Genome-Wide Dosage-Dependent and -Independent Regulation Contributes to Gene Expression and Evolutionary Novelty in Plant Polyploids

(Submitter supplied) Polyploidy provides evolutionary and morphological novelties in many plants and some animals. However, the role of genome dosage and composition in gene expression changes remains poorly understood. Here, we generated a series of resynthesized Arabidopsis tetraploids that contain 0-4 copies of Arabidopsis thaliana and Arabidopsis arenosa genomes and investigated ploidy and hybridity effects on gene expression. more...

Perturbation of parent-specific gene expression during interspecific hybridization

(Submitter supplied) Interspecific hybridization often induces epigenetic remodeling that leads to transposon activation, gene expression changes, and loss of imprinting. These genomic changes can be deleterious and lead to postzygotic hybrid incompatibility. In Arabidopsis, loss of genomic imprinting of PHERES1 and presumed failure of Polycomb Repressive Complex is partially responsible for seed inviability observed in A. more...

Early disruption of maternal-zygotic interaction and activation of defense-like responses in Arabidopsis interspecific incompatibility

(Submitter supplied) Seed death resulting from hybridization between Arabidopsis thaliana and Arabidopsis arenosa has complex genetic determination, and involves deregulation 5-8 days after pollination (DAP) of AGAMOUS-LIKE genes (AGLs) and retroelements. To identify causal mechanisms, we compared 3 DAP transcriptomes of compatible and incompatible hybrids and parents at 3 DAP. Hybrids misexpressed endosperm and seed coat regulators, and hyperactivated genes encoding ribosomal, photosynthetic, stress-related and immune response proteins. more...
