Phosphorus (P) deficiency and aluminum (Al) toxicity often coexist are two major limiting factors for crop production in acid soils. The purpose of this study was to characterize the function GmBBE-like43, a berberine bridge enzyme-like protein-encoding gene, soybean (Glycine max) adaptation Al low P stresses. Present quantitative real-time PCR (qRT-PCR) assays confirmed phosphate (Pi)-starvation enhanced Al-stress up-regulated expression pattern GmBBE-like43 roots. Meanwhile, GmBBE-like43-GFP chimera both common bean hairy roots tobacco leaves demonstrated its cell wall localization. Moreover, transgenic Arabidopsis revealed promoting root growth under GmBBE-like43-overexpression also resulted more H2O2 on surface with oligogalacturonides (OGs) application antagonized effects SAUR-like genes. Taken together, our results suggest that might be involved soybean's coordinated Pi starvation through modulation OGs-oxidation wall.
