Ceriporia lacerata HG2011 enhances P mobilization and wheat agronomic performance irrespective of P fertilization levels

Abstract

Abstract Aims To identify soil phosphorus (P) mobilization and wheat agronomic performance in response to the P mobilizer Ceriporia lacerata HG2011 could provide a new strategy for improving fertilizer P efficiency in wheat cultivation. Methods and Results Liquid culture showed that C. lacerata HG2011 converted Ca3(PO4)2, FePO4, AlPO4, phytate, lecithin and ribonucleic acid into soluble inorganic P, which was stimulated by ammonium and urea but less influenced by P supply. In the incubation experiment, this fungus colonized on wheat roots, and mobilized P in the soils regardless of Olsen P levels. The efflux of protons, organic acids and phosphatase could be involved in insoluble P mobilization. In the greenhouse pot experiment, C. lacerata HG2011 increased soil Olsen P under different P fertilization levels, improved wheat P uptake by 15.39%–28.70%, P fertilizer use efficiency by 4.26%–13.04% and grain yield by 12.24%–22.39%. Conclusions Ceriporia lacerata HG2011 was able to colonize on wheat roots, mobilize P in soils and improve wheat agronomic performance irrespective of P fertilization levels. Significance and Impact of the Study Ceriporia lacerata HG2011 could be used to enhance the quality of compost or as a bio-fertilizer for P mobilization in modern sustainable agriculture.
