摘 要：A colchicine-induced autotetraploid grapevine exhibiting potentially valuable agronomic traits for grape production and breeding,including self-pruning,was *** study investigated DNA methylation variation and its role in gene expression during self-pruning in the autotetraploid *** used RNA-Seq to estimate differentially expressed genes between diploid and autotetraploid grapevine shoot *** genes showing increases in the autotetraploid were mainly related to stress response pathways,whereas those showing decreases in the autotetraploid were related to biological metabolism and ***-genome bisulfite sequencing was performed to produce single-base methylomes for the diploid and autotetraploid *** between the methylomes revealed that they were conserved in CG and CHG *** the autotetraploid grapevine,hypodifferentially methylated regions(DMRs)and hyper-DMRs in the gene body increased or decreased gene expression,*** results indicated that a hypo-DMR in the ACO1 gene body increased its expression and might promote *** study reports that hypo-DMRs in the gene body increase gene expression in plants and reveals the mechanism underlying the changes in the modifications affecting gene expression during genome ***,our results provide valuable information for understanding the relationships between DNA methylation,gene expression,and autotetraploid breeding in grape.
