Other claims from this paper (9)
- Observation ZmHSF21 is expressed in maize leaves and silks at relatively high levels, and low in roots and stalks.
- Intervention effect Heat treatment significantly up-regulated ZmHSF21 expression level in maize leaves.
- Intervention effect Overexpression of ZmHSF21 in Arabidopsis significantly improved seed germination frequency and plant survival rate under heat stress.
- Intervention effect ZmHSF21 overexpressors under heat stress had increased peroxidase, superoxide dismutase and catalase activities compared with wild-type plants.
- Intervention effect ZmHSF21 overexpressors under heat stress had decreased reactive oxygen species accumulation compared with wild-type plants.
- Intervention effect ZmHSF21 overexpression promoted the transcriptional level of AtAPX2, AtGolS1 and several AtHSPs in Arabidopsis.
- Recommendation ZmHSF21 can be applied to develop maize varieties with high-temperature tolerance for more yield.
- Observation A Class C heat shock factor, ZmHSF21, was identified from maize leaves.
- Observation ZmHSF21 encodes a putative protein of 388 amino acids.
