Relative expression of OsLPR3/5 and total P concentration in split-root experiment. Intact roots of rice seedlings were divided into two halves with one half placed in 300 μM Pi (sp + P) and another half in 0 μM Pi (sp -P). As controls, both halves were grown under 300 μM Pi (c + P) and 0 μM Pi (c -P). a qRT-PCR was used for determining the relative expression levels of OsLPR3/5 in the roots. Actin was used as an internal control. b Total P content. Values are means ± SE (n = 3) with different letters indicating values that differ significantly (P < 0.05)
