proteins in the roots of the perennial weeds chicory (cichorium intybus l.) and dandelion (taraxacum officinale weber) are associated with overwintering.	roots are the overwintering structures of herbaceous perennial weeds growing in temperate climates. during the fall they accumulated reserves which are remobilized when growth resumes in the spring. an 18kda (kilodalton) protein increases in both chicory and dandelion roots during the fall months. the proteins in both species are antigenically similar, and are recognized also by an antibody to a storage-protein deposited in jerusalem artichoke (helianthus tuberosus) tubers. in chicory, the prote ...	1990	24197187
glycaemic effects of traditional european plant treatments for diabetes. studies in normal and streptozotocin diabetic mice.	twelve plants used for the traditional treatment of diabetes mellitus in northern europe were studied using normal and streptozotocin diabetic mice to evaluate effects on glucose homeostasis. the plants were administered in the diet (6.25% by weight) and/or as decoctions or infusions in place of drinking water, to coincide with the traditional method of preparation. treatment for 28 days with preparations of burdock (arctium lappa), cashew (anacardium occidentale), dandelion (taraxacum officinal ...	1989	2743711
weed hosts of meloidogyne arenaria and m. incognita common in tobacco fields in south carolina.	thirty-two weed species common in south carolina and one cultivar of tobacco were evaluated as hosts of meloidogyne arenaria race 2 and m. incognita race 3 in the greenhouse. egg mass production and galling differed (p < 0.05) among weed species. chenopodium album, euphorbia maculata, and vicia villosa were good hosts of m. arenaria. amaranthus palmeri, rumex crispus, amaranthus hybridus, ambrosia artemisiifolia, lpomoea hederacea var. integriuscula, setaria lutescens, sida spinosa, portulaca ol ...	1988	19290313
transmission of tomato ringspot virus by xiphinema americanum and x. rivesi from new york apple orchards.	populations of xiphinema americanum and x. rivesi were collected from apple orchards in eastern and western new york and tested in the laboratory for ability to transmit tomato ringspot virus (tmrsv) to cucumber and dandelion. populations varied in the frequency with which they transmitted tmrsv, but this variation did not correspond to variation in disease prevalence in the orchard. the lower prevalence of tmrsv-incited disease in apple trees in western new york cannot be attributed to inabilit ...	1988	19290213
compositae dermatitis in childhood.	compositae dermatitis occurred in a 9-year-old boy with a strong personal and family history of atopy. positive patch test reactions were 2+ for dandelion (taraxacum officinale), false ragweed (ambrosia acanthicarpa), giant ragweed (ambrosia trifida), short ragweed (ambrosia artemisifolia), sagebrush (artemisia tridentata), wild feverfew (parthenium hysterophorus), yarrow (achillea millifolium), and tansy (tanacetum vulgare) and 1+ for dahlia species and english ivy (hedera helix). patch tests w ...	1987	3827282
flock size and habitat-dependent food and energy intake of foraging goldfinches.	during the breeding season goldfinches (carduelis carduelis l.) feed on milky ripe seeds of about 20 food plants. individual goldfinches joining a flock reduce the time spent vigilant with increasing flock size. therefore birds feeding in flocks get an increased intake of kernels per time unit. this was measured for five different food plants (dactylis glomerata (gramineae), knautia arvensis (dipsacaceae), senecio vulgaris, taraxacum officinale, tragopogon pratensis (compositae)). in large-sized ...	1986	28312098
