Cys(2)/His(2) zinc-finger protein (C2H2-ZFP) is widely involved in the reproductive development of plants, but its role in pollen development is still elusive. Here, we identified a pollen-related C2H2-ZFP gene named as MALE FERTILITY-ASSOCIATED ZINC FINGER PROTEIN 1 (MAZ1), which was first isolated from Arabidopsis thaliana. MAZ1 showed a preferential expression pattern in early anther development. Its mutation resulted in aberrant primexine deposition at the tetrad stage, followed by a defective multiple-layer pattern of exine with irregular baculum and no tectum. Furthermore, microspore development was arrested, and no intine layer was formed. These developmental defects led to fertility reduction and pollen abortion. This study reveals the essential role of MAZ1 in pollen wall development. (C) 2019 Elsevier Inc. All rights reserved.
