do not reorientate their growth in response to ethylene. The results of an agar penetration test indicate that roots of this mutant are agravitropic. The relationship between gravitropism and root coiling, and the origin of the ethylene modified growth pattern is discussed.
