Abstract

Background. The yield of maize crop is influenced seriously by heat waves. Plant heat shock transcription factors (Hsfs) play a key regulatory role in heat shock signal transduction pathway. Method. In this study, a new heat shock transcription factor gene, ZmHsf01 (accession number: MK888854) , was cloned from maize young leaves using homologous cloning method. The transcriptional level of ZmHsf01 were detected by qRT-PCR in different tissues or under heat shock, abscisic acid (ABA) and hydrogen peroxide (H 2 O 2) treatment. The transgenic yeast and Arabidopsis were used to study the gene function of ZmHsf01. Result. The coding sequence (CDS) of ZmHsf01 was 1176 bp and
