Fig. 4From: Glycolate oxidase-dependent H2O2 production regulates IAA biosynthesis in riceChanges of IAA and Trp levels in glo1 and glo4 mutants. Germinated seeds were cultured under atmospheric and high CO2 conditions. The leaves of five-leaf stage rice seedlings were then detached for determining IAA (A) and Trp (B). Data are presented as means ± SD of three biological replications, *P < 0.05, **P < 0.01 according to Student’s t-testsBack to article page
