Impact of auxin signaling on root colonization of Arabidopsis thaliana by Azospirillum brasilense. KU Leuven
Plant-growth promoting rhizobacteria (PGPR) can directly or indirectly influence growth and development of plants. The best known example of direct plant growth promotion is the bacterial synthesis of plant hormones. The synthesis of auxins in the rhizosphere, with indole-3-acetic acid (IAA) being the most important, leads to stimulation of lateral root formation and root hair development. Recent investigations brought up an entirely new aspect ...
