Abstract
Microsatellites undergo rapid changes over short evolutionary time periods which can be phylogenetically informative in related species. Here we show the repeat unit expansion of a (GA)(n)-type microsatellite in the process o f cultivation of rice from its wild ancestors. We amplified a microsatellit e locus harboring (GA)(n) repeats from several wild and cultivated rices. S equencing revealed art increase in repeat number from 14 in distantly relat ed wild rice species to 24 in the widely grown present-day indica rice cult ivars.
