Twenty-four start codon targeted (SCoT) markers were used to assess genetic diversity and population structure of indigenous, introduced and domesticated ramie (Boehmeria nivea L. Gaudich.). A total of 155 genotypes from five populations were investigated for SCoT polymorphism, which produced 136 amplicons with 87.5% polymorphism. Polymorphism information content and resolving power of the SCoT...

There is a rich population genetics literature on tests for whether an observed pattern of polymorphism, or an observed between-species difference, or both, can be accounted for with a standard drift model. Rejection of this hypothesis offers the possibility that selection may play a role, but (as we will see) other forces (such as population history) can also cause strong deviations from the n...

Tumours of the digestive system include a number malignant tumours such as oesophageal, gastric and colorectal cancers, which have highest incidence mortality rates in world. Their occurrence is related to variety factors, diet, environment genetics. As key enzyme process folate metabolism, MTHFR gene polymorphism plays an important role pathogenesis development gastrointestinal tumours. This p...

This article refers to viewing the role of molecular markers during analyzing genome plants and their importance in plant biotechnology. In recent years, we observed techniques programs for improving breeding preserving genetic resources has been observed, biochemical indicators which represent basic material through determining diversity between genotypes it is never affected by external surro...
