WebAuxin has a central role in determining tomato fruit growth and development, and most of its action is mediated by gibberellins (GAs). The diageotropica (dgt) mutant of tomato … WebThe morphological effects of gibberellin A3 (GA3) on the dgt mutant of tomato were investigated. The mutant effectively showed the normal range of responses, including a promotion of stem length due to an increased number of longer internodes, a dramatic increase in apical dominance, and effects on leaf shape and colour.
