Expression levels of DEGs of the auxin metabolism pathway. A Expression patterns of DEGs of the IAA biosynthesis and signaling pathway. B the contents of IAA. The significance of differences was assessed using the Student’s t-test. *p < 0.05, ** p < 0.01. C-J qRT-PCR analysis of the expression patterns of randomly selected IAA-related DEGs. Data are presented as the means ± SD of three technical replicates and three independent biological replicates
