Ethylene regulates many aspects of the plant life cycle, including seed germination, root initiation, flower development, fruit ripening, senescence, and responses to biotic and abiotic stresses. It thus plays a key role in responses to the environment that have a direct bearing on a plant's fitness for adaptation and reproduction. In recent years, there have been major advances in our understanding of the molecular mechanisms regulating ethylene synthesis and action. Screening for mutants of the triple response phenotype of etiolated Arabidopsis seedlings, together with map-based cloning and candidate gene characterization of natural mutants from other plant species, has led to the identification of many new genes for ethylene biosynthesis, signal transduction, and response pathways. The simple chemical nature of ethylene contrasts with its regulatory complexity. This is illustrated by the multiplicity of genes encoding the key ethylene biosynthesis enzymes 1-aminocyclopropane-1-carboxylic acid (ACC) synthase and ACC oxidase, multiple ethylene receptors and signal transduction components, and the complexity of regulatory steps involving signalling relays and control of mRNA and protein synthesis and turnover. In addition, there are extensive interactions with other hormones. This review integrates knowledge from the model plant Arabidopsis and other plant species and focuses on key aspects of recent research on regulatory networks controlling ethylene synthesis and its role in flower development and fruit ripening.

Ethylene Role in Plant Growth, Development and Senescence: Interaction with Other Phytohormones (2017, background): “The exact timing of flowering can be controlled by the plant-environment interaction and endogenous developmental competence of plants to flower, which allows the transition from the vegetative phase to a reproductive phase (Lin et al., 2009).”
Temperature stress and plant sexual reproduction: uncovering the weakest links. (2010, background): “CTR1, ETR1, EIN2) (Lin et al., 2009) are expressed at detectable levels in pollen (Honys and Twell, 2004; Wang et al.”
Interplay between reactive oxygen species and hormones in the control of plant development and stress tolerance. (2015, background): “ET promotes conformational changes in this complex that lead to the release and activation of EIN2, which then regulates the activity of EIN3 and downstream ET responses (Lin et al., 2009).”
