Fig. 7From: Low pH-responsive proteins revealed by a 2-DE based MS approach and related physiological responses in Citrus leavesqRT-PCR analysis of 26 low-pH responsive protein genes. Relative expression levels of genes encoding 26 low-pH responsive proteins identified in C. grandis (a-b) and C. sinensis (c-d) leaves using actin (a, c) and PRPF31 (b, d) as internal standards, and the correlation analysis of qRT-PCR results and 2-DE data (e-f). For a-d, bars represent means ± SE (n = 3). For the same genes, different letters above the bars indicate a significant difference at P < 0.05. For e and f, 2-DE data from Tables 2 and 3Back to article page
