Hypersensitivity to Platanus acerifolia pollen: detection of the allergenic fractions
Background: Although the small clinical relevance of trees in pollinosis, as compared to other plants, is well known, in Barcelona the role of the plane tree (Platanus acerifolia), the most numerous tree species in the city, is significant. We have carried our a clinical and immunological study of the hypersensitivity to the pollen of Platanus acerifolia (hybrida) in Barcelona in order to asses...
متن کاملEffects of curtain-like pruning on distribution and seasonal patterns of carbohydrate reserves in plane (Platanus acerifolia Wild) trees.
The maintenance of plane trees (Platanus acerfolia Wild) by regular curtain-like pruning during the vegetative period induced modifications in the distribution and seasonal patterns of carbohydrate reserves in the perennial parts. The unpruned trees were characterized by high and fairly constant concentrations of starch in roots > 5 cm in diameter and a decreasing gradient of starch from the ba...
متن کاملIsolation and Functional Analyses of a Putative Floral Homeotic C-Function Gene in a Basal Eudicot London Plane Tree (Platanus acerifolia)
The identification of mutants in model plant species has led to the isolation of the floral homeotic function genes that play crucial roles in flower organ specification. However, floral homeotic C-function genes are rarely studied in basal eudicots. Here, we report the isolation and characterization of the AGAMOUS (AG) orthologous gene (PaAG) from a basal eudicot London plane tree (Platanus ac...
متن کاملbiocriteria demonstrating of air pollution stress on the plane-tree (platanus orientalis l.)
increasing energy demands associated with economic growth and industrialization have resulted in dramatic increases in air pollution emissions. air pollution damages the plant mainly by disrupting cell homeostatic conditions.in the present study, diverse plant criteria indicating air pollution from different levels including cell biochemistry, leaf and tree crown in the plane-tree were determin...
متن کاملIdentification and Functional Analysis of MicroRNAs and Their Targets in Platanus acerifolia under Lead (Pb) Stress
MicroRNAs (miRNAs) play important regulatory roles in development and stress responses in plants. Lead (Pb) is a non-essential element that is highly toxic to living organisms. Platanus acerifolia is grown as a street tree in cities throughout temperate regions for its importance in improving the urban ecological environment. MiRNAs that respond to abiotic stresses have been identified in plant...
