Figure 4. PHT5 proteins regulate the storage of vac-Pi and cyt-Pi homeostasis.

Figure 4

31P-MRS analysis of vac-Pi and cyt-Pi (a), Pi distribution between the vacuole and the cytoplasm, and the calculated vac-Pi and cyt-Pi levels (b) of WT, pht5;1-2, pht5;1-2 pht5;2 pht5;3, p35S:PHT5;2-HA, p35S:PHT5;1-GFP and pho2 seedlings grown under Pi-sufficient conditions. ref, methylene diphosphonate (MDP). Asterisks indicate a significant difference compared with WT, *P<0.05 and **P<0.01, Student's t-test, ±s.d.; error bar, s.e. The numbers of biological replicates (n) are indicated in b. Results were combined from three to six independent experiments.
