The gene expression of the zinc finger protein transcription factor zmzfp69 mutant of the maize inbred line and the control B73 under low-temperature stress at the seedling stage

C2H2 type (ZFP type) zinc finger protein can significantly enhance the cold tolerance of plants by directly regulating the downstream cold-related genes of plants. We confirmed through phenotypic and physiological experiments that the zmzfp69 mutant material has a stronger low-temperature resistance compared with the control B73. Therefore, we selected the mutant material (zmzfp69) and the control material (CK), and conducted low-temperature treatment at 4 ° C during the three-leaf stage. The sampling time was 0/24h/48h, and transcriptome sequencing was repeated three times for each sample to provide data for finding the mechanism of low-temperature stress at the maize seedling stage.
