dna methylation as epigenetic mark plays a key role in normal differential and developmental processes as well as in dynamic gene regulation at the genomic level. to assess dna methylation pattern in different developmental stages of aeluropus littoralis, methylation sensitive amplified polymorphism (msap) was used. methylation and demethylation status at the ccgg recognition site were tracked ...

in order to study the effect of planting date on phonological stages and quantity traits of four cultivars of winter rapeseed, an experiment was carried out in 2008-2009 at the research field of agriculture research station of boyerahmad. the experiment was carried out in using factorial with randomized complete block design and four replications. four planting dates (september 12, september 22...

introdouction: age estimation is an important issue in forensics, particularly for treatment planning and determining patients’ rights. radiographic evaluation of the third molar developmental stage is a significant criterion for age estimation. the pattern of tooth development is largely heritable and varies from race to race. the objective of this study was to radiographically examine and com...

Sea Urchin is one of the most useful tools in developmental biology studies because this organism has the simplest kind of developmental stages. We aimed to determine developmental stages and timetable of Echinometra mathaei embryo (the species of Persian Gulf). The spawning of E. mathaei was induced by 0.5M KCl injection (1ml) into the coelomic cavity. After fertilization, embryos were placed ...
