The triploid block, which prevents interploidy hybridizations in flowering plants, is characterized by a failure endosperm development, arrest embryogenesis, and seed collapse. Many genetic components of lethality have been successfully identified the model plant Arabidopsis thaliana, most notably paternally expressed genes (PEGs), are upregulated tetraploid with paternal excess. Previous studies shown that epigenome key determinant block response, as loss DNA methylation diploid pollen...
Hybridization of closely related plant species is frequently connected to endosperm arrest and seed failure, for reasons that remain be identified. In this study, we investigated the molecular events accompanying failure in hybrids pair Capsella rubella C. grandiflora. Mapping QTL underlying cause hybrid incompatibility identified three were close pericentromeric regions. We whether there are specific changes heterochromatin associated with interspecific hybridizations found a strong...
Hybrid seed failure arising from wide crosses between plant species is a recurring obstacle in breeding, impeding the transfer of desirable traits. This postzygotic reproductive barrier primarily occurs endosperm, tissue that nourishes embryo and functions similarly to placenta mammals. We found incompatible seeds show loss DNA methylation chromatin condensation similar lacking maternal RNA polymerase IV activity. similarity linked decrease small interfering RNAs endosperm (sirenRNAs),...
<title>Abstract</title> Hybrid seed failure arising from wide crosses between plant species is a recurring obstacle in breeding, impeding the transfer of desirable traits. This postzygotic reproductive barrier primarily occurs endosperm, dosage-sensitive tissue that nurtures embryo and functions analogously to placenta mammals. Here, we show endosperm incompatible seeds loses DNA methylation chromatin condensation, resembling depleted for maternal RNA Polymerase IV (Pol IV) function....
Abstract Hybridization of closely related plant species is frequently connected to endosperm arrest and seed failure, for reasons that remain be identified. In this study, we investigated the molecular events accompanying failure in hybrids pair Capsella rubella C. grandiflora . Mapping QTLs underlying cause hybrid incompatibility revealed three were close pericentromeric regions. This prompted us investigate whether there are specific changes heterochromatin associated with interspecific...
Abstract The “triploid block” prevents interploidy hybridizations in flowering plants, and is characterized by failure endosperm development, arrest embryogenesis, seed collapse. Many genetic components of triploid lethality have been successfully identified the model plant Arabidopsis thaliana , most notably paternally expressed imprinted genes (PEGs) that are up-regulated tetraploid with paternal excess. Previous studies shown epigenome a key determinant block response, as loss DNA...
