A C2H2-type zinc finger protein TaZFP8-5B negatively regulates disease resistance.

ABSTRACT:

Background

Zinc finger proteins (ZFPs) are important regulators in abiotic and biotic stress tolerance in plants. However, the role of the ZFPs in wheat responding to pathogen infection is poorly understood.

Results

In this study, we found TaZFP8-5B was down-regulated by Puccinia striiformis f. sp. tritici (Pst) infection. TaZFP8-5B possesses a single C2H2-type zinc finger domain with a plant-specific QALGGH motif, and an EAR motif (LxLxL) at the C-terminus. The EAR motif represses the trans-activation ability of TaZFP8-5B. Knocking down the expression of TaZFP8 by virus-induced gene silencing increased wheat resistance to Pst, whereas TaZFP8-5B-overexpressing reduced wheat resistance to stripe rust and rice resistance to Magnaporthe oryzae, suggesting that TaZFP8-5B plays a
