      abstract     = {Heterosis-associated cellular and molecular processes were
                      analyzed in seeds and seedlings of Arabidopsis thaliana
                      accessions Col-0 and C24 and their heterotic hybrids.
                      Microscopic examination revealed no advantages in terms of
                      hybrid mature embryo organ sizes or cell numbers. Increased
                      cotyledon sizes were detectable 4 days after sowing. Growth
                      heterosis results from elevated cell sizes and numbers, and
                      is well established at 10 days after sowing. The relative
                      growth rates of hybrid seedlings were most enhanced between
                      3 and 4 days after sowing. Global metabolite profiling and
                      targeted fatty acid analysis revealed maternal inheritance
                      patterns for a large proportion of metabolites in the very
                      early stages. During developmental progression, the
                      distribution shifts to dominant, intermediate and heterotic
                      patterns, with most changes occurring between 4 and 6 days
                      after sowing. The highest incidence of heterotic patterns
                      coincides with establishment of size differences at 4 days
                      after sowing. In contrast, overall transcript patterns at 4,
                      6 and 10 days after sowing are characterized by intermediate
                      to dominant patterns, with parental transcript levels
                      showing the largest differences. Overall, the results
                      suggest that, during early developmental stages,
                      intermediate gene expression and higher metabolic activity
                      in the hybrids compared to the parents lead to better
                      resource efficiency, and therefore enhanced performance in
                      the hybrids.},
