Detection of genetic variations in orobanche crenata using inter simple sequence repeat (ISSR) markers

Abstract

Abstract Background This recent investigation aimed to detect and characterize the genetic variabilities and genetic similarity in Orobanche crenata collected from naturally Orobanche-infested field at Gemmeiza Research Station, Agriculture Research Center (ARC), Egypt. Five different ISSR primers were used in this study. Results Obtained results showed that a huge genetic variation has been detected by these ISSR primers; moreover, there were clear relationship/genetic similarity between and within all collected O. crenata parasite plants. However, the results revealed that there were high relationships where similarity matrix ranged from 0.837 (the highest) between R4 and R17 followed by 0.831 for R4/R25 and in the end, the lowest one was R1/R29 similarity matrix 0.655. Conclusions It was noticed that the relationship and similarity did not reach 100% but the maximum was 83.7% (there were no identical plants); therefore, each Orobanche plant in this study was different genotype than neighboring plant within location.
