Abstract
Microsatellites undergo rapid changes over shortevolutionary time periods which can be phylogeneticallyinformative in related species. Here we show the repeatunit expansion of a (GA)n-type microsatellite in the process of cultivation of rice from itswild ancestors. We amplified a microsatellite locusharboring (GA)n repeats from several wild andcultivated rices. Sequencing revealed an increase inrepeat number from 14 in distantly related wild ricespecies to 24 in the widely grown present-day indicarice cultivars.
