“…Ethylene production in plants is influenced by a variety of environmental signals including drought, salinity, high temperature, flooding, light, carbon dioxide and oxygen, and mechanical wounding (3,26). Since the rate of ethylene production increases rapidly in wounded plant tissue, it has been suggested that ethylene plays an important role in signal transduction during the wound repair and defense response (1 1 (24). In tomato, STS has been shown to interrupt the ripening process (23); NBD has been shown to affect the expression of ethylene-induced genes (15 Wound-induced Changes in mRNA Populations Wounded pericarp tissues were incubated in the presence and absence of inhibitors of ethylene action, and the total poly(A)+ RNAs were isolated after 12 h from wounded and control tissues.…”

The contribution of wound-ethylene to wound-induced gene expression was investigated in unripe tomato pericarp using inhibitors of ethylene action. Wounded unripe tomato pericarp was treated with 2,5-norbornadiene or silver thiosulfate to inhibit specifically the induction of ethylene-dependent mRNA species. Poly(A)+ RNAs isolated from these tissues after 12 hours of wounding were translated in vitro in a rabbit reticulocyte lysate system and [35S]methionine-labeled polypeptides were compared to unwounded controls after separation by one and two-dimensional polyacrylamide gel electrophoresis. Results show that mechanical wounding induces a dramatic shift in gene expression (over 50 mRNA species) but expression of less than 15% of these genes is affected by the treatment with ethylene action inhibitors. A selective decrease in mRNAs coding for a 37 kilodalton doublet and 75 kilodalton polypeptides is observed in 2,5-norbomadiene and silver thiosulfate treated wounded pericarp. Levels of hydroxyproline-nch glycoprotein mRNAs induced in wounded tissue were not influenced by inhibitors of ethylene action.

The inhibitory effects of indole-3-acetic acid (IAA) and 1-aminocyclopropane-1-carboxylic acid (ACC) on elongation growth of pea (Pisum sativum L.) seedling roots were investigated in relation to the effects of these compounds on ethylene production by the root tips. When added to the growth solution both compounds caused a progressively increasing inhibition of growth within the concentration range of 0.01 to 1 micromolar. However, only ACC increased ethylene production in root tips excised from the treated seedlings after 24 hours. High auxin concentrations caused a transitory increase of ethylene production during a few hours in the beginning of the treatment period, but even in 1 micromolar IAA this increase was too low to have any appreciable effect on growth. ACC, but not IAA, caused growth curvatures, typical of ethylene treatment, in the root tips. IAA caused conspicuous swelling of the root tips while ACC did not. Cobalt and silver ions reversed the growth inhibitory effects induced by ACC but did not counteract the inhibition of elongation or swelling caused by IAA. The growth effects caused by the ACC treatments were obviously due to ethylene production. We found no evidence to indicate that the growth inhibition or swelling caused by IAA is mediated by ethylene. It is concluded that the inhibitory action of IAA on root growth is caused by this auxin per se.

“…2, Tab. 2). Since NBD inhibits ethylene action competitively (Sisler et al 1985, Veen 1985 this concentration-dependent inhibition of alternative pathway capacity suggests a regulatory role for endogenous ethylene in this induction. These results are in accordance with previous experiments (Gude and van der Plas 1985), where we observed an inhibition of alternative pathway capacity after suppressing ethylene formation in callus by AVG, a specific inhibitor of ethylene formation.…”

“…NBD is a volatile compound with a molecular structure that has two sites for binding to the ethylene hormone receptor in a competitive manner (Sisler and Yang 1984). NBD has been shown to counteract several wellknown ethylene effects, such as abscission of leaves (Sisler et al 1985), senescence of carnation flowers (Sisler et al 1983) or growth of carnation flower pistils (Veen 1985).…”

The growth (fresh and dry weight increase) of potato tuber (Solanum tuberosum L. cv. Bintje) callus discs was stimulated by incubation in air with 500 ppm 2,5‐norbornadiene (NBD, a competitive inhibitor of ethylene action) and inhibited by incubation in air with 4 000 ppm NBD. Ethylene formation by the callus was stimulated by NBD. The development of the alternative pathway, measured in isolated mitochondria was inhibited by NBD in a concentration‐dependent way. The alternative pathway capacity, measured in vivo, was inhibited by 4 000 ppm NBD, but not by 500 ppm. Uninhibited in vivo respiration, which consists of cytochrome path activity and alternative path activity, was stimulated by the treatment with 500 ppm NBD. The main contribution to this stimulation was made by the cytochrome pathway. In 4 000 ppm NBD‐treated callus, uninhibited respiration seemed to be unaffected as a consequence of an inhibited cytochrome path activity, which was compensated by a stimulated alternative path activity. Both in 500 and 4 OIK) ppm NBD‐treated callus the alternative path activity in vivo was stimulated. The regulatory role for endogenous ethylene in potato tuber callus is discussed in relation to: 1) The induction of respiratory pathways, 2) the supply of reduction equivalents in vivo and 3) growth.
