Interaction with Other Hormones Ethylene does not act in isolation; its function is deeply integrated with other hormonal pathways. In seedlings, it promotes the triple response, which includes shortening of the hypocotyl, thickening of the stem, and exaggeration of the apical hook, helping the seedling push through soil.
Ethylene Function Gene Expression Control and Hormonal Cross-Talk
From seed germination to fruit ripening and response to stress, this simple two-carbon molecule coordinates complex developmental programs that determine crop yield and quality. Cross-talk between ethylene and brassinosteroids or gibberellins fine-tunes growth adjustments, ensuring that developmental decisions balance resource allocation and environmental cues.
ACC is then oxidized by ACC oxidase to yield ethylene, a reaction that requires oxygen and iron. During pathogen invasion, ethylene often works synergistically with jasmonic acid to activate defense genes.
Ethylene Function Gene Expression Control and Hormonal Cross-Talk
In the absence of ethylene, these receptors inhibit a downstream signaling cascade; when ethylene binds, the inhibition is lifted, allowing a signal to propagate that ultimately stabilizes specific transcription factors and alters gene expression. In the nursery industry, it is employed to induce flowering in species like poinsettia and kalanchoe.
