Transcriptome data of maize under cold stress
The seeds of 14 varieties of maize were soaked in warm water for 24 h, planted in sand beds, and cultured in light incubators at 25 with a photocycle of 12/12 h. When the two leaves of seedlings were at one stage, the treatment group was subjected to low-temperature stress at 5 in the light incubator, removed after 48h, and restored to growth at 25 for 12h under light for 24h. The control group grew normally in a 25 light incubator. The experiment was repeated 3 times with 50 plants in each replicate. After treatment, the survival rate of seedlings and stress level at seedling stage were investigated, and the average value of 3 replicates was used as the statistical unit.
