“…germanica. The toxicity of ethanol to plant tissues has been questioned in a detailed review of this subject by Jackson, Herman and Goodenough (1982). However, in these studies the conclusions were based either on the effects of ethanol given under aerobic conditions or else to seedlings where even though the root medium was anaerobic there was ready access to oxygen by diffusion from the shoot.…”

Fermentation Rates and Ethanol Accumulation in Relation to Flooding Tolerance in Rhizomes of Monocotyledonous Species

1984

Fermentation capacity as measured by alcohol dehydrogenase (ADH) and lactate dehydrogenase (LDH) activity were estimated together with ethanol and lactate accumulation over a period of 15 d anoxia in rhizomes of six monocotyledonous species. With the exception of Iris germanica all the species were characteristic wetland plants.Under anoxia an accumulation of ethanol took place in all species. Lactic fermentation was found to be of less importance in every case. The amount of ethanol accumulated depended on the ability of the rhizome to eliminate it from its tissues. Despite great variations in fermentative capacity as seen in the ADH measurements the wetland species did not accumulate ethanol to concentrations greater than 30 /imol g~' fresh weight. This represented a plateau above which the ethanol concentration did not rise even with continued anaerobic incubation. No such plateau of ethanol accumulation was found in the dryland species Iris germanica which accumulated ethanol steadily reaching concentrations of 70/imol g"' fresh weight.If ethanol is toxic to higher plant tissues then the steady state condition of low ethanol accumulation found in wetland species will minimize this danger.

“…Ethanol production in plants/fruits Ethanol production (through anaerobic metabolism) generally results from low concentrations of O 2 which can either be caused by reduced levels of external O 2 or due to enhanced resistance to the diffusion of O 2 into the plant parts/fruits (Jackson et al 1982). Fruits undergoing the developmental/ripening process exhibit changes in the levels of O 2 and CO 2 inside them.…”

Role of internal atmosphere on fruit ripening and storability—a review

2011

Concentrations of different gases and volatiles present or produced inside a fruit are determined by the permeability of the fruit tissue to these compounds. Primarily, surface morphology and anatomical features of a given fruit determine the degree of permeance across the fruit. Species and varietal variability in surface characteristics and anatomical features therefore influence not only the diffusibility of gases and volatiles across the fruits but also the activity and response of various metabolic and physiological reactions/processes regulated by these compounds. Besides the well-known role of ethylene, gases and volatiles; O 2 , CO 2 , ethanol, acetaldehyde, water vapours, methyl salicylate, methyl jasmonate and nitric oxide (NO) have the potential to regulate the process of ripening individually and also in various interactive ways. Differences in the prevailing internal atmosphere of the fruits may therefore be considered as one of the causes behind the existing varietal variability of fruits in terms of rate of ripening, qualitative changes, firmness, shelf-life, ideal storage requirement, extent of tolerance towards reduced O 2 and/or elevated CO 2 , transpirational loss and susceptibility to various physiological disorders. In this way, internal atmosphere of a fruit (in terms of different gases and volatiles) plays a critical regulatory role in the process of fruit ripening. So, better and holistic understanding of this internal atmosphere along with its exact regulatory role on various aspects of fruit ripening will facilitate the development of more meaningful, refined and effective approaches in postharvest management of fruits. Its applicability, specially for the climacteric fruits, at various stages of the supply chain from growers to consumers would assist in reducing postharvest losses not only in quantity but also in quality.

“…In 1971, McManmon and Crawford (13) suggested that the diversification of the end products of fermentive metabolism could explain flooding tolerance in some species. Jackson et al (9) questioned whether ethanol itself could be responsible for anoxic injuries, but we (17,18) later demonstrated that ethanol can be toxic to specific plant systems even at concentrations comparable to those commonly found in plant tissues subjected to oxygen deficit.…”

Polyclonal antibodies able to recognize protein-acetaldehyde conjugates were produced and characterized. The antibodies react with sodium cyanoborohydride-reduced Schiff's bases between acetaldehyde and a protein, independently of the nature of the macromolecule binding the acetaldehyde moiety. Only conjugates between acetaldehyde or propionaldehyde and a protein are recognized; conjugates obtained with other aldehydes are not reactive. Results conceming the formation of acetaldehyde adducts with carrot (Daucus carota L.) proteins are presented as well as the presence of such conjugates in ethanoltreated carrot cell cultures, a system highly sensitive to the presence of ethanol in the culture medium.
