Key messageThe present study identified several important candidate Pi regulation genes of maize and provides a better understanding on the generation ofPHRgenes in gramineous plants.AbstractPlants have evolved adaptive responses to cope with low phosphate (Pi) soils. The previous studies have indicated that phosphate starvation response (PHR) genes play central roles in regulating plant Pi starvation responses. However, the investigation ofPHRfamily in gramineous plants is limited. In this study, we identified 64PHRgenes in four gramineous plants, including maize, rice, sorghum, and brachypodium, and conducted systematical analyses on phylogenetic, structure, collinearity, and expression pattern of thesePHRgenes. Genome synteny analysis revealed that a number ofPHRgenes were present in the corresponding syntenic blocks of maize, rice, sorghum, and brachypodium, indicating that large-scale duplication events contributed significantly to the expansion and evolution ofPHRgenes in these gramineous plants. Gene expression analysis showed that manyPHRgenes were expressed in various tissues, suggesting that these genes are involved in Pi redistribution and allocation. In addition, the expression levels ofPHRgenes from maize and rice under low Pi stress conditions revealed that somePHRs may play an important role in Pi starvation response. Our results provided a better understanding on the generation ofPHRgenes in gramineous plants and identified several important candidate Pi regulation genes of maize.
