Although there is ample evidence that the inhibition of bud outgrowth by auxin from the shoot apex is linked to stem elongation and highly branched auxin biosynthesis or signaling mutants are dwarf, the third theory proposed in the 1930s, the indirect theory, that explains apical dominance as auxin-induced stem growth indirectly inhibits bud outgrowth has been overlooked. (frontiersin.org)
Since a growing stem is a strong sink for sugars, and sugar is indispensable for shoot branching, the indirect theory of apical dominance might now be explained as auxin-induced stem growth inhibits bud outgrowth by diverting sugars away from buds. (frontiersin.org)
Soon after the discovery that the apical signal that inhibits axillary bud outgrowth is the plant hormone auxin ( Thimann and Skoog, 1933 ), three theories - direct, diversion, and indirect (Figure 1 ) - were proposed to explain the phenomenon of apical dominance (reviewed in Snow, 1937 ). (frontiersin.org)
The direct theory explains apical dominance as auxin synthesized in the shoot apex moves down the stem into buds and inhibits their growth. (frontiersin.org)
According to this theory, apically derived auxin inhibits buds from synthesizing their own auxin necessary for their growth. (frontiersin.org)
The second, diversion, theory of the 1930s explains the phenomenon of apical dominance as auxin from the shoot apex prevents growth promoting factors synthesized in roots and cotyledons from entering into buds and stimulate bud outgrowth. (frontiersin.org)
