Brachypodium Genomics

Brachypodium distachyon (L.) Beauv. is a temperate wild grass species; its morphological and genomic characteristics make it a model system when compared to many other grass species. It has a small genome, short growth cycle, self-fertility, many diploid accessions, and simple growth requirements. In addition, it is phylogenetically close to economically important crops, like wheat and barley, and several potential biofuel grasses. It exhibits agricultural traits similar to those of these target crops. For cereal genomes, it is a better model than Arabidopsis thaliana and Oryza sativa (rice), the former used as a model for all flowering plants and the latter hitherto used as model for genomes of all temperate grass species including major cereals like barley and wheat. Increasing interest in this species has resulted in the development of a series of genomics resources, including nuclear sequences and BAC/EST libraries, together with the collection and characterization of other genetic resources. It is expected that the use of this model will allow rapid advances in generation of genomics information for the improvement of all temperate crops, particularly the cereals

Prevalence of allergic rhinitis and risk factors in school children

Objective: To evaluate the prevalence and the risk factors of allergic rhinitis in a particular area. Methods: The main study group consisted of all school children in Kemalpasa district aged 13-14 years. Children with current rhinitis based on responses given in ISAAC questionnaire survey were further evaluated for confirmation. Parents responded to a more detailed questionnaire about allergic diseases and risk factors. Then peak nasal inspiratory flow (PNIF) was evaluated to objectively assess nasal patency. Skin-prick test was performed for ten common allergens. Results: The questionnaire was answered by 90.8% (1373) of children. The prevalence of physician-diagnosed AR was 11.1%. Current rhinitis was found to be 31.3%. Of this group, 55.0% were admitted for the parent questionnaire and tests. Precisely, 90.3% of children accepted PNIF evaluation, and %10.1 of them had a nasal obstruction. Skin-prick tests revealed allergy for at least 1 allergen in 16.6% of children. The present study showed that the children with maternal allergic rhinitis history had 2,18 fold, and the children with seasonal allergic rhinitis had 2,11 fold higher possibility of sensitization to an allergen. The probability of perennial allergic rhinitis was 3,1 fold higher in the children who had siblings with allergic rhinitis. Conclusion: We included all children in a specific age group living in an area in our survey. As well as we found the prevalence of current rhinitis with the ISAAC questionnaire; we also evaluated peak nasal inspiratory flow and used skin-prick tests that yielded objective results

Diploid brachypodium distachyon of Turkey: molecular and morphological analysis

Brachypodium distachyon is a model species for the grass family, Poaceae, which includes major cereal crops such as wheat and barley. The aim of this study were to assess morphological and phylogenetic relationships among diploid accessions of Brachypodium representing diverse geographic regions of Turkey based on Sequence related Amplified Polymorphism (SRAP) analyses. The similarity matrix indicated close relation among species used in the section using SRAP primer combinations, produced 156 fragment bands, of which 120 were polymorphic. Genetic distance ranged from 0.03 to 0.62. Plant genotypes were grouped into two major clusters based on SRAP analysis. There was a high level of diversity among the native diploid Brachypodium genotypes. These genotypes can be used for a better understanding of grass genomics
