background & aim: the present study was to identify the medicinal plant species and introduced as one of the key priority areas for conservation and determination of endangered species were done. experimental: the method of plant collection in this region was classical method of regional plant taxonomic studies. collected plants were recognized and determined families, genera and species o...

Quillaia extracts (synonyms: quillaja extracts, bois de Panama, Panama bark extracts, quillai extracts, Quillay bark extracts, soapbark extracts; C.A.S. no. 68990-67-0, INS no. 999) are obtained by aqueous extraction of the milled inner bark or whole wood of Quillaja saponaria Molina (family Rosaceae), which is a large evergreen with shiny, leathery leaves and a thick bark, native to China and ...

Erwinia amylovora (E. amylovora) is the first bacterial plant pathogen described and demonstrated to cause fire blight, a devastating plant disease affecting a wide range of species including a wide variety of Rosaceae. In this study, we reported the lipopolysaccharide (LPS) core structure from E. amylovora strain CFBP1430, the first one for an E. amylovora highly pathogenic strain. The chemica...

The genus Rosa L. (Rosaceae) was recently treated floristically for North America, but range extensions and an additional taxon have been confirmed since then and are detailed here. These new reports document range extensions in the US and Canada of some native and introduced Rosa species, and new distributions and population data for several established Rosa hybrids (nothospecies). Some introd...

The diversity of early spring vascular fl ora was studied in the Sub-Pannonic steppic grassland in the village of Bilje, north eastern Croatia. In all, 109 plant taxa within 35 families were found. The highest number of taxa belongs to the families Poaceae, Fabaceae, Asteraceae, Caryophyllaceae, Lamiaceae and Rosaceae. Specifi c habitat conditions, characterized by moderately wet and moderately...

Lignin is one of the main components plant cell walls, which provides mechanical support for plants and also contributes to resisting against pathogenic fungi. In fruit industry, lignin content can affect quality fruit. The biosynthesis involves a variety enzymes, caffeoyl-CoA 3-O-methyltransferase ( CCoAOMT ) class methyltransferases that plays an essential role in biosynthesis. Studies have b...

Development of a green belt with suitable plant species around the source of emission can mitigate the atmospheric contamination. Selection of such plant species are required to combat air pollution based on their tolerance level. Present study was undertaken to evaluate the tolerance level of higher plants in East of Esfahan city, Iran, during 2011 in terms of assessing Air Pollution Tolerance...

Park green space is an important part of garden space, concentrated expression the diversity urban plants. In order to explore plants in park, a typical site Zhongshan Wuhan was selected for this survey. The species importance, richness index, index and evenness were used analyze characteristics plant diversity.There are total 184 114 genera 64 families Park. Among them, there 86 40 genera, 60 ...

orchard workers in north china are highly exposed to orchard pollens, especially peach and other rosaceae family pollens during pollination season. the aim of this study was to investigate whether occupational allergy to peach tree pollen as a member of rosaceae family is ige-mediated and to evaluate the cross-reactivity among rosaceae family pollens. allergen skin test and conjunctival challen...
