Microsatellite (or simple sequence repeat (SSR)) markers are based on repeated sequences of one- to six-base core sequences (typically two to four), found interspersed in the genome. Since the sequences flanking the repeats are conserved, but the length of the repeat itself varies, these markers … Ver mais Although microsatellite markers are a robust and useful tool in studying grapevine genetics, their development is time-consuming and expensive (prior to the draft grapevine genome sequence being released). The … Ver mais Microsatellite variation is thought to arise from mismatch errors leading to unequal crossover among the repeats.
