Extended Data Fig. 8: Al-induced PP2CH1 expression is STOP1-independent.
(a, b) Expression analysis of PP2CH1/2 in 1-week-old WT and stop1 mutant roots under control and 75 μM Al (1 h, 2 h) treatments (n = 3 biological repeats). (c) FLAG-PP2CH1 proteins in 35S:FLAG-PP2CH1 root apices with or without 100 µM Al, 100 µM La and 100 µM Fe treatments for 1 h. Protein levels were detected with α-Flag antibody. Error bars represent means ± SD. All data were analyzed by two-tailed unpaired t test (a, b).
