Abstract
Rhizosphere acidification is a general response to Pi deficiency especially in dicotyledonous plants However the signaling pathway underlying this process is still unclear Here we demonstrate that miR156 is induced in the shoots and roots of wild type Arabidopsis plants during Pi starvation The rhizosphere acidification capacity was increased in 35SMIR156 miR156 overexpression plants but was completely inhibited in 35SMIM156 target mimicry plants Both 35SMIR156 and 35SMIM156 plants showed altered proton efflux and H+ATPase activity In addition significant upregulation of H+ATPase activity in 35SMIR156 roots coupled with increased citric acid and malic acid exudates was observed qRTPCR results showed that most H+ATPase and PPCK gene transcript levels were decreased in 35SMIM156 plants which may account for the decreased H+ATPase activity in 35SMIM156 plants MiR156 also affect the root architecture system Collectively our results suggest that miR156 regulates the process of rhizosphere acidification in plantsWe thank Professor Jiawei Wang for providing the 35SMIR156 and 35SMIM156 seeds We also thank Dr Shuping Xing for providing the PromiR156aGUS and PromiR156dGUS seeds This work was supported by the National Natural Science Foundation of China 31371426 31570263
