Signaling crosstalk between ethylene and other molecules

In plants, growth and development are modulated in response to a number of signaling molecules. In past decades, many physiological studies suggested various antagonistic or synergistic effects by multiple signaling molecules in growth regulation of plants. Recent studies have highlighted the machinery for integration of signaling pathways. Here we summarize the findings on molecular mechanisms for crosstalk, focusing on crosstalk between ethylene and other signaling pathways in Arabidopsis.
