The original version of this article unfortunately contained some errors. The authors would like to make the following corrections to the article.

In the Abstract, ‘25 members were enhanced upon the development of superficial scald, while three in dehydroascorbate reductase (DHAR) class were downregulated in association with lower DHAR activity. In combination with the results of the impact of 1-MCP and MHO fumigation on the expression profile of PbrGSTs, PbrDHAR1, PbrDHAR2 and PbrDHAR4 were selected as the candidate gene involved in superficial scald development.’ should read:

“26 members were enhanced upon the development of superficial scald, while two in dehydroascorbate reductase (DHAR) class were downregulated in association with lower DHAR activity. In combination with the results of the impact of 1-MCP and MHO fumigation on the expression profile of PbrGSTs, PbrDHAR1 and PbrDHAR2 were selected as the candidate gene involved in superficial scald development.”

In the Results, ‘Of these, the expression of PbrGSTU1-8, PbrGSTU11-12, PbrGSTU16, PbrGSTU25-27, PbrGSTU29-32, PbrGSTF2, PbrGSTL1-5, and PbrGSTT1 were upregulated upon the development of superficial scald, while PbrDHAR1, PbrDHAR2, and PbrDHAR4 mRNAs showed an opposite behavior (Fig. 6 and Table S12).’, Paragraph 15, Sentences 2 should read:

“Of these, the expression of PbrGSTU1-8, PbrGSTU11-12, PbrGSTU16, PbrGSTU25-27, PbrGSTU29-32, PbrGSTF2, PbrGSTL1-5, PbrGSTT1, and PbrDHAR4 were upregulated upon the development of superficial scald, while PbrDHAR1 and PbrDHAR2 showed an opposite behavior (Fig. 6 and Table S12).”

In the Discussion, ‘Of these, the transcription levels of PbrGSTU1-8, PbrGSTU11-12, PbrGSTU16, PbrGSTU25-27, PbrGSTU29-32, PbrGSTF2, PbrGSTL1-5, and PbrGSTT1 were higher in fruit with superficial scald, while the expression of PbrDHAR1 and PbrDHAR2, and PbrDHAR4 were downregulated (Fig. 6 and Table S12). These results imply that individual PbrGST gene might be highly specific in their induction patterns (Qin et al. 2015).’ Paragraph 4, Sentences 2 should read:

“Of these, the transcription levels of PbrGSTU1-8, PbrGSTU11-12, PbrGSTU16, PbrGSTU25-27, PbrGSTU29-32, PbrGSTF2, PbrGSTL1-5, PbrGSTT1 and PbrDHAR4 were higher in fruit with superficial scald, while the expression of PbrDHAR1 and PbrDHAR2 were downregulated (Fig. 6 and Table S12). These results imply that individual PbrGST gene might be highly specific in their induction patterns (Qin et al. 2015).”

In the Discussion, ‘Thus, in combination with the results of Figs. 5 and 6, PbrDHAR1, PbrDHAR2 and PbrDHAR4 might participate in the development of superficial scald.’ Paragraph 5, Sentences 5 should read:

“Thus, in combination with the results of Figs. 5 and 6, PbrDHAR1 and PbrDHAR2 might participate in the development of superficial scald.”

In the Conclusion, ‘The expression of 25 PbrGST genes were enhanced upon superficial scald development, while three members in DHAR class was downregulated. In combination with the results of 1-MCP and MHO fumigation, PbrDHAR1, PbrDHAR2 and PbrDHAR4 might participate in the development of superficial scald through regulating redox balance.’ should read:

“The expression of 26 PbrGST genes were enhanced upon superficial scald development, while two members in DHAR class was downregulated. In combination with the results of 1-MCP and MHO fumigation, PbrDHAR1 and PbrDHAR2 might participate in the development of superficial scald through regulating redox balance.”

The expression data of Fig. 6 and Supplementary Material Table S12 have been corrected. The corrected Fig. 6 and Table S12 are presented here.

Alternation in the expression profiles of PbrGSTs in the pericarp of ‘Yali’ pear upon superficial scald development. a Transcriptome analysis of the PbrGSTs expression profile in different samples. Samples were taken after 180 days storage at − 0.5 ℃ + 7 days shelf life at 20 ℃. The genes are located on the right and the samples are indicated at the bottom of each column. The color scale represents normalized log 2-transformed (mean FPKM of the two biological replicates + 1), where red indicates a high level, green indicates a low level and black indicates a medium level. b qRT-PCR analysis of the mRNA contents of some genes (PbrGSTU1, PbrGSTL3, PbrGSTT1, PbrGSTZ2, PbrDHAR1, PbrGSTF2, PbrTCHQD1, and PbrEF1Bγ2). The expression level of PbrGSTU1 in No-SC sample was set as 1, and vertical bars labeled with the different letter are significantly different at p < 0.05 level using Duncan's multiple range test. Abbreviations are as follow: No-SC, fruit without superficial scald; SC, fruit with superficial scald
