Abstract:
The sucrose exchange characteristics at the level of contact between a host, Pelargonium zonale (L.) Aiton, and a parasite, Cuscuta reflexa Roxb., were investigated by studying the effects of fusicoccin (FC). With isolated haustoria of Cuscuta, FC stimulated the activity of the plasma membrane ATPase. This action was established by FC-increased proton extrusion. FC-increased O2 consumption and FC-increased 86Rb uptake. Nevertheless, FC strongly inhibited (by 30-50%) sucrose uptake and strongly enhanced (by 42-47%) sucrose release. These results, which are discussed in relation to the physiolog

Abstract:
To obtain the structural diversity of bioactive compounds similar to cotylenins and fusicoccins that modulate 14-3-3 protein-protein interactions in eukaryotes, screening tests were carried out using the lettuce seed dormancy breaking-assay. An acetone extract of the liverwort Plagiochila sciophila exhibited significant activity against the seeds in the presence of the plant hormone abscisic acid. Activity-guided fractionation of the extract afforded the isolation of seven novel fusicoccane-type diterpenoids, named fusicosciophins A-E (1–5), 8-deacetyl (6) and 9-deacetyl fusicosciophin E (7).

Abstract:
Fusicoccin (FC), a natural diterpene glucoside able to stimulate electrogenic H+ extrusion in higher plants, has been shown to stimulate the phosphorylation of a polypeptide of molecular mass approx. 33 kDa in intact cultured cells of sycamore (Acer pseudoplatanus). The effect is specific, rapid and insensitive to cycloheximide. The presence of the 33 kDa polypeptide and the stimulation by FC have been observed in SDS-containing cell homogenates and in the microsomal and soluble fractions after cell fractionation.

Abstract The rate and total emergence of lettuce (Lactuca sativa L. ‘Empire’) seedlings incubated at 33°C for 10 hr, alternating with 23° for 14 hr, was markedly increased by seed treatment with 0.5 mM fusicoccin (FC). Neither gibberellic acid (GA) nor kinetin (K) were effective in improving emergence when used alone. The combination of FC with GA or K appeared to give a synergistic enhancement of emergence rate. The radicle elongation of seedlings was reduced by seed treatment with FC, K, or combinations of FC, GA, and K in tests at 20°. The greatest reductions were caused by combinations tha

Abstract:
Fusicoccin is the α glucoside of a carbotricyclic diterpene, produced by the fungus Phomopsis amygdali (previously classified as Fusicoccum amygdali), the causal agent of almond and peach canker disease. A great interest in this molecule started when it was discovered that it brought about an irreversible stomata opening of higher plants, thereby inducing the wilting of their leaves. Since then, several studies were carried out to elucidate its biological activity, biosynthesis, structure, structure-activity relationships and mode of action. After sixty years of research and more than 1800 pub

Abstract:
Fusicoccin (FC) is a well-known phytotoxin able to induce in Acer pseudoplatanus L. (sycamore) cultured cells, a set of responses similar to those induced by stress conditions. In this work, the possible involvement of peroxynitrite (ONOO−) in FC-induced stress responses was studied measuring both in the presence and in the absence of 2,6,8-trihydroxypurine (urate), a specific ONOO− scavenger: (1) cell death; (2) specific DNA fragmentation; (3) lipid peroxidation; (4) production of RNS and ROS; (5) activity of caspase-3-like proteases; and (6) release of cytochrome c from mitochondria, variati

By using pharmacological approaches and laser scanning confocal microscopy based on 4,5-diaminofluorescein diacetate (DAF-2DA), the relationship between the inhibition of dark-induced stomatal closure caused by fusicoccin (FC) and the changes of nitric oxide (NO) levels in guard cells in broad bean was studied. The results show that, like 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (c-PTIO), a NO scavenger and NG-nitro-L-Arg-methyl ester (L-NAME), an inhibitor of nitric oxide synthase (NOS), FC inhibited stomatal closure induced by darkness, and reduced the levels of NO i

AbstractAbstract In isolated embryos from dormant barley grains, synergistic effects of fusicoccin (FC) and gibberellic acid (GA3) were observed on the induction of α-amylase mRNA expression. However, no α-amylase mRNA expression could be induced by both agents in embryos from non-dormant grains. Both light- and electron-microscopy studies demonstrated that there were large numbers of starch granules present in mature embryos (mainly in scutellum) from dormant barley grains but none or almost none in embryos from non-dormant grains.

The plant vacuole is a very dynamic organelle that can occupy more than 90% of the cell volume and is essential to plant cell growth and development, the processes in which auxin (indole-3-acetic acid, IAA) is a central player. It was found that when IAA or FC (fusicoccin) was present in the control medium of vacuoles isolated from red beet taproots at a final concentration of 1 µM, it increased their volume to a level that was 26% or 36% higher than that observed in the control medium without growth regulators, respectively.

Abstract:
Sweet corn roots colonized with the T-22 strain of the common rhizosphere fungus grow substantially faster than roots of plants not so colonized. We tested whether this growth enhancement was a consequence of the fungus affecting auxin regulation of cell elongation. In corn roots, auxin acts an inhibitor of growth, maintaining the rate below its short-term maximum potential. The first hypothesis was that the fungus secretes an auxin inhibitor, and thereby reduces the auxin limitation of growth. Apical segments (5 cm) were incubated in media conducive to elongation, supplemented with 0.1 μm ind

L’identificazione della fusicoccina come metabolita responsabile degli effetti tossici di Phomopsis amygdali, dovuti alla sua capacità di attivare irreversibilmente l’H+-ATPasi di plasmalemma, ha dato impulso al chiarimento del meccanismo molecolare di azione della tossina. L’H+-ATPasi di plasmalemma è, ad oggi, l’unico bersaglio dell’azione della FC individuato. La mancata identificazione di siti di legame per la FC in batteri, lieviti, funghi e animali ha fatto ritenere che l’azione della tossina fosse quindi ristretta al regno vegetale.
