Fig. 1From: Quantitative proteomic analyses reveal that energy metabolism and protein biosynthesis reinitiation are responsible for the initiation of bolting induced by high temperature in lettuce (Lactuca sativa L.)Change in stem height in lettuce after high-temperature treatment. a Changes in stem length under suitable temperature (control) and high temperature treatment. The data (mean ± SD) are the means of three replicates with standard errors shown by vertical bars, n = 6. * and ** indicate significant differences at p < 0.05 and p < 0.01 by t-test, respectively (b) The phenotypes of lettuce under different temperature treatments. a, b, c and d represent stem growth after different temperature treatments for 0, 4, 8 and 12 d. (control at left and high temperature treatment at right); (c) The progress of flower bud differentiation. a, b, c, d and e represent the morphology of flower buds under controlled temperature for 0, 2, 4, 6 and 8 d, and f, g, h and i represent the morphology of flower buds under high temperature conditions for 2, 4, 6 and 8 dBack to article page
