Figure 4.

Expression analysis of all 51 LEA genes in A. thaliana. Expression was measured by quantitative RT-PCR in different organs (A), in mature leaves under different stress conditions (B), in axenic cultures under hormone induction (C) and in mature seeds (D). The color coding represents relative gene expression from 0 (yellow) to 100% (red), with 100% representing the highest expression within a given panel (compare e.g. the same leaf data as represented in A and D). See Additional file 3 for the complete data set. The numbers on the sides refer to the different LEA genes that are listed in Table 1.
