Rapid genomic alteration in an 'incompatible' pair of maize reciprocal F1 hybrids--a possible cause for the accumulation of inter-strain genetic diversity.

Abstract excerpt

Recent studies have revealed unexpected high levels of genetic variation across maize inbred lines, which led to violation of colinearity that holds even between species of the grass family. Although activity of certain mobile elements is likely a contributing factor for this kind of intra-specific variations in maize, it is conceivable that other mechanisms might be involved. Here, we report that de novo genetic...
