Disease relevance of Dactylis

• The objectives of this study were to determine the effect of a cellulase (from Trichoderma longibrachiatum) alone or combined with a bacterial inoculant (Lactobacillus plantarum and Pediococcus cerevisiae) or formic acid on composition, intake, and digestibility of orchardgrass (Dactylis glomerata L.) and alfalfa (Medicago sativa L.) silages [1].
• The amount of histamine released from blood leucocytes by allergen, the amount of allergen required to release 50% histamine and the total IgE and IgE specific for Dactylis glomerata are compared in nine hay fever patients and five control individuals [2].

High impact information on Dactylis

• Study of the epitope structure of purified Dac G I and Lol p I, the major allergens of Dactylis glomerata and Lolium perenne pollens, using monoclonal antibodies [3].
• Inhibition of the seasonal IgE increase to Dactylis glomerata by daily sodium chloride nasal-sinus irrigation during the grass pollen season [4].
• Monoclonal antibodies were produced against Dac g 4, a purified major basic allergen from Dactylis glomerata pollen [5].
• MATERIAL AND METHODS: Fifty-three patients with a well-documented clinical history of seasonal AR sensitized to Dactylis glomerata and Olea europaea pollens were included in a randomized clinical trial [6].
• Pollen starch granules (PSG) extracted from Dactylis glomerata and coated with trinitrophenol (TNP) were used as a model of an inhaled organic particulate allergen [7].

Biological context of Dactylis

• Nucleotide sequence of cDNA encoding the group II allergen of cocksfoot/orchard grass (Dactylis glomerata), Dac g II [8].
• Oxygen consumption by PDV as a percentage of whole-animal O2 consumption was not different (P greater than .10) for steers when fed orchardgrass (27.2) or when fed alfalfa (23.6) [9].
• Kinetics of cell-wall digestion of orchardgrass and alfalfa silages treated with cellulase and formic acid [10].
• Influence of low temperature preincubation on somatic embryogenesis and ethylene emanation from orchardgrass leaves [11].

Associations of Dactylis with chemical compounds

• We have purified a 24/25 kd allergen from orchard grass pollen (Dactylis glomerata) that has an allergenic potency similar to that of the major group I allergen [12].
• Cocksfoot mottle sobemovirus supports replication and encapsidation of the viroid-like satellite RNA (sat-RNA) of lucerne transient streak virus (LTSV) in two monocotyledonous species, Triticum aestivum and Dactylis glomerata [13].
• Comparison of the population in animals fed either orchardgrass hay or 60% corn-40% orchardgrass (60-40) indicated little or no difference for the percentage of bacteria utilizing glucose, pectin, xylan, or mannitol [14].
• Increases in the percentages of xylose-, cellobiose-, Glycerol-, and lactate-utilizing bacteria occurred with the orchardgrass hay ration, whereas the percentage of starch-digesting bacteria was increased significantly (P less than 0.01) in the animals fed the 60-40 ration [14].
• Group V allergens in grass pollens: IV. Similarities in amino acid compositions and NH2-terminal sequences of the group V allergens from Lolium perenne, Poa pratensis and Dactylis glomerata [15].

Gene context of Dactylis

• Sequencing of the PCR-amplified S thioredoxin region from wheat, barley, rye and Dactylis revealed that this is a highly conserved gene with 94-97% sequence similarity with the corresponding Phalaris S gene [16].
• Heterogeneity of grass pollen allergens (Dactylis glomerata) recognized by IgE antibodies in human patients sera by a new nitrocellulose immunoprint technique [17].
• Inhibition of the passive cutaneous anaphylaxis reaction to Dactylis glomerata pollen allergens by a purified component of this pollen [18].
• Cocksfoot/orchard grass (Dactylis glomerata) anther cDNA clones encoding the group II allergen Dac g II were previously isolated on the basis of immunoreactivity of human, rabbit, and murine antibodies with a 24-kDa protein expressed as a fusion protein with beta-galactosidase [8].
• Recombinant pollen allergens from Dactylis glomerata: preliminary evidence that human IgE cross-reactivity between Dac g II and Lol p I/II is increased following grass pollen immunotherapy [19].

Analytical, diagnostic and therapeutic context of Dactylis

• We used secondary ion mass spectrometry to image cellular targets of nitrogen oxides (widespread air pollutants) in pollen grains of birch (Betula verrucosa Ehrh.) and cockfoot (Dactylis glomerata L.). The pollen samples were exposed to air supplemented with high doses of 15NO [20].
• A mouse monoclonal antibody was produced against the most frequent allergen Ag Dg1ief, purified from the Dactylis glomerata grass pollen by isoelectric focusing [21].
• Experiments are reported for the evaluation of an indirect ELISA using peroxidase conjugate for the detection of IgG antibodies to Dactylis glomerata (DG), a grass pollen antigen frequently responsible for allergic rhinitis and asthma [22].
