BACKGROUND Airborne Plantago pollen triggers respiratory allergies in Mediterranean countries. OBJECTIVES We aimed to study sensitization in patients with seasonal respiratory allergy and identify proteins of Plantago lanceolata pollen that could be responsible for hypersensitivity reactions in sensitized patients. We also determined the airborne pollen concentration of Plantago species from ...

BACKGROUND AND AIMS Parasitism is well understood to have wide-ranging deleterious effects on host performance in species thus far characterized. Photosynthetic performance reductions have been noted in the Striga-Zea mays association; however, no such information exists for facultative hemiparasitic plants and their hosts, nor are the effects of host species understood. METHODS Chlorophyll f...

BACKGROUND AND AIMS Rhinanthus minor is a root hemiparasitic plant that attacks a wide range of host species which are severely damaged by the parasite. Rhinanthus minor also attempts unsuccessfully to form connections to a range of non-hosts which in contrast are not damaged by the parasite; however, the underlying physiological basis of these differences is not fully understood. METHODS Bio...

To determine the evolutionary importance of parental environmental effects in natural populations, we must begin to measure the magnitude of these effects in the field. For this reason, we conducted a combined growth chamber-field experiment to measure parental temperature effects in Plantago lanceolata. We grew in the field offspring of controlled crosses of chamber-grown parents subjected to ...

The aim of my research was to screen secondary metabolites and antimicrobial activities of methanolic extracts of the leaves Vernonia amygdalina and Plantago lanceolata, and acetone extracts of the leaves Rosmarinus officinalis and Thymus schimperi against two bacteria (Staphylococcus aureus and Escherichia coli) and two fungi (Aspergillus niger and Fusarium oxysporum) using paper disc diffusio...

The theory of evolution via natural selection predicts that the genetic composition of wild populations changes over time in response to the environment. Different genotypes should exhibit different demographic patterns, but genetic variation in demography is often impossible to separate from environmental variation. Here, we asked if genetic variation is important in determining demographic pa...

leaf and root explants from 10 to 20 day– old seedlings of plantago lanceolata, were cultured on ms, msh, nt and b5 basal media with various concentrations of different plant growth regulators. the best callus induction was obtained with 0.4 mgl-1 2,4-d in msh i with 400 callus index. callus growth was significantly stimulated (p=0.05)with 0.8 mgl-1 2,4-d and 0.1 mgl-1 kin in msh ii, with 7...

Background: Several therapeutic effects including anti-asthma and dyspnea have been described for Plantago lanceolata. In the present study the antitussive effect of this plant was evaluated. Methods: The antitussive effects of aerosols of two different concentrations of Soxhlet and macerated ethanolic extracts, codeine and saline were tested by counting the number of coughs produced due to aer...
