摘要: Sorghum is one of the five most productive crops worldwide, but its yield is seriously limited by phosphate (Pi) availability. Although inorganic Pi signalling is well studied in Arabidopsis and rice, it remains largely unknown in sorghum. The sorghum sbpho2 mutant was identified, showing leaf necrosis and short roots. Map-based cloning identified SbPHO2 as Sobic.009G228100, an E2 conjugase gene that is a putative orthologue of the PHO2 genes in rice and Arabidopsis, which play important roles in Pi signalling. Pi starvation experiments and transformation of SbPHO2 into the rice ospho2 mutant further revealed that SbPHO2 is likely involved in Pi accumulation and root architecture alteration in sorghum. qRT-PCR results showed that SbPHO2 was expressed in almost the entire plant, especially in the leaves. Furthermore, some typical Pi starvation-induced genes were induced in sbpho2 even under Pi-sufficient conditions, including Pi transporters, SPXs, phosphatases and lipid composition alteration-related genes. In addition to P accumulation in the shoots of sbpho2, concentrations of N, K, and other metal elements were also altered significantly in the sbpho2 plants. Nitrate uptake was also sup-pressed in the sbpho2 mutant. Consistent with this finding, the expression of several nitrate-, potassium-and other metal element-related genes was also altered in sbpho2. Furthermore, the results indicated that N -depen-dent control of the P starvation response is regulated via SbPHO2 in sorghum. Our results suggest that SbPHO2 participates in the regulation of the absorption of multiple nutrients, although PHO2 is a crucial and conserved component of Pi starvation signalling.
