Weighted gene co-expression network analysis unveils gene networks regulating folate biosynthesis in maize endosperm.

ABSTRACT: Folates are essential elements for human growth and development, and their deficiency can lead to serious disorders. Waxy maize is a rich source of folates; however, the regulatory mechanism underlying folate biosynthesis in the endosperm remains unclear. Here, we examined changes in the folate content of maize endosperm collected at 15, 18, 21, 24, and 27 days after pollination (DAP) using liquid chromatograph-mass spectrometry and identified genes related to folate biosynthesis using transcriptome sequencing data. The results showed that 5-methyl-tetrahydrofolate and 5,10-methylene tetrahydrofolate were the main storage forms of folates in the endosperm, and their contents were relatively high at 21-24 days. We also identified 569, 3183, 4365, and 5513 differentially expressed genes (DEG
