The auxin-resistant diageotropica mutant of tomato responds to gravity via an auxin-mediated pathway.

Planta - 1 May 2000

Rice M S, Lomax T L

Abstract excerpt

Hypocotyls of the diageotropica (dgt) mutant of tomato (Lycopersicon esculentum Mill.) do not elongate in response to exogenous auxin, but can respond to gravity. This appears paradoxical in light of the Cholodny-Went hypothesis, which states that shoot gravicurvature results from asymmetric stimulation of elongation by auxin. While light-grown dgt seedlings can achieve correct gravitropic reorientation, the...
