Two Aux/IAA genes ( DoIAA5 , 12 ) displayed an increasing trend from S1 to S3, and were negatively correlated ( r < -0.5, p < 0.05) with IAA content.
Two Aux/IAA genes ( DoIAA5 , 12 ) displayed an increasing trend from S1 to S3, and were negatively correlated ( r < -0.5, p < 0.05) with IAA content.
Endogenous IAA content showed a decreasing trend from S1 to S3 [ 20 ], with most of the 14 Aux/IAA genes ( DoIAA1 , 2 , 6 , 7 , 9 , 10 , 13 , 14 ) exhibiting a decreasing trend and a positive correlation ( r > 0.7, p < 0.05) with IAA content, suggesting their important roles in IAA metabolism.
