Microsatellite marker identification using genome screening and restriction-ligation
We have identified a fast and easy method for finding microsatellite markers that utilizes genome screening with inter-simple sequence repeat (ISSR) primers to detect microsatellite regions and to obtain sequence information flanking one side of the microsatellites and a restriction-ligation techniq...

| description | We have identified a fast and easy method for finding microsatellite markers that utilizes genome screening with inter-simple sequence repeat (ISSR) primers to detect microsatellite regions and to obtain sequence information flanking one side of the microsatellites and a restriction-ligation technique with a specific adaptor to allow sequence walking to obtain sequence information flanking the other side of the microsatellites. Two main alternatives of the method (with or without cloning) are presented. We successfully utilized the method when identifying microsatellite markers for 21 bryophyte species, three algal species, and for the raccoon dog. The proportion of polymorphic markers equaled 95%. We observed that microsatellites are commonly found within the sequenced ISSR amplification products (54% in the present study), in which case specific primers can be identified for the microsatellite without a further restriction-ligation step. It is evident that the DNA regions amplified by ISSR markers commonly represent microsatellite hotspots. We propose that the identified method and the knowledge of the common presence of additional microsatellite repeats within ISSR amplification products are especially attractive to researchers who conduct small-scale microsatellite identification, such as researchers in population genetics and conservation biology. |
