“…Gaseous at life's temperature, it is involved in monitoring and triggering growth transitions such as fruit ripening, seed germination, wound healing and shedding of aged leaves, and this can work at a distance. Its presence, first established in 1934 by Richard Gane from an emanation of ripening fruits (for a discussion see Bakshi et al, 2015), was subsequently shown to be of physiological significance by a variety of authors (Schuman and Baldwin, 2018 and see Pratt et al, 1948 for early experiments). As expected, this observation of considerable biotechnological importance triggered research to uncover ethylene biosynthesis pathways.…”

SummaryMethionine is essential for life. Its chemistry makes it fragile in the presence of oxygen. Aerobic living organisms have selected a salvage pathway (the MSP) that uses dioxygen to regenerate methionine, associated to a ratchet‐like step that prevents methionine back degradation. Here, we describe the variation on this theme, developed across the tree of life. Oxygen appeared long after life had developed on Earth. The canonical MSP evolved from ancestors that used both predecessors of ribulose bisphosphate carboxylase oxygenase (RuBisCO) and methanethiol in intermediate steps. We document how these likely promiscuous pathways were also used to metabolize the omnipresent by‐products of S‐adenosylmethionine radical enzymes as well as the aromatic and isoprene skeleton of quinone electron acceptors.

“…Decades of dedicated research revealed a myriad of plant responses to ethylene (Abeles et al, 1992). This two-carbon atom molecule controls several processes linked to vegetative plant growth but is also a major player in seed germination, fruit ripening, leaf and flower senescence and abscission (Lin et al, 2009; Bakshi et al, 2015). During the above-mentioned processes ethylene production increases significantly in comparison to the relatively low basic levels.…”

1-aminocyclopropane-1-carboxylic acid (ACC) is a non-protein amino acid acting as the direct precursor of ethylene, a plant hormone regulating a wide variety of vegetative and developmental processes. ACC is the central molecule of ethylene biosynthesis. The rate of ACC formation differs in response to developmental, hormonal and environmental cues. ACC can be conjugated to three derivatives, metabolized in planta or by rhizobacteria using ACC deaminase, and is transported throughout the plant over short and long distances, remotely leading to ethylene responses. This review highlights some recent advances related to ACC. These include the regulation of ACC synthesis, conjugation and deamination, evidence for a role of ACC as an ethylene-independent signal, short and long range ACC transport, and the identification of a first ACC transporter. Although unraveling the complex mechanism of ACC transport is in its infancy, new questions emerge together with the identification of a first transporter. In the light of the future quest for additional ACC transporters, this review presents perspectives of the novel findings and includes considerations for future research toward applications in agronomy.

“…The abscission process has been described as having four stages (Patterson, 2001;Taylor and Whitelaw, 2001;Roberts et al, 2002;Kim, 2014) Ethylene was discovered as a gaseous plant hormone associated with organ abscission following its identification as the active component in illuminating gas, which caused leaf abscission in trees growing along urban streets (Abeles et al, 1992;Bakshi et al, 2015;Chang, 2016). Hall (1952) suggested that auxin and ethylene together play a role in the timing of leaf abscission.…”

Number of figures: 1 Word count: Re-evaluation of the ethylene-dependent and-independent pathways in the regulation of organ abscission focusing on model plants of flower abscission Highlights: Ethylene is the key regulator of organ abscission, while the IDA-HAE-HSL2 pathway acts downstream of ethylene signaling. The involvement of the turgor pressure in the execution of abscission is suggested. .
