“…Reversible protein phosphorylation is a core component of eukaryoti¢ cell signalling [36], with plant-pathogen interaction being no exception [37]. Inhibition of protein phosphorylation by the kinase inhibitor K-252a has been shown to prevent AOS release in soybean [4,38], parsley [22] and harpin-elicited tobacco cell suspensions [32]. Here we have shown that it also prevents harpin.induced AOS generation in Arabidopsis cell cultures.…”

“…These AOS include superoxide (O[-), hydrogen peroxid,: (H202), and the hydroxyl radical (OH') [1,2]. The signifivance of AOS acting as a signal towards host defense in plant-pathogen interactions has been demonstrated by HaO2.mediated oxidative cross-linking of the plant cell wall during HR [3,4], phytoalexin formation in cultured cells [5][6][7] and induction of cellular protection genes [4].…”

“…This process is believed to be a one of the most rapid inducible defense responses in plants, being initiated within 2 min (Bradley et al, 1992;Levine et al, 1994). The factors participating in this primary defense response are unknown.…”

The cDNA encoding the 182 amino acid long precursor stellacyanin from Cucumis sariwus was isolated and characterized. The protein precursor consists of four sequence domains: I, a 23 amino acid hydrophobic N-terminal signal peptide with features characteristic of secretory proteins; 11, a 109 amino acid copper-binding domain; 111, a 26 amino acid hydroxyproline-and serine-rich peptide characteristic of motifs found in the extensin family, extracellular structural glycoproteins found in plant cell walls; and IV, a 22 amino acid hydrophobic extension. Maturation of the protein involves posttranslational processing of domains I and IV. The copper-binding domain (domain 11), which shares high sequence identity with other stellacyanins, has been expressed without its carbohydrate attachment sites, refolded from the Escherichia coli inclusion bodies, purified, and characterized by electronic absorption, EPR, ESEEM, and RR spectroscopy. Its spectroscopic properties are nearly identical to those of stellacyanin from the Japanese lacquer tree Rhus verniciferu, the most extensively studied and best characterized stellacyanin, indicating that this domain folds correctly, even in the absence of its carbohydrate moiety. The presence of a hydroxyproline-and serine-rich domain I11 suggests that stellacyanin may have a function other than that of a diffusible electron transfer protein, conceivably participating in redox reactions localized at the plant cell wall, which are known to occur in response to wounding or infection of the plant.

“…The induction of defensive metabolism is often associated with increased tissue levels of reactive oxygen species (ROS) and increased cellular levels of free cytosolic calcium [4]. The increase in ROS is probably an important part in the process of defense induction and can also constitute a defense function per se [4,5].…”

“…Many plant stressors, biotic as well as abiotic, are associated with oxidative stress and increased levels of reactive oxygen species such as hydrogen peroxide (H202), superoxide ions (02-) and hydroxyl radicals ('OH) [5,7]. Exposure of plant tissue to UV-B light [8,18,19] or 2,2'-azobis(2-amidinopropane)dihydrochloride (AAPH) [20] is associated with increased antioxidative defense metabolism.…”
