Sesquiterpene lactone mix detects contact allergy to these compounds present in the plant family Asteraceae. This marker is present in many baseline series. An additional marker is Compositae mix, which is not present in many baseline series. To investigate whether this allergen should be inserted into the Swedish baseline series, six dermatology centres representing the Swedish Contact Dermati...

PREMISE OF THE STUDY Like many other flowering plants, members of the Compositae (Asteraceae) have a polyploid ancestry. Previous analyses found evidence for an ancient duplication or possibly triplication in the early evolutionary history of the family. We sought to better place this paleopolyploidy in the phylogeny and assess its nature. METHODS We sequenced new transcriptomes for Barnadesi...

UNLABELLED PREMISE OF THE STUDY The Compositae (Asteraceae) are a large and diverse family of plants, and the most comprehensive phylogeny to date is a meta-tree based on 10 chloroplast loci that has several major unresolved nodes. We describe the development of an approach that enables the rapid sequencing of large numbers of orthologous nuclear loci to facilitate efficient phylogenomic ana...

Of the approximately 250,000 species of flowering plants, nearly one in ten are members of the Compositae (Asteraceae), a diverse family found in almost every habitat on all continents except Antarctica. With an origin in the mid Eocene, the Compositae is also a relatively young family with remarkable diversifications during the last 40 My. Previous cytologic and systematic investigations sugge...

Among the sources of homoeopathic medicines vegetable kingdom is major source. Compositae family one largest plant giving more than 60 to homoeopathy. Plants compositae are important in herbal and folk medicine since antiquity. In system medicine, from Asteraceae were used for shock, spasms, convulsions, traumas, bruises, liver blood disorders, respiratory problems, fever, sepsis worm infestati...

The green organs, especially the leaves, of many Compositae plants possess characteristic aromas. To exploit the utility value of these germplasm resources, the constituents, mainly volatile compounds, in the leaves of 14 scented plant materials were qualitatively and quantitatively compared via gas chromatography-mass spectrometry (GC-MS). A total of 213 constituents were detected and tentativ...

Summary The recently described Werneria praetermissa (Compositae: Senecioneae: Senecioninae) from northwestern Argentina (Jujuy, Salta) and southern Bolivia (Tarija) is transferred to Rockhausenia .
