Fig. 7.

Time-course expression levels of active AACA elements in Pyrus bretschneideri. The positions of the primers used for transcriptional validation are indicated in the schematic of each element in qRT-PCR region. The expression levels were detected in the fruit flesh of four developmental stages, pollen, stylet, leaf and pericarp. a–c, leaves under cold (d–f), heat (g–i), and salt (j–l) treatments for PbrAACA1_IT5 (a, d, g, j), PbrAACA4_IT11 (b, e, h, k) and PbrAACA4_IT14 (c, f, i, l). Error bars indicate the standard deviations of three biological replicates
