ZmMYB31, a R2R3-MYB transcription factor in maize, positively regulates the expression of CBF genes and enhances resistance to chilling and oxidative stress

Maize (Zea mays L.) is an important model plant with an important role in agriculture and national economies all over the world. The optimum growth temperature of maize is between 25 and 28 °C. At temperatures below 12 °C, maize is vulnerable to damage by chilling stress. MYB transcription factors play important roles in plants’ response to low temperature stress. Maize ZmMYB31 encodes a R2R3-MYB transcription factor, ZmMYB31, which localized in...
