dc.description.abstract | <p>Maize (<em>Zea mays</em>) displays an exceptional level of structural genomic diversity, which is likely unique among higher eukaryotes. In this study, we surveyed how the genetic divergence of two maize inbred lines affects the transcriptomic landscape in four different primary root tissues of their F1-hybrid progeny. An extreme instance of complementation was frequently observed: genes that were expressed in only one parent but in both reciprocal hybrids. This single-parent expression (<a href="http://www.plantcell.org/content/26/10/3939#def-3" id="x-x-x-xref-def-3-1">SPE</a>) pattern was detected for 2341 genes with up to 1287 <a href="http://www.plantcell.org/content/26/10/3939#def-3" id="x-x-x-xref-def-3-2">SPE</a> patterns per tissue. As a consequence, the number of active genes in hybrids exceeded that of their parents in each tissue by >400. <a href="http://www.plantcell.org/content/26/10/3939#def-3" id="x-x-x-xref-def-3-3">SPE</a>patterns are highly dynamic, as illustrated by their excessive degree of tissue specificity (80%). The biological significance of this type of complementation is underpinned by the observation that a disproportionally high number of <a href="http://www.plantcell.org/content/26/10/3939#def-3" id="x-x-x-xref-def-3-4">SPE</a> genes (75 to 82%) is nonsyntenic, as opposed to all expressed genes (36%). These genes likely evolved after the last whole-genome duplication and are therefore younger than the syntenic genes. In summary, <a href="http://www.plantcell.org/content/26/10/3939#def-3" id="x-x-x-xref-def-3-5">SPE</a> genes shape the remarkable gene expression plasticity between root tissues and complementation in maize hybrids, resulting in a tissue-specific increase of active genes in F1-hybrids compared with their inbred parents.</p> | |
