title: Expression of plant genes for arbuscular mycorrhiza-inducible phosphate transporters and fungal vesicle formation in sorghum, barley, and wheat roots.
abstract: Sorghum shows strong growth stimulation on arbuscular mycorrhizal (AM) symbiosis, while barley and wheat show growth depression. We identified the AM-inducible phosphate transporter genes of these cereals. Their protein products play major roles in phosphate absorption from arbuscules, intracellular fungal structures. Unexpectedly, barley and wheat expressed the AM-inducible genes at high levels. Hence the cause of their growth depression appears to be unrelated to the transcription of these genes. Notably, fungal vesicles were formed significantly more in barley and wheat than in sorghum. This study yielded new clues for investigation of the mechanism underlying these various responses.
