Figure 6.
Analysis of root morphology in the 3 RNAi lines and wild plants grown under low Pi (10 µM) on hydroponics. Whole root images showing the lateral root formation in wild type and 3 RNAi lines grown after 4 weeks (A) (bar = 1 cm), root hair images of wild type plant and 3 RNAi lines after 4 weeks of growth (B), measurement of lateral root density per cm of root and root hair density per 10 µM of root in seedlings of wild type plants and 3 RNAi lines grown under low Pi on hydroponics for 4 weeks (C). Values are expressed as mean ± SD of 3 replicates (n = 3). Values followed by the same letter are not significantly different (P > 0.001) (separately for lateral root density shoot and root hair density).
