Fig. 7From: Eriodictyol can modulate cellular auxin gradients to efficiently promote in vitro cotton fibre developmentFibre development was efficiently promoted in the presence of ERI. (a) Quantification of IAA in control and ERI treatments after 1, 5 and 10 days. (b) Log2 values of the ERI/control ratios for differentially expressed auxin signaling pathway genes (AUX1, AUXIAA, GH3 and SAUR) based on FPKM values are plotted as a heat map. (c) Four different chemical combinations (IAA + GA3, GA3, IAA, IAA + GA3 + TIBA) were used as treatments in the control (0 μM) and ERI (20 μM). The white line represents the scale bar, 10 mm. (d) Fibre length and (e)TFU were measured in control and ERI ovules after 10 days for the four treatments. Significant differences are denoted as * at 5% and ** at 1% significance, while non-significant differences are indicated by nsBack to article page
