Root length, shoot length, and relative expression of selected OsPIN genes in rice seedlings (Oryza sativa L. cv. Nagdong) grown in supplemented agar medium under gravistimulation. (a) Roots and shoots length (b). Relative expression of selected OsPIN genes in the root, root shoot junction (rsj), and shoot. The experiment was repeatedly conducted under controlled greenhouse conditions without any treatment. Vertical bars indicate mean ± standard error of the mean (n = 3). Asterisks in the vertical bar indicate significant difference at ^*p < 0.05, ^**p < 0.01, ^***p < 0.001 compared to controls.
