Auxin - Gibberellin Interaction in Apical Dominance " 2
Indoleacetic acid and gibberellic acid were added to decapitated lightgrown 'Alaska' pea seedlings as substitutes for the intact apex in the control of apical dotiinance. Of various concentrations and combinations tried, a conrbintation of 1 % indoleacetic acid 1 % gibberellic acid was the most inihibiting to side bud growth. The greatest degree of hormonally induced side bud inhibition was ach...

متن کاملGibberellin-auxin interaction in pea stem elongation.
Joint application of gibberellic acid and indole-3-acetic acid to excised stem sections, terminal cuttings, and decapitated plants of a green dwarf pea results in a markedly synergistic growth response to these hormones. Synergism in green tall pea stem sections is comparatively small, although growth is kinetically indistinguishable from similarly treated dwarf sections.Gibberellin-induced gro...
متن کاملAuxin acts in xylem-associated or medullary cells to mediate apical dominance.
A role for auxin in the regulation of shoot branching was described originally in the Thimann and Skoog model, which proposes that apically derived auxin is transported basipetally directly into the axillary buds, where it inhibits their growth. Subsequent observations in several species have shown that auxin does not enter axillary buds directly. We have found similar results in Arabidopsis. G...
متن کاملCrosstalk of arabinogalactan protein, auxin, gibberellin, and callose in Al-treated Tea seedlings
Arabinogalactan proteins (AGP) are a class of cell surface plant peptidoglycans which have been implicated in root elongation and signal transduction pathways. AGPs function not only as markers of cellular identity but also as signaling molecules, which might initiate signal transduction. Aluminum promotes the elongation of tea (Camellia sinensis L.) roots. Although some mechanisms by which Al ...
