等位基因重组先前已显示出增加各种真核生物物种的序列的GC含量。成簇串联重复基因之间的异位重组也被证明会增加它们的GC含量。在这里，我们表明，在酵母和拟南芥基因组的重复区域中发现的分散基因之间的基因转换也增加了它们的GC含量，当这些基因超过88%相似时。
Allelic recombination has previously been shown to increase the GC-content of the sequences of a wide variety of eukaryotic species. Ectopic recombination between clustered tandemly repeated genes has also been shown to increase their GC-content. Here we show that gene conversions between the dispersed genes found in the duplicated regions of the yeast and Arabidopsis genomes also increase their GC-content when these genes are more than 88% similar.
