transcriptomic of chromosome doubling of Z58 haploid

The immature haploid embryos of the maize inbred line Zheng58 treated with amiprophos-methyl (APM) or colchicine were used to analyze transcriptomic and metabolomic changes, 75 and 60 differential expressed metabolites (DEMs) were identified between control treatment, respectively. Most differentially expressed genes (DEGs) related to artificial chromosome doubling were down regulated; these were mainly involved in mitosis process. Both DEMs and DEGs co-expression analyses showed that, compared to controls, zeatin biosynthesis and cofactor and vitamin metabolism were significantly enriched in both APM and colchicine treatments. The data have already been deposited in the NCBI Sequence Read Archive, accession number: PRJNA976036 (https://www.ncbi.nlm.nih.gov/sra/PRJNA976036).
