In the original article, there was a mistake in Table 3 as published. In original Table 3, four aquaporin genes (GRMZM2G041980, GRMZM2G392975, GRMZM2G126582, GRMZM2G081843) were repeated two times, and we neglected to include several upregulated glycosyltransferase genes (GRMZM2G120016, GRMZM5G834303). The corrected Table 3 appears below.

In the original article, there was an error. The reads from the HiII embryo samples were incorrectly presented as “7,432,161–15,904,122”. The correct reads from the HiII embryo samples should be “7,432,161–15,881,554” as shown in Table 1.
A correction has been made to (Results), (Maize Embryo Transcriptome Profiling), (Paragraph 1):
To investigate the mechanism of cysteine-related transformation efficiency improvement, we performed transcriptome analysis of the maize embryos cultured on the medium with or without cysteine. The experiment was performed with four independent biological replicates. We obtained 7,432,161–15,881,554 reads from the HiII embryo samples and more than 78.73% of the reads were mapped to the B73 reference genome. We obtained 20,119,176–24,789,278 reads from the inbred line Z31 embryo samples and 73.66% of the reads were mapped to the B73 reference genome (Table 1). Maize has ~ 30,000 genes and the sequencing depth we acquired was enough for subsequent analysis. The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way.
