Comparison of dynamic 3D chromatin architecture uncovers heterosis for leaf size in Brassica napus.

ABSTRACT:

Introduction

Heterosis is the major event driving plant development and promoting crop breeding, but the molecular bases for this phenomenon remain elusive.

Objectives

We aim to explore the effect of three-dimensional (3D) chromatin architecture on the underlying mechanism of heterosis.

Methods

Here, we constructed the North Carolina II (NC-II) population to select superior and inferior heterosis sets by comparing mid-parent heterosis (MPH) in Brassica napus. To decipher the impact of 3D chromatin architecture on the underlying mechanism of heterosis, we combined genetics, transcriptomics and 3D genomics approaches.

Results

We suggest that F1 hybrids with superior heterosis tend to contain more transcriptionally active A compartments compared with F1 hybrids wi
