“…The vegetative development of plants is strongly dependent on the action of ethylene which has a close and reciprocal relation with auxin, another major determinant of plant architecture (Vandenbussche et al 2012). During vegetative development, differential ACO gene expression has been observed in mung bean (Kim and Yang 1994), tomato (Barry et al 1996;Moeder et al 2002), sunflower (Liu et al 1997), potato (Nie et al 2002), and tulip (Momonoi et al 2007) tissues.…”

“…It is generally accepted that all plant organs are capable of synthesizing ethylene from ACC, however, some data clearly imply that the contribution of different cell types within an organ or tissue is not equal (Vandenbussche et al 2012). In the root of Arabidopsis for example, at least one member of the ACS family is expressed in each cell type, whereas the expression of the known ACO genes does not cover all root cell types (Dugardeyn et al 2008;Vandenbussche et al 2012).…”

Regulation of ethylene biosynthesis at the level of 1-aminocyclopropane-1-carboxylate oxidase (ACO) gene

2012

Ethylene, a gaseous plant hormone regulates essentially all physiological processes during the plant's life cycle. The practical implications of ethylene biosynthesis regulation for plant improvement have supported the continuous basic research on dissecting the structure of genes encoding ethylene biosynthetic enzymes, their differential expression patterns, and mechanisms underlying their transcriptional activity. ACC oxidase (ACO) is involved in the final step of ethylene production in plant tissues. In various plants several ACO isoforms have been isolated which are encoded by a multigenic family. There is a strong evidence that ACO gene expression is positively correlated to the ethylene production rates and its multiple isoforms are under development and environmental control. Thus, the regulation of ACO gene activity may act either as an additional or in several cases also as a main level for controlling ethylene biosynthesis in higher plants. This review summarizes in detail the knowledge about organization and gene structure, and transcriptional expression of ACO genes from different plant species. The perspectives of manipulating ACO gene as a method in biotechnological modification of ethylene synthesis are also discussed.

“…Ethylene controls many features of plant growth and development from seed germination through the root and stem formation to fruit ripening and is a key mediator of stress responses in plants (Merchante et al 2013). It controls plant development and growth by regulating the meristem activity and cell-wall structure (Vandenbussche et al 2012). Among these functions of ethylene is the regulation of 'Rhizobium'-induced nodulation in legumes (Gresshoff et al 2009), a process that is, in some way, similar to gall formation.…”

Plant development reprogramming by cynipid gall wasp: proteomic analysis

et al. 2017

An insect-plant interaction induced gall formation is where gall wasps change the plant development towards formation of new units to shield and nourish the evolving larvae. The targets of the insect signals and the mechanism of gall development are unknown. To show the molecular pathways that are responsive to the gall wasp, the proteomic approach was used to compare the gall with non-gall plant tissues. We studied three oak gall species (Cynips quercusfolii, Cynips longiventris, and Neuroterus quercusbaccarum) and the host plant (Quercus robur). Among the 21 identified proteins, 18 increased and three decreased in abundance in gall tissue, in comparison to the leaf tissues. Ten proteins were C. quercusfolii responsive, two only with this gall inducer, while seven increased in abundance. Eleven proteins were C. longiventris responsive, and two only with this gall inducer. Sixteen proteins were associated with gall formation by the N. quercusbaccarum and, in this, eight only with this gall inducer. A similar effect on protein abundance occurred as galls in leaf veins (for five proteins). For leaf blades, such a relation was not found. The role of each protein is discussed according to its involvement in the gall formation. Moreover, S-adenosyl methionine synthase, flavone 3-hydroxylase, stress-and pathogenesis-related proteins, and gamma carbonic anhydrase are associated with developmental regulation of plant tissue into a gall.

“…Biosynthetic capacity for ethylene production may be nearly ubiquitous throughout the plant body, but biosynthesis is generally maintained at low levels by regulatory circuitry that confers tight control while allowing rapid and dramatic increases under conditions such as wounding or fruit ripening (Vandenbussche et al, 2012). Ethylene biosynthesis levels change in response to endogenous developmental cues as well as exogenous signals including light, abiotic stress, and pathogens (for review, see De Paepe and Van der Straeten, 2005;Argueso et al, 2007;Lin et al, 2009;Rodrigues et al, 2014), and it is clear that both transcriptional and posttranslational mechanisms provide strict control of biosynthetic enzyme activity levels.…”

Strictly controlled production of ethylene gas lies upstream of the signaling activities of this crucial regulator throughout the plant life cycle. Although the biosynthetic pathway is enzymatically simple, the regulatory circuits that modulate signal production are fine tuned to allow integration of responses to environmental and intrinsic cues. Recently identified posttranslational mechanisms that control ethylene production converge on one family of biosynthetic enzymes and overlay several independent reversible phosphorylation events and distinct mediators of ubiquitin-dependent protein degradation. Although the core pathway is conserved throughout seed plants, these posttranslational regulatory mechanisms may represent evolutionarily recent innovations. The evolutionary origins of the pathway and its regulators are not yet clear; outside the seed plants, numerous biochemical and phylogenetic questions remain to be addressed.
