Maize (Zea mays L.) is an important food crop planted across the world, and low-temperature stress can affect maize germination. Alternative splicing (AS) widely present in plants under abiotic stress; however, response of AS to remains unclear. In this study, a genome-wide analysis during low temperatures was performed. events were distributed on each chromosome, approximately 2.05-2.09 per gene. Seven genes only had low-temperature-resistant inbred lines. A total 278 KEGGs 46 GOs enriched based overlapping genes, which associated with hormone oxidoreductase activity. The mutant used verify function gene ZmWRKY48, RGR, RSL, RRL, RRSA decreased by 15.16%-19.87% compared normal line. These results contribute subsequent regulatory mechanism stress.
