Comparative gene expression profiles between heterotic and non-heterotic hybrids of tetraploid Medicago sativa.

BMC plant biology - 13 Aug 2009

Abstract excerpt

BACKGROUND: Heterosis, the superior performance of hybrids relative to parents, has clear agricultural value, but its genetic control is unknown. Our objective was to test the hypotheses that hybrids expressing heterosis for biomass yield would show more gene expression levels that were different from midparental values and outside the range of parental values than hybrids that do not exhibit heterosis. RESULTS:...
