Title
study the stability of genomic DNA in Cuminum cyminum in response to silver nitrate stress by using ISSR markers
Authors
Abstract
The toxicity of heavy metals in plants causes oxidative stress related to fat oxidation and membrane proteins and also causes DNA damage and toxicity. In our study, 4populations of Cuminum cyminum from Kerman, South Khorasan, Yazd and Isfahan were placed under stress of 8 different concentrations of silver nitrate. Then for evaluating the changes, 9 ISSR markers were used. Finally, the genetic differences were evaluated according to the control within any population by using two formula BSI and GTS that respectively, are based on common bands were observed between control and each concentration and Polymorphic bands of each sample.Results from BSI index in the four populations showed that by increasing the concentration of silver nitrate value this index is close to zero , which indicates that genetic differences between sample and control.Also check the index-based primers, primer 1 and 9 showed more genetic differences than others.With increasing concentrations, GTS index, which represents the amount or the rate of change of ISSR patterns of polymorphism is reduced.
