Figure 1 Asymmetrical Distribution of the GH3 Family Genes in the Chinese Spring Genome. A, B, and D represent the three subgenomes in allohexaploid wheat. Red lines indicate triplet homoeologs that are present on all three homoeologous chromosomes. Purple lines indicate duplet homoeologs that are present on two homoeologous chromosomes. Black lines indicate singletons that are present only on one homoeologous chromosomes. Genes are positioned according to their chromosome arm locations and are not in their exact positions and order on the chromosomes. See Supplemental Table 1 for annotation information.

Figure 2 A Model to Summarize the Molecular Mechanisms that May Be Involved in Homoeolog Expressions Leading to Non-additive Gene Expression and Parental Expression Level Dominance Genes that May Be Relevant to the Growth Vigor and Enhanced Adaptation in Nascent Allohexaploid Wheat. (A) siRNA regulation module. Genome stabilization by siRNA mediated chromatin modification (a), gene expression (b, c), and TAG silencing (d). (B) miRNA regulation module. Homoeolog-specific cleavage by diverged miRNAs and their differential expressions. (C) Regulation of protein-coding gene expressions and their distinct functions (development, growth vigor, and adaptation) in nascent allohexaploid wheat. The two red bars represent gene expression levels in the allohexaploid progeny. The question mark in the middle indicates unknown cis and trans mechanisms for protein-coding gene regulation.
