Rhizosphere priming of two near-isogenic wheat lines varying in citrate efflux under different levels of phosphorus supply

This is the authors' abstract. We don't add key points for this paper.

While high P supply increased microbial growth and RPE possibly due to higher total root exudation, citrate efflux from the root might have facilitated the liberation of mineral-bound C, leading to the higher RPE under Egret-Burke TaMATE1B. Mineral dissolution may be an important process that regulates RPE and should be considered in future RPE research.
