Extensive microsatellite variation in rice induced by introgression from wild rice (Zizania latifolia Griseb.).

ABSTRACT:

Background

It is widely accepted that interspecific hybridization may induce genomic instability in the resultant hybrids. However, few studies have been performed on the genomic analysis of homoploid hybrids and introgression lines. We have reported previously that by introgressive hybridization, a set of introgression lines between rice (Oryza sativa L.) and wild rice (Zizania latifolia Griseb.) was successfully generated, and which have led to the release of several cultivars.

Methodology

Using 96 microsatellite markers located in the nuclear and organelle genomes of rice, we investigated microsatellite stability in three typical introgression lines. Expression of a set of mismatch repair (MMR) genes and microsatellite-containing genes was also analyzed.
