The AP2/ERF transcription factors play crucial roles in plant growth, development and responses to biotic abiotic stresses. A total of 119 genes (JcAP2/ERFs) have been identified the physic nut genome; they include 16 AP2, 4 RAV, 1 Soloist, 98 ERF genes. Phylogenetic analysis indicated that AP2 could be divided into 3 subgroups, while classed 11 groups or 43 subgroups. are non-randomly distributed across linkage genome retain many duplicates which arose from ancient duplication events. expression patterns several JcAP2/ERF showed differences among four tissues (root, stem, leaf, seed), 38 responded at least one stressor (drought, salinity, phosphate starvation, nitrogen starvation) leaves and/or roots according digital gene tag data. JcERF011 was downregulated by salinity stress roots. Overexpression rice plants increased its sensitivity stress. levels salt tolerance-related were impaired JcERF011-overexpressing under
