TLDR
Since 1-MCP apparently is non-toxic at concentrations that are active, it may in future be available for regulating the ripening of fruits and preventing the deleterious effects of ethylene in vegetables.Abstract:
A number of organic molecules that appear to block the ethylene receptor have been discovered recently. For example, on irradiation with visible light, diazocyclopentadiene (DACP), gives rise to some potent but as yet unidentified inhibitor compounds. Some synthetic cyclopropenes have been shown to bind to the ethylene receptor and prevent the physiological action of ethylene for extended periods. Cyclopropene (CP), 1-methylcyclopropene (1-MCP) and 3,3-dimethylcyclopropene (3,3-DMCP) have been shown to prevent ethylene effects in a number of plants. As low a concentration as 0.5 nl l -1 of 1-MCP is sufficient to protect carnation (Dianthus caryophyllus) flowers for several days against ethylene, and 0.7 nl l -1 1-MCP or CP will prevent the ripening of banana (Musa sapientum) for 12 days at 24°C. Some plant organs require higher concentrations of these inhibitors. Complete inhibition of ethylene effects in pea seedlings requires treatment with 40 nl 1 -1 of 1-MCP. These novel inhibitors appear to be suitable for many commercial applications including extending the vase life of cut flowers and the display life of potted plants. Since 1-MCP apparently is non-toxic at concentrations that are active, it may in future be available for regulating the ripening of fruits and preventing the deleterious effects of ethylene in vegetables.read more

1-Methylcyclopropene: a review
TL;DR: In this article, a review of the use of 1-methylcyclopropene (1-MCP) as an inhibitor of ethylene action is presented, which is a tool that can help scientists make major advances in understanding the role of the chemical in plants.

Ethylene-induced stomatal closure in Arabidopsis occurs via AtrbohF-mediated hydrogen peroxide synthesis
Radhika Desikan,Rhian Harrett-Williams,Cecilia Tagliavia,Klaus Harter,Richard Hooley,John T. Hancock,Steven J. Neill +6 more
TL;DR: The data indicate that ethylene and H(2)O( 2) signalling in guard cells are mediated by ETR1 via EIN2 and ARR2-dependent pathway(s), and identify AtrbohF as a key mediator of stomatal responses to ethylene.

Promotion of plant growth by ACC deaminase-producing soil bacteria
TL;DR: In this article, the physiological basis for plant growth-promotion effect is examined in some detail, and models are presented that endeavour to explain the seemingly paradoxical effects of ethylene on a plant's response to stress, how the expression of this enzyme is transcriptionally regulated in many bacterial strains and how ACC deaminase-containing plant growthpromoting bacteria alter plant gene expression and positively modulate plant growth.

The use of 1-methylcyclopropene (1-MCP) on fruits and vegetables.
TL;DR: The recent availability of the inhibitor of ethylene perception, 1-methylcyclopropene (1-MCP), has resulted in an explosion of research on its effects on fruits and vegetables, both as a tool to further investigate the role of Ethylene in ripening and senescence, and as a commercial technology to improve maintenance of product quality.

Ethylene and fruit ripening
TL;DR: Evidence suggesting that the NR ethylene perception and transduction pathway is specific to a defined set of genes expressed in ripening climacteric fruit and that a distinct ETR pathway regulates other ethylene-regulated genes in both immature and ripening Climacteric Fruit as well as in non-climacteric fruits is discussed.

A potent inhibitor of ethylene action in plants.
TL;DR: Ag(I), applied foliarly as AgNO(3), effectively blocked the ability of exogenously applied ethylene to elicit the classical "triple" response in intact etiolated peas and should prove useful in defining further the role of ethylene in plant growth.

Ethylene-Binding Sites Generated in Yeast Expressing the Arabidopsis ETR1 Gene
TL;DR: It was concluded that ETR1 acts as an ethylene receptor in Arabidopsis and that the amino-terminal hydrophobic domain of the protein is the site of ethylene binding.

Molecular Requirements for the Biological Activity of Ethylene
Stanley P. Burg,Ellen A. Burg +1 more
TL;DR: The molecular requirements for ethylene action were investigated using the pea straight growth test and it is suggested that CO(2) delays fruit ripening by displacing the ripening hormone, ethylene, from its receptor site.

Effect of 1-methylcyclopropene and methylenecyclopropane on ethylene binding and ethylene action on cut carnations
TL;DR: Most of the natural increase in ethylene production during senescence is prevented by treatment with 1-MCP, and a closely related compound, methylenecyclopropane shows ethylene activity.

Novel Gaseous Ethylene Binding Inhibitor Prevents Ethylene Effects in Potted Flowering Plants
TL;DR: In this paper, a 6-hour fumigation of flowering Begonia ×elatior hybrida Fotsch. 'Victory Parade' plants with 1-methylcyclopropene (1-MCP), a gaseous nonreversible ethylene binding inhibitor, strongly inhibited exogenous ethylene effects such as bud and flower drop, leaf abscission, and accelerated flower senescence.
