arabidopsis heterosis project
Heterosis refers to the phenomenon that progeny of intra- or inter- species cross exhibit greater biomass, speed of development, and  fertility than both parents. To understand the mechanisms of heterosis,  we analyzed transcriptome, sRNAome and methylome profiles from 2 weeks  old seedlings of two Arabidopsis thaliana accessions and their  reciprocal hybrids. Subsequently, we compared these data of F1 hybrid  and their parents and discussed whether transcriptional and epigenetic  variation between F1 hybrid and their parents were associated with  heterosis.
