Fig. 6From: Hydrogen peroxide is involved in hydrogen sulfide-induced lateral root formation in tomato seedlingsH2S affects the expression of SlCYCA2;1, SlCYCA3;1, SlCDKA1, and SlKRP2. Three-day-old tomato seedlings were treated with H2O (Con), 1 mM NaHS, 100 μΜ H2O2, 500 μΜ N,N′-dimethylthiourea (DMTU), and 0.1 μΜ diphenylene idonium (DPI), alone or their combinations for 12 h. Afterwards, SlCYCA2;1 (a), SlCYCA3;1 (b), SlCDKA1 (c), and SlKRP2 (d) transcript levels were analyzed by qPCR, and presented relative to the Con. Mean and SE values were calculated from at least three independent experiments. Bars with different letters denoted significant differences at P < 0.05 according to Duncan’s multiple range testBack to article page
