Abstract

AN1/A20-like Zinc finger family proteins are evolutionarily conserved regulatory components in eukaryotic signaling circuits. In Arabidopsis thaliana, the AN1/A20 Zinc finger family is encoded as 14 members in the genome and collectively referred to as stress-associated proteins (SAPs). Here we described AtSAP5 localized to the nucleus, and played a role in heat-responsive gene regulation together with MBF1c. Seedling survival assay of sap5 and mbf1c demonstrated consistent effects of AtSAP5 and MBF1C in response to two-step heat treatment, supporting their function in heat stress tolerance. Our findings yield an insight in A20/AN1-like Zinc finger protein AtSAP5 functions in plant adaptability under high temperature.
