“…SPE is a special form of gene expression complementation between parents, which has been proven to be an important reason for the excellent performance of F1 hybrid traits [4,50]. In this study, the number of SPE circRNAs in the parents was much higher than that in their F1 hybrids, which is inconsistent with previous studies [10,34]. However, the number of SPE circRNAs of the F1 hybrids with high growth potential was higher than that of the F1 hybrids with low growth potential, especially for SPE-F circRNAs.…”

“…Only a small number of circRNAs (98-237) had significant differential expression, showing a non-additive effect (Figure 2A), indicating that circR-NAs of the F1 hybrids mainly show additive genetic effects. Luo et al found that linear and circular transcripts were mainly non-additive in the leaves of F1 hybrids and their parents of maize [10]. The proportion of additive expression of circRNAs in the F1 hybrids with high growth potential was 91.38-95.44%, and that of non-additively expressed circR-NAs was 4.56-8.62%.…”

“…The difference in the expression levels of circRNAs between the F1 hybrids and their parents is believed to be an important reason for the formation of heterosis, which is worthy of in-depth study [4,10]. Non-additive expression of circRNAs is represented by differentially expressed circRNAs (DECs) between the F1 hybrids and the middle parent value (MPV), which has been proven to be an important reason for the difference between the F1 hybrids and their parents [20].…”

“…With the development of transcriptomics, epigenetics, proteomics, and metabonomics, many studies have attempted to explain the formation of heterosis at the molecular level. mRNAs [25], miRNA [26][27][28], long noncoding RNAs (lncRNAs) [29,30], and circRNAs [4,10] have been confirmed to be related to plant heterosis. The difference in gene expression between parents and their offspring in plants can partly explain the formation of heterosis [20,21,31,32].…”

Circular RNAs (CircRNAs) regulate plant growth and development; however, their role in poplar heterosis is unclear. We identified 3722 circRNAs in poplar leaves, most of which were intergenic (57.2%) and exonic (40.2%). The expression of circRNAs in F1 hybrids with high growth potential was higher than that in those with low growth potential. Non-additive expression of circRNAs and single-parent expression of circRNAs (SPE-circRNAs) might regulate poplar heterosis through microRNA sponging and protein translation, respectively. DECs among F1 hybrids with different growth potentials might regulate the growth potential of poplar via microRNA sponging. Correlation analysis between circRNA expression and its parent gene expression showed that SPE-M circRNA (circRNAs expressed by male parent only) might regulate poplar heterosis by inhibiting parent gene expression, while other circRNAs might regulate poplar heterosis by enhancing parent gene expression. Weighted correlation network analysis of gene/circRNA expression showed that circRNAs mainly regulate poplar heterosis via carbohydrate metabolism, amino acid metabolism, energy metabolism, and material transport. In addition, we identified seven circRNAs that positively or negatively regulate poplar heterosis. Thus, non-additively expressed circRNAs and SPE circRNAs are involved in regulating poplar heterosis, and DECs among F1 hybrids with different growth potentials were involved in regulating poplar growth potential.
