Expression data from Arabidopsis Col, C24 and their F1 hybrid at 15 DAS

To obtain new insights for heterosis mechanisms in Arabidopsis, transcript profiling of arabidopsis F1 hybrid and their parentral lines was obtained from Affymetrix GeneChips ATH array. The microarray analysis exhibited that there were 44 up-regulated and 12 down-regulated genes with more than a 1.5-fold changes in the profiles of F1 hybrid against those of each parent. Gene ontology analyses highlighted up-regulated genes as organic nitrogen-related in the F1 hybrid. Whole rosette of Col, C24, and F1 hybrid(C24xCol) with three replications.
