Pervasive under-dominance in gene expression as unifying principle of biomass heterosis in Arabidopsis
Yuan et al. (2022) bioRxiv 2022.03.03.482808
Heterosis, the generally superior performance in hybrids compared to their inbred parents, is one of the most enigmatic biological phenomena. Many … Read the rest
Under Aim 1 of our ERC-SyG project PATHOCOM, we are generating foundational data, by characterizing the intra- and interspecific diversity as well as abundance of pathobiota and commensal microbiota across multiple populations of A. thaliana in three regions in … Read the rest
