OsPIN1b regulates leaf inclination by activating BR and auxin signaling. (A) qRT-RCR analysis of the OsPIN1b expression under BR and IAA treatments with different time. The data are mean ± SD (n = 3), ** indicate significant difference at p < 0.01 (Student’s t-test). (B) The expression level of genes related to biosynthesis and signal transduction of BR and auxin in rice lamina joints of WT/NIP, ospin1b-1, ospin1b-2, OE-OsPIN1b-1, and OE-OsPIN1b-2 by qRT-RCR. OsACTIN was used as an internal control. The data are mean ± SD (n = 3), * indicates significant difference at p < 0.05, and ** indicates statistical significance at p < 0.01 (Student’s t-test).
