Cross‐reactivity between Platanus pollen and vegetables
Allergy, 2002Co-Authors: J. C. Miralles, F. Guillen, Francisco Caravaca, Manuel Lombardero, J. M. NegroAbstract:Background: Several associations have been described between tree and plant pollens and certain foods. The objective of this study is to verify whether there is cross-reactivity between Platanus pollen and vegetable origin foods. Methods: We selected 56 patients allergic to vegetable foods and subjected them to cutaneous tests with aeroallergens and vegetable foods. A statistical analysis was performed to evaluate the association of Platanus pollen with foods and with other aeroallergens. Later, a specific IgE determination was performed as well as a RAST (radioallergosorbent) inhibition experiment, to verify the existence of cross-reactivity in vitro. Results: In the cutaneous tests we found a positive correlation between Platanus pollen and hazelnut, peanut, banana and celery. The results of the RAST inhibition experiment indicate an important cross-reactivity between the pollen of Platanus acerifolia and hazelnut and banana fruit, and an intermediate cross-reactivity with celery and peanut. Conclusion: We have described an association between the pollen of the Platanus tree and some vegetable foods such as hazelnut, banana, peanut and celery. This association could be explained by the in vitro IgE cross-reactivity detected.

Platanus pollen season in Andalusia (southern Spain): trends and modeling.
Journal of environmental monitoring : JEM, 2011Co-Authors: Purificación Alcázar, Herminia García-mozo, María Del Mar Trigo, Luis Ruiz, Francisco José González-minero, Pablo J. Hidalgo, Consuelo Díaz De La Guardia, Carmen GalánAbstract:Platanus is a major cause of pollen allergy in many Spanish cities. The present paper reports an analysis of Platanus pollen season throughout the Andalusia region (southern Spain), which has among the highest pollen counts and the highest incidence of Platanus-related allergies in Europe. The main aim was to analyze pollen season trends from 1992 to 2010 in Andalusia; models were also constructed to forecast the start of the season. Daily pollen counts were recorded using Hirst-type volumetric spore-traps. Pollen season start-dates were very similar at all sites, usually occurring in March. The pollen season was delayed over the study period. The Pollen-season duration and Pollen index generally increased throughout the study period. The starting date for temperature accumulation was around the 10th February, although the threshold temperatures varied by site. The regional model for Andalusia failed to provide sufficiently accurate results compared with sub-regional or local models. For modeling purposes, three sub-regions are recommended: Inland, East Coast and West Coast.

Airborne plane-tree (Platanus hispanica) pollen distribution in the city of Córdoba, South-western Spain, and possible implications on pollen allergy.
Journal of investigational allergology & clinical immunology, 2004Co-Authors: Purificación Alcázar, Paloma Cariñanos, De Castro C, Guerra F, Carmen Moreno, Eugenio Domínguez-vilches, Carmen GalánAbstract:Summary Plane-trees are widely grown in Spain as ornamentals. This taxon releases large amounts of pollen into the air and this pollen type seems to have proved implications on pollinosis. The aim of this study was to analyse airborne Platanus pollen content in the air of Cordoba (South-western Spain) over the last 10 years, and its distribution in different areas of the city, as well as to consider possible implications regarding pollen allergies. Results revealed that Platanus pollen concentrations have been at their highest over the last 5 years. Within the city, the lowest pollen concentrations were in Northern areas of the city. Nevertheless, concentrations high enough to be of risk are reached over the whole city. All the patients studied presented symptoms during the Platanus pollen season. We can therefore conclude that plane pollen presents a risk for the whole city although symptoms are more intense and persistent in districts with a higher number of plane-trees. Platanus allergy is a particular problem for citydwellers, where these trees are commonly used as ornamentals.

Transcriptome sequencing, molecular markers, and transcription factor discovery of Platanus acerifolia in the presence of Corythucha ciliata
Scientific data, 2019Co-Authors: Mengzhu Gao, Mengmeng Jiao, Asier Gonzalez-uriarte, Chen LuoAbstract:The London Planetree (Platanus acerifolia) are present throughout the world. The tree is considered a greening plant and is commonly planted in streets, parks, and courtyards. The Sycamore lace bug (Corythucha ciliata) is a serious pest of this tree. To determine the molecular mechanism behind the interaction between the London Planetree and the Sycamore lace bug, we generated a comprehensive RNA-seq dataset (630,835,762 clean reads) for P. acerifolia by sequencing both infected and non-infected leaves of C. ciliata using the Illumina Hiseq 4000 system. We assembled the transcriptomes using the Trinity De Novo assembly followed by annotation. In total, 121,136 unigenes were obtained, and 80,559 unigenes were successfully annotated. From the 121,136 unigenes, we identified 3,010,256 SNPs, 39,097 microsatellites locus, and 1,916 transcription factors. The transcriptomic dataset we present are the first reports of transcriptome information in Platanus species and will be incredibly useful in future studies with P. acerifolia and other Platanus species, especially in the areas of genomics, molecular biology, physiology, and population genetics.
