the present study aimed to investigate representation of discourse markers and metadiscourse markers in conversations and readings of general elt coursebook series used in the language centers of iran. to this aim, four elt coursebooks popularly taught in language centers of this country were analyzed based on fung and carter’s (2007) framework regarding discourse markers and hyland’s (2005) fr...
Susceptibility Levels of Rhododendron Species and Hybrids to Phytophthora ramorum
The most important hosts of Phytophthora ramorum in Europe are cultivated Rhododendron species and hybrids. Since November 2002, EU emergency phytosanitary measures are being taken to prevent the introduction and spread of P. ramorum in Europe. Surveys at all commercial Rhododendron-growing premises are part of these measures and have led to P. ramorum findings at 2 to 5% of the inspected sites...
متن کاملChromosome segregation from cell hybrids
We searched for evidence of aberrant movement or position of segregant set chromosomes in Cbanded and G-11 -banded early-phase hamstermouse and hamster-human cell hybrids that had been prepared with minimal disruption. No evidence was obtained for an increased frequency of multipolar mitosis, delayed or precocious metaphase congression or anaphase segregation, or for exclusion of chromosomes fr...
متن کاملAnalysis of the Meiotic Segregation in Intergeneric Hybrids of Tilapias
Tilapia species exhibit a large ecological diversity and an important propensity to interspecific hybridisation. This has been shown in the wild and used in aquaculture. However, despite its important evolutionary implications, few studies have focused on the analysis of hybrid genomes and their meiotic segregation. Intergeneric hybrids between Oreochromis niloticus and Sarotherodon melanothero...
متن کاملMeiotic segregation and male recombination in interspecific hybrids of Drosophila.
Male hybrids between three pairs of Drosophila species show no substantial distortion of Mendelian segregation and no appreciable male recombination. These results do not support the theories that meiotic drive alleles of large effect are often fixed within species and that transposable genetic elements cause speciation.
