Plant material was collected from Costa Rica and supplied by Biotics Limited, University of Sussex, Brighton, UK. A vou...
While recent advances have been gained on genome evolution in angiosperm lineages, virtually nothing is known about karyotype evolution in the other group of seed plants, the gymnosperms. Here we used high density gene-based linkage mapping to compare the karyotype structure of two families of conifers (the most abundant group of gymnosperms) separated around 290 million years ago: Pinaceae and...
(Cryptomeria, Cunninghamia, Glyptostrobus, Metasequoia, Sciadopitys, Sequoia, Sequoiadendron, Taiwania, Taxodium). M. glyptostroboides is similar to Cupressaceae in the opposite arrangement of the vegetative and floral organs, whereas the pollen and wood anatomy of M. glyptostroboides are most similar to members of Taxodiaceae. It was on the basis of these morphological peculiarities that Metas...
Immunology, Phd In Science, Private Practice, Mexico City, Mexico. Background: The pollen dispersal by wind is a natural event of great biological significance and an etiological factor in the genesis of allergic respiratory diseases. This is the first such study carried out in the city of Toluca, Mexico. Objective: To present the data of collected pollen from September 2004 to September 2005. ...
BACKGROUND The Cupressaceae are an important cause of pollinosis, particularly in Mediterranean countries. Cypress pollen allergenic extracts are difficult to produce since they have a low protein and a high carbohydrate content and consequently accurate standardization of these extracts is essential for diagnosis and immunotherapy. METHOD Natural Cup s 1 was purified by a combination of hydr...
