Figure 7. Drought stress induces alterations in IAA, ABA and JA metabolism and signaling in tomato anthers. (A) Distribution (%) of different phytohormones metabolic and signaling DEGs in tomato anthers. (B) Contents of IAA, ABA and JA in anthers 4 d after DS. (C) Expression analysis of genes involved in IAA (red titles), ABA (black titles) and JA (blue titles) metabolism and /or signaling in DS anther based on RNA-Seq data. Values are means ±SD (n = 3 replications, 24 plants each). * p<0.05; **p <0.01; ***p < 0.001 (t-test).
