TranscriptomicsAlterations to hormone regulated defense and stress response networks contribute to the greater growth of Arabidopsis F1 hybrids
Heterosis, or hybrid vigor, has been exploited in agriculture to deliver increases in crop yields for over a century, yet the molecular basis is not well understood We have studied the transcriptomes of 15 day old seedlings from intraspecific Arabidopsis hybrids with varying levels of heterosis and...

TranscriptomicsHybrid Mimics and Hybrid Vigor in Arabidopsis (F4 data)
F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor which form the basis of the hybrid seed industry. The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants which have a F1€“like phenotype, we have by...

TranscriptomicsHybrid Mimics and Hybrid Vigor in Arabidopsis (F6 data)
F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor which form the basis of the hybrid seed industry. The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants which have a F1 –like phenotype, we have ...

TranscriptomicssRNA populations of 2 week old seedlings from Arabidopsis ecotypes C24, Ler, and their two reciprocal F1 hybrids
We examined sRNA populations in the Arabidopsis ecotypes C24, Landsberg erecta (Ler), and their reciprocal hybrids which display strong intra-species heterosis. The parental ecotypes had significant differences in their sRNA epigenomes and associated methylation profiles. The hybrids differed grea...
