wall carbohydrates, and organic acids. The hydroxycinnamic acid amides with tyramine and octopamine are also common types of conjugates.2) The formation of the amides serves a defensive purpose in solanaceous plants such as potato,3・4) tobacco5) and tomato.6) Various forms of stress, including physical injury, infection with pathogens and elicitor-treatments, induce the accumulation of hydroxycinnamic acid amides. It has been suggested that these amide compounds are integrated into the cell wall and eventually form a phenolic barrier against pathogens and herbivores.'-9) Tyramine IV-hydroxycinnamoyltran-

Is DNA methylation modulated by wounding-induced oxidative burst in maize?
Plants respond to environmental changes by modifying gene expression. One of the mechanisms regulating gene expression is methylation of cytosine to 5-methylcytosine (m(5)C) which modulates gene expression by changing chromatin structure. Methylation/demethylation processes affect genes that are controlled upon environmental stresses. Here, on account of the regulatory role of m(5)C, we evaluat...
متن کاملCharacterization of a Maize Wip1 Promoter in Transgenic Plants
The Maize Wip1 gene encodes a wound-induced Bowman-Birk inhibitor (BBI) protein which is a type of serine protease inhibitor, and its expression is induced by wounding or infection, conferring resistance against pathogens and pests. In this study, the maize Wip1 promoter was isolated and its function was analyzed. Different truncated Wip1 promoters were fused upstream of the GUS reporter gene a...
متن کاملOP 4 . 1 The involvement of protein kinase A in humoral immune response of Galleria mellonella
The major challenges which plants have to withstand is osmotic stress (caused by drought, high and low temperature and high salinity), and wounding (caused by mechanical damage, f. ex. wind or herbivorous). Plant cells respond to these abiotic stresses by a multi-component defense strategy. Several families of protein kinases are involved in plant stress signaling. Among them are members of mit...
متن کاملA wound-responsive and phospholipid-regulated maize calcium-dependent protein kinase.
Using protein sequence data obtained from a calcium- and phospholipid-regulated protein kinase purified from maize (Zea mays), we isolated a cDNA encoding a calcium-dependent protein kinase (CDPK), which we designated ZmCPK11. The deduced amino acid sequence of ZmCPK11 includes the sequences of all the peptides obtained from the native protein. The ZmCPK11 sequence contains the kinase, autoregu...
متن کاملElectrical signaling along the phloem and its physiological responses in the maize leaf
To elucidate the role of electrical signaling in the phloem of maize the tips of attached leaves were stimulated by chilling and wounding. Two different signals were detected in the phloem at the middle of the leaf using the aphid stylet technique: (1) action potentials (AP) arose in the phloem after chilling; and (2) variation potentials (VPs) were evoked after wounding the leaf tip. Combined ...
متن کاملEuropean Corn Borer (Ostrinia nubilalis) Induced Responses Enhance Susceptibility in Maize
Herbivore-induced plant responses have been widely described following attack on leaves; however, less attention has been paid to analogous local processes that occur in stems. Early studies of maize (Zea mays) responses to stem boring by European corn borer (ECB, Ostrinianubilalis) larvae revealed the presence of inducible acidic diterpenoid phytoalexins, termed kauralexins, and increases in t...
