The effect of chilling on diurnal changes in activity of adenosine 5′-phosphosulfate sulfotransferase, glutathione reductase (EC 1.6.4.2) and glutathione transferase (EC 2.5.1.18) was analysed in the second leaf of Z 7, a chilling-tolerant, and Penjalinan, a chilling-sensitive maize (Zea mays L.) genotype. Nitrate reductase (EC 1.6.6.1) was measure...

Fungal components can cause allergic symptoms either through inhalation, ingestion or contact. Whereas respiratory allergy is thought to be induced by spores, allergic reactions following ingestion are attributed to other parts of the mushroom. Reports of food-related allergic reactions due to the edible mushroom Boletus edulis have occasionally be...

- Spores of the basidiomycete Pleurotus pulmonarius a species of the oyster mushrooms are widespread components in the air and established as causes of respiratory allergies. Recent reports indicate that aeroallergens such as mite allergens, pollen or animal dander may play an important role triggering atopic eczema in a subgroup of subjects with a...

The effect of chilling on the intercellular distribution of mRNAs for enzymes of assimilatory sulfate reduction, the activity of adenosine 5′-phosphosulfate reductase (APR), and the level of glutathione was analysed in leaves and roots of maize (Zea mays L). At 25 °C the mRNAs for APR, ATP sulfurylase, and sulfite reductase accumulated in bundle-sh...

Die Klasse der Ständerpilze (Basidiomyzeten) umfasst etwa 14000 verschiedene Arten der morphologisch größten Pilze. Ständerpilzsporen kommen in verschiedenen Regionen in bedeutenden Konzentrationen in der Luft vor und können die Ursache allergischer, IgE-vermittelter Atemwegserkrankungen wie Asthma oder Rhinitis sein. Ferner können die Ständerpilze...

Basidiospores are universal components in the air and established as important causes of respiratory allergies. Recent reports indicate that aeroallergens may aggravate eczematous skin lesions in subjects with atopic dermatitis (AD). The aim of the study was to investigate whether spores of Coprinus comatus, a species of basidiomycetes, may elicit...

Basidiomycetes spores are ubiquitously distributed, found throughout the year in outdoor and indoor air, and represent relevant sources of aeroallergens associated with allergy and asthma. Cloning and characterization of Coprinus comatus (shaggy cap mushroom) allergens is essential to elucidate their molecular characteristics and to improve the dia...

Although basidiospores are a major component of the air spora in many parts of the world, their clinical significance as triggers of respiratory allergy has rarely been demonstrated. Therefore, the class of basidiomycetes as an aeroallergen is not well known. To demonstrate a cause and effect relationship between respiratory allergy and basidiospor...

Basidiomycetes (fleshly mushrooms), the physically largest and most complex fungi are ubiquitous and produce large quantities of tiny spores (3–15 μm) contributing up to 30% of the total spore load [1]. Although fungal spores are generally accepted as causes of respiratory allergies, spores of this fungal class are not yet established as a s...

Fungal spores are universal components in the air and established as important causes of respiratory allergies. Whereas fungi imperfecti are accepted sources of allergic asthma and rhinitis, the significance of basidiomycetes as respiratory allergens is not established. The aims of the present study were to investigate the rate of sensitization in...

T cell recognition of drugs is explained by the hapten-carrier model, implying covalent binding of chemically reactive drugs to carrier proteins. However, most drugs are nonreactive and their recognition by T cells is unclear. We generated T cell clones from allergic individuals specific to sulfamethoxazole, lidocaine (nonreactive drugs), and cef-t...

T cells can recognize small molecular compounds like drugs. While haptens such as penicillinG bind covaleady to the MHC-peptide complex, the presentation of per se non reactive drugs like sulfamethoxazole (SMX) or lidocaine to drug specific T cell clones is unknown. To investigate a possible requirement for processing and drug metabolism the stimul...

The case of an alimentary allergy to olive fruit (Olea europea) and olive oil is reported. Although sensitization may have occurred through inhalation by another allergen such as pollen, the association between sensitization to olive or ash pollen, which are both cross-reactive, and the olive fruit allergy seems very unlikely. Since respiratory all...

We characterized the genes coding for the two dedicated enzymes of ethanolic fermentation, alcohol dehydrogenase (ADH) and pyruvate decarboxylase (PDC), and show that they are functional in pollen. Two PDC-encoding genes were isolated, which displayed reciprocal regulation: PDC1 was anaerobically induced in leaves, whereas PDC2 mRNA was absent in l...

Eukaryotic translation initiation factor eIF-4A is an ATP-dependent RNA helicase that is required for the binding of mRNA to ribosomes. Plant eIF-4A-like proteins are highly homologous to eIF-4As from yeast, mouse and Drosophila melanogaster. The pattern of intron-exon boundaries in eIF-4A-like genes are conserved within tobacco, but are not conser...

A pollen-specific sequence, NeIF-4A8, has been isolated from a cDNA library from mature pollen of Nicotiana tabacum cv. Samsun. NeIF-4A8 is a full-length cDNA whose deduced amino acid sequence exhibits high homology to the eucaryotic translation initiation factor eIF-4A from mouse, Drosophila and tobacco. eIF-4A is an RNA helicase which belongs to...
