Figure 2.
The effect of Zhongmu No. 1 cultivar alfalfa infested by either R-aphids or S-aphids on the subsequent activities of the JA plant hormone (a) and SA plant hormone (b) signaling pathways and expression of the AOS gene (c), the LOX gene (d), the ICS gene (e), and the PAL gene (f). The different lowercase letters indicate significant differences in signal hormone contents and gene expression between Zhongmu No. 1 infested by R-aphids and S-aphids (p < 0.05; Tukey’s HSD).
