Genome-wide identification of the GST reveals ZmGST1 enhances the resistance to Exserohilum turcicum in maize.

ABSTRACT:

Background

Northern corn leaf blight is caused by Exserohilum turcicum and poses a significant threat to maize yields. Therefore, it is of vital importance to explore disease-resistant genes and cultivate disease-resistant varieties. Glutathione S-transferases (GSTs) play an important role in plant defense reactions. We previously found that GST genes are significantly regulated in maize after infection with E. turcicum in a comparative RNA-seq transcriptome study, however, the function of GSTs in resisting NCLB remains unclear.

Results

In this study, 31 ZmGST genes were identified in the maize genome and were classified into the tau, phi, and zeta classes based on phylogenetic analysis. Analysis of the exon-intron structure of the ZmGST genes revealed that the number of exo
